DEA-Based Benchmarking Models In Supply Chain Management: An Application-Orie...ertekg
Download Link > https://ertekprojects.com/gurdal-ertek-publications/blog/data-envelopment-analysis/
Data Envelopment Analysis (DEA) is a mathematical methodology for benchmarking a group of entities in a group. The inputs of a DEA model are the resources that the entity consumes, and the outputs of the outputs are the desired outcomes generated by the entity, by using the inputs. DEA returns important benchmarking metrics, including efficiency score, reference set, and projections. While DEA has been extensively applied in supply chain management (SCM) as well as a diverse range of other fields, it is not clear what has been done in the literature in the past, especially given the domain, the model details, and the country of application. Also, it is not clear what would be an acceptable number of DMUs in comparison to existing research. This paper follows a recipe-based approach, listing the main characteristics of the DEA models for supply chain management. This way, practitioners in the field can build their own models without having to perform detailed literature search. Further guidelines are also provided in the paper for practitioners, regarding the application of DEA in SCM benchmarking.
Logistics and Supply Chain Management-OverviewThomas Tanel
This presentation is designed to take an overview of global supply chain logistics, both in terms of today's supply chain and in the demand flow management process, so you can know how to make the most of this powerful tool. You've probably heard something about these topics. You may even be vaguely familiar with them. But how much do you really know about their strategic importance and the specific benefits you can gain from having a solid understanding of them?
Here's the best way to investigate global supply chain logistics and the impact it can have on your organization. You will have the opportunity to explore a variety of logistics areas , extrapolate their meanings in ways that are appropriate for strategic planning, and apply the techniques needed to make it all work for your organization.
Your business needs and technology are in a constant state of rapid-fire change, but you can count on one thing remaining constant: the need to align logistics strategically with your market needs in order to gain a competitive advantage. This alignment requires building a supply and demand system that truly helps you respond to worldwide changes in sourcing and ever-shifting customer demand. What is the potential effect that global trade management will have on your supply chain? How do you convert digital value inputs into logistics value-added outputs? How can you harness the power of global supply chain logistics as a significant force in the execution of your corporate strategy? How can you gain the information you need to translate abstractions into concrete benefits through supply chain management and continuous flow distribution?

HITS: A History-Based Intelligent Transportation System IJDKP
Transportation is the driving force of any country. Today we are facing an explosion in the number of motor vehicles that affects our daily routines. Intelligent transportation systems (ITS) aim to provide efficient tools that solve traffic problems. Predicting route congestions during different day periods can help drivers choose better routes for their trips. In this paper we propose “HITS” a traffic control system that integrates moving object database techniques [30, 28] along with data warehousing techniques [15].
Our system uses historical traffic information to answer queries about moving objects on road network, and to analyze historical traffic conditions to enhance future traffic related decisions.
With the continuous development and application of modern logistics technology, logistics cost has become one of the important factors of enterprise competition. For the special field of cold chain logistics distribution, cost control is particularly critical. By studying the control method of cold chain distribution cost, this paper introduces how to reasonably optimize the distribution cost while effectively controlling the distribution cost so as to improve the competitiveness of enterprises. This paper sorts out the relevant theoretical overview and conceptual analysis and analyses the current situation of cold chain distribution cost control in logistics companies. Then, the existing logistics cost control system is evaluated, and the hierarchical analysis method and model comprehensive evaluation method are used to analyse the current control system score and problems that require additional attention and find the cause of the problem. Finally, rectification suggestions are put forward to improve distribution costs to enhance the competitive strength of enterprises.
A transportation scheduling management system using decision tree and iterate...IJECEIAES
This paper aimed to develop a delivery truck scheduling management system using a decision tree to support decision-making in selecting a delivery truck. First-in-first-out (FIFO) and decision tree techniques were applied to prioritize loading doors for delivery trucks with the use of iterated local search (ILS) in recommending the route for the transport of goods. Besides, an arrangement of loading doors can be assigned to the door that meets the specified conditions. The experimental results showed that the system was able to assign the job to a delivery truck under the specified conditions that were close to the actual operation at a similarity of 0.80. In addition, the application of ILS suggested the route of the food delivery truck in planning the most effective transportation route with the best total distance.

New Challenges within Transportation and Logistics Management
1. Introduction
In a world that has fully embraced globalization and regional trade, transportation has become one of the most important businesses processes which enable effective carriage of raw materials to the manufacturers and manufactured goods to the end user. Currently, all the means of transportation are effectively used depending on the preference of the client. This crucial business process has led to the emergence of the transport logistics managers whose main role is to ensure that goods being transported reach their destination safely and on time. Over the years, transportation logistics has become one the most important process in the supply chain of any business as the key to satisfying customer demands and gaining a competitive advantage. However, the growth of the transportation and logistics industry has led to the development of new challenges over the years which continue to affect logistics management. The main challenge within the transportation and logistics management results from planning and risk management which has been caused by the changing environments within the industry. This paper seeks to investigate some of the planning and risk management challenges by answering the question; “what are the new challenges facing logistics managers and how can they be tackled?” It will outline three major challenges within transportation and logistics management and discuss probable solutions to each.
2. Literature Review
To research the challenges within transportation and logistics management, this paper will investigate the relationship between logistics management and supply chain management so as to specifically focus on the former throughout the research. This is because there is a strong relationship between transportation logistics management and the supply chains in that the former has become a critical element in supply chain management (Wang et al. 2016). The use of these terms in different resources has further expounded on this relationships forming the definition of these terms as follows: Logistics management is the act of organizing for the commercial transportation of goods or raw materials by ensuring that the transportation systems maintain an effective flow whereby the products being transported can reach the receiver safely and on time (Christopher, 2016). This activity incorporates different procedures such as recording data and information about the flow of goods, warehousing, and transportation.
According to Wang et al. (2016), it is the role of transportation and logistics managers to ensure quality handling of all the data and figures which account for daily operations and ensure that there is smooth coordination of tasks within a tran.
A combined fuzzy AHP with fuzzy TOPSIS to locate industrial supporting bonded...TELKOMNIKA JOURNAL
Raw material availability is critical for the sustainability of industrial activity. A bonded logistics centre is required as a multipurpose warehouse for the storage of raw commodities, particularly those imported from other countries. The operationalization of bonded logistics centers in terms of supplying raw materials effectively and efficiently is largely location dependent. Proper facility placement is critical for resolving the storage issue and boosting the efficiency of the transportation system. The purpose of this article is to suggest a technique for locating a bonded logistics centre. In an unpredictable context, decision making requires a range of criteria generated from knowledge and stakeholder experience. As a result, this work proposes the combination of the fuzzy analytic hierarchy process (FAHP) with the fuzzy technique for ordering preferences by similarity to ideal solution (FTOPSIS). By disclosing linguistic characteristics, fuzzy numbers contribute to the resolution of ambiguity and imprecision. Obtaining the weighted value of the criteria and sub-criteria using fuzzy AHP. Using fuzzy TOPSIS, determining alternate preferences based on weighting factors. Its use lies in being able to distinguish between criteria that provide advantages and those that generate expenses. The findings indicate that the selected option is the one that is most closely related to the positive ideal.

The objective of this article was to demonstrate the research and use of an operations analysis model unique to logistic activities that could integrate the use of three tools to identify and analyze problems in a process and to prove the interdependence of losses and gains between the various factors that make up an activity. In this proposal the
research of context, concepts, application and evaluations on the models chosen for the integration was made. After designing the integrated model, it was tested in a real case
of application and the results of the analysis were obtained, taking care to contextualize all the technical, social and cultural aspects involved in the process. In the end, the conclusion
exposed the positive and negative aspects of the logistic process evaluated and demonstrated the effectiveness of the integration of tools, identifying opportunities for improvement with the prioritization and indication of a tool for the solution of the deviations.

Enterprise Excellence is Inclusive Excellence.pdfKaiNexus
Enterprise excellence and inclusive excellence are closely linked, and real-world challenges have shown that both are essential to the success of any organization. To achieve enterprise excellence, organizations must focus on improving their operations and processes while creating an inclusive environment that engages everyone. In this interactive session, the facilitator will highlight commonly established business practices and how they limit our ability to engage everyone every day. More importantly, though, participants will likely gain increased awareness of what we can do differently to maximize enterprise excellence through deliberate inclusion.
What is Enterprise Excellence?
Enterprise Excellence is a holistic approach that's aimed at achieving world-class performance across all aspects of the organization.
What might I learn?
A way to engage all in creating Inclusive Excellence. Lessons from the US military and their parallels to the story of Harry Potter. How belt systems and CI teams can destroy inclusive practices. How leadership language invites people to the party. There are three things leaders can do to engage everyone every day: maximizing psychological safety to create environments where folks learn, contribute, and challenge the status quo.
Who might benefit? Anyone and everyone leading folks from the shop floor to top floor.

Abstract
This paper proposes an innovative uncertainty management using a stochastic model to formulate logistics network
starting from order processing, purchasing, inventory management, transportation, and reverse logistics activities. As
this activity chain fits well with Markov process, we exploit the very principle to represent not only the transition
among various activities, but also the inherent uncertainty that has plagued logistics activities across the board. The
logistics network model is thus designed to support logistics management by retrieving and analyzing logistics
performance in a timely and cost effective manner. The application of information technology entails this network to
become a Markovian information model that is stochastically predictable and flexibly manageable. A case study is
presented to highlight the significance of the model.
Keywords: Logistics network; Markov process; Risk management; Uncertainty management.
1. Introduction
Logistics management concerns with how to optimize the efficiency of logistics activity in a timely and cost effective
manner. This can be accomplished through a well-designed logistics network. Traditional logistics network design
transfers products from manufacturers to customers and accepts return of disposed products from customers to
manufacturers (Lee et al., 2010). Consequently, the logistic network management can be categorized into two types
with respect to the product flow, namely, outbound and inbound logistics flows. S.A (2008) claimed that capacitated
network could be used to analyze possible long-term transportation to reduce the distribution cost, having demand as
an uncertain parameter. The distributors who serve as middlemen in the network of suppliers, warehouses, and
customers must be reliable, flexible, and cost awareness. Their role is to select suppliers that will deliver products to
destination stores or warehouses and to assign warehouse to customers (Erol and Ferrell Jr, 2004). From the
distributor’s standpoint, their net profit will increase if logistics support increases the profit margins or reduces
expenses or inventory (Magrath and Hardy, 1992). Problems arise when distributors frequently have conflicting
objectives such as minimizing cost and maximizing customer’s satisfaction. They must find a proper mix of cost
effectiveness and level of customer’s satisfaction (Erol and Ferrell Jr, 2004). The key to this right mix is management
and control of distribution costs. Many firms use enterprise resource planning (ERP) and information systems (IS) as
logistics management tools to attain better perceived competitive advantages (Tilokavichai and Sophatsathit, 2011).
The increased emphasis on supply chain management, ERP, and the need to develop models with appropriate
representation of transportation considerations must be further enhanced to achieve any measurable logistics support
(Swenseth and Godfrey, 2002). Rodriguez and Vecchietti (2010) agreed that the inventory, purchasing, delivery,
demand and price uncertainties were major contributing problems of the supply chain. They solved the problem using
non-linear programming technique. Another essential issue in logistics management is inventory management which
poses an important problem in every industry as a tradeoff between customer’s satisfaction and capital investment. The
research conducted by Swenseth and Godfrey (2002) demonstrated that economic order quantity models could be

incorporated into inventory replenishment decisions. As the buyer and seller marketplace can be handled through
e-commerce or third-party logistics providers in order to maximize customer’s satisfaction (Nevins and Money, 2008),
many models and methods have been developed to accommodate such an optimization problem. However, few studies
have addressed the comprehensive design of logistics networks under uncertainty.
Although some research endeavors attempt to describe uncertainty that involves in logistics activities, the analyses are
conducted on pair-wise or adjacent activities. This fails to capture cross-relationships among various activities in the
logistics network. We envision such intertwined relationships that are inherent to the logistics chain. We propose a
working stochastic model to represent the overall logistics perspective and pertinent indicators for firms to improve
logistics performance toward better business decisions. The model makes use of Markov process to link order
processing, purchasing, inventory management, transportation, and reverse logistics activities under uncertainty.
Analysis detail will be described in subsequent sections.
The organization of this paper is as follows. Section 2 recounts some related literature and important issues in the area.
Section 3 presents the Markov model, including notation used, the meaning of parameters, variables, constraints, and
others. Section 4 describes a case study to demonstrate the viability of the proposed model. Section 5 discusses some
essential findings and potential future course of action.
2. Literature Review
2.1 Logistics Network Model
Traditional business model is articulated in three stages: production, distribution, and sales. Each one of these stages is
usually managed by a different company, or by a different branch of the same company (S.A, 2008). Logistics activities
for distribution products start from order processing, inventory management, purchasing and procurement,
transportation, and reverse logistics (Lai et al., 2010; Wu and Huang, 2007; Aptel and Pourjalali, 2001; Ngai et al.,
2008). A logistics network model thus becomes very important in logistics management (Listes, 2007). Lee, et al.
(2010) developed a sustainable logistics network under uncertainty using stochastic programming to attain cost savings
and pollution reduction as a result of sharing material handling equipment and infrastructure. El-Sayed, et al. (2010)
developed forward-reverse logistics network design under risk model to maximize the total expected profit. The
problem was formulated in a stochastic mixed integer programming and decision making process. Pishvaee, et al.
(2009) applied a stochastic programming model with an integrated forward/reverse logistics network design under
uncertainty to minimize the total costs including fixed opening cost, transportation cost, and processing costs. S.A.
(2008) applied stochastic programming to design capacitated network analyzing possible long-term transportation of
oil derivatives by pipeline, truck, railway, and ship so as to reduce the distribution cost. Moreover, Wilcox, et al. (2011)
applied Markov model to handle reverse logistics operations and related financial management of the reverse
logistics/return processes. Lee, et al. (2010) applied stochastic programming in reverse logistics to minimize cost and
time. Listes (2007) developed a supply and return network using stochastic programming in demand and forecasting,
transportation, and reverse logistics. One of the reasons why the transportation issue has become the mainstay of
logistics management is because the annual transportation costs are the largest expense in logistic system where the
majority of costs incurred depend on volume of products (S.A, 2008). The aforementioned models have wide range of
applications in logistics reliability, liquidity, cost efficiency, time reduction, etc. However, previous researches
assumed that the logistics network was a continuous process, and hence the design parameters for the logistics network
mostly focused on forward logistics or reverse logistics. Table 1 summarizes some of the techniques and logistics
activities for logistics models from previous studies.
2.2 Risk Management
Logistics have become a major component of competitive strategy to enhance organizational productivity and
profitability. Unfortunately, the constituent activities in the logistics chain do not operate without chances of failure to
meet the desired objective. This window of missing the pre-established target is known as risk. Hence, risk
management in logistics activities is a very important factor of competitive advantage formula. El-Sayed, et al. (2010)
proposed a multi-period multi-echelon forward and reverse logistics network model under risk to maximize the total
expected profit. Ramanathan (2010) explored the relationships between logistics performance and customer loyalty
that affected by risk characteristics of products and efficiencies of the websites in terms of price and ambiguity of

products. Cope, et al. (2010) delivered actionable policy recommendations based on consumer preferences for different
approaches to food management by risk communication such as sharing knowledge of consumer risk perceptions and
information needs. Tsao (2011) developed an inventory model with non-instantaneous delivery under trade credit and
logistics risk. The model determined the optimal replenishment policy for a retailer, given uncertainties in a supply
chain which were due to unforeseeable disruption or various types of defect such as shipping damage, missing parts,
misplaced products and disasters, etc.
2.3 Stochastic process and Markov model
Stochastic programming is an optimizing technique using probabilistic information to solve large scale probabilistic
optimization problems (Yu and Li, 2000). Markov decision process is a sequential decision-making stochastic process
characterized by five elements: decision epochs, states, actions, transition probabilities, and rewards (Puterman, 1994).
Many areas of science and technology use Markov chain to resolve complex problems of the underlying factors
attributing to different types of transitions, reverse transitions, and repeated transitions (Ataharul Islam and Chowdhury,
2006; S.A, 2008). Markovian formulations are useful in solving a number of real-world problems under uncertainties,
such as determining inventory levels for retailers and scheduling maintenance for manufacturers (Zhao et al., 2010). It
provides more flexibility in statistically examining multiple transitions simultaneously and predicts the future state of a
system from its present state ignoring its past history. Therefore, Markov chain is more effective at providing
predictive information for managers and offers likelihood estimations for future outcomes (Wilcox et al., 2011). Its
probabilistic nature renders the technique ideal for solving logistics problems under uncertainties, such as determining
inventory level for retailers, scheduling maintenance for manufacturers, scheduling/planning in production
management, and resource planning for time, cost, and human (Gayon et al., 2009). In addition, as the Just-in-Time
(JIT) mode is introduced, the branches need not stock large inventories. The inventory cost can also be reduced (Zhao
et al., 2010). A transient state can be formally defined as state from which the unit can change before leaving the system.
Examples of transient states that could be considered might include purchasing, replenishment, distribution, etc. The
goals are minimum cost, minimum time, and maximum profit.
Logistics models were developed by many techniques such as stochastic programming, Markov decision process, EOQ,
etc., as summarized in Table 1. These techniques in turn were further applied to outbound, inbound, or reverse logistics
in a pair-wise fashion. The lack of holistically integrated study of these activities left logistics problems hard to reckon
with. The advent and application of information technology merely speeds up routine activities but leaves the inherent
complexity untouched. The introduction of Markov model to analyze transition probabilities in logistics activities
entails a promising means to tackle such obstacles. As transitional capability of the Markov process can represent
multi-stage flow of logistics activities under uncertainty, the resulting representative model can be used for further
study on minimizing costs, time, opportunity loss, and maximizing flexibility, where different activities can be
transited within the logistics distribution network.
2.4 Logistics activity based costing
Supply chain management requires accurate cost data regarding all activities and process within the organizations.
Activity-Based Costing (ABC) can significantly contribute accurate cost data regarding all activities in supply chain
management (Askarany et al., 2010; Gunasekaran et al., 2004). Gupta and Galloway (2003) demonstrated the
managerial implications of an Activity-Based Costing/Management (ABC/M) system for various operation
management decisions relating to product planning and design, quality management and control, inventory
management, capacity management, and work force management that support decision-making of operation managers.
Schulze, et al. (2012) applied ABC model in supply chain environment for inter-firms cost saving opportunities.
Baykasoglu and Kaplanoglu (2008) applied ABC with business process modeling and analytical hierarchy approach
for effective costing services of land transportation companies. Hung (2011) integrated approaches of ABC and
management such as five forces analysis, risk analysis, decision making, analytic network process, and fuzzy goal
programming for precise costing, managerial constraints, competitive advantage analysis, and risk management.
3. Proposed Markov model
The model is a formulation of the logistics network design that consists of outbound, inbound, and reverse logistics.
This model serves as a basis for numerous studies on logistics activity relationship to accomplish a set of designated

objectives. Qin, et al. (2009) designed the logistics network between stochastic demand and inventory control to
minimize cost under a predefined service level. The granularity of description detail depends on the context and focus
of logistics problems under study. The proposed model is applied to a case study of the logistics network design for a
distribution business. Preliminary analysis has established the working scenarios given in the previous section. During
the course of the research, it was discovered that though many distributors claimed to place high priority on regular
logistics activities, a few distributors had monitored related data with the same degree of intensity and depth of analysis
on sales effort. The actual site was conducted at XYZ Company which is a large ceramic tile and sanitary ware
manufacturer in Thailand. The true identity was withheld for confidentiality. XYZ has total annual income over 7.5
billion Baht, part of which about 150 million Baht was spent on transportation in 2011. Meanwhile, XYZ presently
handles approximately 80,000 items that make up 75 product types from 392 vendors. The average vendors’ lead time
is 8 days which account for the total inventory values of 890 million Baht. There are 1,200 staffs serving logistics
activities, or 75 percent of all employees. Over 150,000 customers visit the branches annually. There are 164 vehicles
or 90 percent of all of vehicles being deployed in customer delivery, which usually takes 2 days. The main obstacle that
hinders profitability is logistics management. Therefore, the ultimate goals of this case study do not limit to only
demonstrate how the proposed Markovian information model copes with the risk involved in the company’s logistics
network, but also exploitation of the model to optimize the costs incurred. We calculated logistics costs from financial
statement of XYZ such as wages, transportation, fuel, repair, communication, depreciation of vehicles and others,
insurance, utilities, interests, and administrative costs expended in percentage of sales. However, we could not reveal
all real data. As such, an overall logistics cost structure is categorized in four groups as follows: 1) interests from
logistics activities, 2) transportation, packaging, fuel, depreciation of vehicles, and other relating maintenance costs, 3)
wages, allowances, and welfares for logistics activities, and 4) other costs such as communication, miscellany,
depreciation, utilities, taxes, and other administrative costs.
The model was applied to internal logistics process, where financial data were provided by XYZ. The data reflected a
twelve-state Markov chain, with almost all transitions between states was tracked by ERP system. The model is not
intended to yield an exhaustive list of possible states or transitions, but rather an example demonstrates the utility of the
model. Its flexibility could be customized to suit individual distributor setting based on their logistics policy. The
analysis breakdown of XYZ logistics network by Markov process is shown in Figure 1. We measured the number of
transactions, cost per transaction, and time spent in each activity from ERP. Cost per transaction is calculated from
logistics cost structure. This is a unit performance measure of any logistics activity at a given stage. For example, order
processing (O1) and inventory management at branch (I1 and I2) both have cost per transaction of 144 Baht. This is
because all three activities are executed at the same ERP node (this is architectural dependent on ERP configuration).
The total logistics activity costs divided by all transactions executed at this node is therefore
24,500,000/(1,119+155,094+14,448) = 144 Baht. Similarly, a reflexive link at O1 designates a pending status of 1,119
transactions at 144 Baht that affected the annual income by 16,543,457 Baht or about 3 percent.
Figure 1 displays the probability that associates with each transition in the logistics activity network. The latter
represents a complete logistics chain based on Markov process at time t (in month), t = 1, 2, …, n. A sale transaction
starting at a branch can be filled with probability 0.91 and delivery to customer by the branch with probability 0.43. If
the branch is out of stocks with probability 0.08, a purchase order is initiated with probability 0.99 in accordance with
normal branch replenishment by the distribution center (DC). In order to minimize the expected transportation cost,
XYZ needs to establish a viable delivery decision based on available information. The result will furnish several
alternate routes, each of which is associated with uncertainty that is translated into time, cost, flexible course of action
for customer, and adaptability to JIT principle that altogether meeting the demands in the given period (t, t+j), where j
is the number of transition steps in the Markov chain.
Figure 2 shows the transition matrix Q of the logistics network depicted in Figure 1. A state describes the option of the
logistics activity at time t. The entry Sij represents the transition probability from state i to state j. A transaction
(row-wise) beginning at O1 will remain in O1 with 0.01; transit to I1 with 0.91; and to I2, with 0.08.
Consider when a customer places an order at the branch office. The order is filled and eventually delivered to the
customer by the same branch office. According to the analysis breakdown, there are seven possible routes to get from
order processing (O1) to transportation to customer (T2) as shown in Table 2. The state of a delivery to customer is
determined only by previous state. In the first route, we begin at O1 and proceed to I1 then T2 with probabilities 0.91 and
0.43, respectively. In the second route, the items are out of stock (I2) which calls for additional issuance of a purchase
22
5. Information and Knowledge Management www.iiste.org
ISSN 2224-5758 (Paper) ISSN 2224-896X (Online)
Vol 2, No.5, 2012
order at purchasing and procurement (P1). Upon replenishing stock (I1), the items are sent to transportation to customer
(T2) with probabilities 0.08, 0.99, 0.26, and 0.43, respectively. In the third route, similar scenarios to the second route
are resulted. Fortunately, DC carries sufficient desired items to fill the stock at the branch office and the case is closed.
The fourth route is similar to the second, except replenishments go to DC first before being discharged to the branch
office, while the fifth route relays replenishments to cross dock and follows the same track. The only undesirable
situation occurs in the sixth route where orders are returned due to wrong shipment, quantity, or quality that must be
reprocessed to fulfill the order. Nevertheless, the risk is low (0.0050) but the penalty is extremely costly. Finally, the
seventh route exhibits a typical order request to DC, filled, and return with the desired product to the branch before
shipping it to the customer by the same branch.
To determine the probability of going from A to B in one transition, denoted by P(AB), follow the established Markov
process. Hence, the probability P that an order will be delivered to customer by branch based on all of the above
scenarios is
P = P(O1I1)P(I1T2) + P(O1I2)P(I2P1)P(P1I1)P(I1T2) + P(O1I2)P(I2Id1)P(Id1I1)P(I1T2) + P(O1I2)P(I2P1)P(P1Id1)P(Id1I1)
P(I1T2) + P(O1I2)P(I2P1)P(P1Id2)P(Id2I1)P(I1T2) + P(O1I1)P(I1T2)P(T2R1)P(R1I1)P(I1T2) + P(O1I1)P(I1Id1)P(Id1I1)P(I1T2)
Thus, P = (0.91)(0.43) + (0.08)(0.99)(0.26)(0.43) + (0.08)(0.01)(0.62)(0.43) + (0.08)(0.99)(0.41)(0.62)(0.43) +
(0.08)(0.99)(0.26)(1.0)(0.43) + (0.91)(0.43)(1.0)(0.03)(0.43) + (0.91)(0.01)(0.62)(0.43) = 0.43
This tells us that an order has a 43% chance to reach the branch for on-time delivery. If we consider all possible
two-step transitions based on the same scenarios, we obtain Q2= Q x Q as shown in Figure 3.
As the values of the Q matrix are derived from company’s internal item tracking of logistics activities over several
periods, it is possible to predict the expected number of sale order transactions, or the number of transactions in each
delivery type, by customer, by branch, by vendor, etc., for enterprise resource planning and increase customer’s
satisfaction.
4. Case studies and managerial implications
Firms in various industries are implementing logistics systems to reduce costs and increase profits. Due to the
unpredictable nature of logistics, firms must strive to achieve high service level agreement to attain customer’s
satisfaction. The proposed model will offer top executives to set the target of logistics performance indicators based on
information from Markov model such as lead time to customer, opportunity cost, transportation, and inventory costs.
Logistics manager can exercise the above policy to meet the target by predicting possible routes to preventing
subsequent problems and risks. They can monitor and identify implementable solutions bearing potential risks and
problems to arrive at viable course of action. The food and beverage sector, for instance, must have intensive control
over both incoming and outgoing logistics of raw materials and finished goods owing to their perishable nature.
Moreover, stricter regulations and consumer awareness impose higher requirements for food quality and safety (Losito
et al., 2011). As uncertainty and unpredictability of food demands are a normal problem of this sector, they must pay
close attention to distribution level problems such as lead time, abrupt and abnormal demands (Kumar and Nigmatullin,
2011). Bozkir and Sezer (2011) examined food demand prediction by applying chi-squared automatic interaction
detection, classification, and regression trees, while others resort to tools such as Just-in-Time (JIT) for cost reduction
(Zarei et al., 2011). We studied FF Company who produces fruits and fresh vegetables ready to cook and eat for export
to European countries. The company is certified with EURAPGAP, BRC, and BRC/IOP. They encountered a big
opportunity loss problem as sales plummeted from 7% down to 3 %. The main causes are the high price and shortage of
unseasonal agricultural raw materials which in turn affect freight quality and disposal cost.
The logistics activity relationship matrix of FF Company consists of order processing and inventory management
which are mutually dependent on average duration (days) of supply to customers, inventory management, purchasing/
procurement, and measured by economic order quantity and reorder point (Kumar and Nigmatullin, 2011). Typically,
perishable food transportation involves multiple variables such as distribution centers, product varieties, carriers,
vehicles, and customers. These variables attribute to another utmost important controlled variable, i.e., temperature
which often fluctuates by many factors. Besides, the delivery vehicles usually have multiple customer deliveries per
cycle (White III and Cheong, 2012; Ahumada and Villalobos, 2011).
In Table 3, there are six possible routes from order processing (O) to transportation to wholesaler (T). The state of a
23

Vol 2, No.5, 2012
delivery to the wholesaler is determined only by previous state. In the first route, we begin at O and proceed to
purchasing and procurement issuance of a purchase order (P). After that fruits and vegetables are cut and pack for
ready to cook and eat (M). Finally, the items are sent to transportation to wholesaler in Europe by air (T) with
probabilities P(O-P-M-T). In this route, raw material and finished goods are not buffered anywhere. As such, the
hand-off between states can be treated as a JIT delivery. In the fifth route, the concern is on raw material (I1) that must
have enough quantity and in good quality. Thus, the Markov model can support managers in making decision and
predict on customer’s demand, opportunity loss, EOQ, reorder point, disposal cost, etc.
For service industry such as hospitals, logistics activities consist of purchasing, physical supply, receiving, inventory
management, internal distribution to medical units, and management information systems. Distribution operations
usually focus on inventory scheduling decisions. The variables involved are: when to place order and deliver to each
care unit. Therefore the activities balance through the purchasing cycle (Lapierre and Ruiz, 2007). Moreover,
distribution of suppliers such as central warehouse or direct vender distribution and volume of medicine being
distributed affect logistics performance of the hospital (Aptel and Pourjalali, 2001). In this case, the speed of service is
an important variable in servicing the patients. The Markov model can be deployed to improve such a work flow to
reduce cost, increase customer’s satisfaction, and safe health care of patients.
It is apparent that Markov model can be applied in several industries such as food, electronics, fashion, and services. It
helps solve problems such as over stock, severe delays, inaccurate product forecasts, inefficient service flow, lost sales
and liquidity. The information from Markov model can be used to set target, predict opportunity cost, time, service
level, reduce inventory, eliminate bullwhip effect, and improve communication. One direct IT application is direct
manufacturer to customer sales (in the case of Compaq) which in the context of the proposed logistics network model
is just a jump from regular sale order distribution channel in the supply chain, bypassing wholesalers and retailers to
customers. The risk paid off beautifully.
5. Conclusion and future research
This paper has explored the logistics network activity management under uncertainty. In order to account for the
uncertain characteristics of the logistics network, the Markov model has been developed where the demands of
outbound logistics, inbound logistics, and returned product from customers are assumed to be stochastic parameters
with known distribution. The model addresses some recalcitrant logistics activity problems that have high holding
costs and uncertain demands. The application of Markov chain provides relevant predictions for managers and
likelihood estimations for future outcome. Since logistics management is a part of the strategic map that attributes to
the firm’s competitive advantage (Quezada, 2009), we selected a case study of a large-scale logistics network firm to
demonstrate the viability of the proposed model. The results have not only shown product distribution alternatives, but
also demonstrated an integrated systematic method that yielded cost effective logistics network performing at high
customer’s satisfaction level.
The case study shown in Figure 1 also encompasses a number of valuable information to be extracted. The opportunity
loss in order processing with probability 0.01 or 16,543,457 Baht is caused by inadequate stock to fill the order. This in
turn will affect liquidity situation because the branch does not generate sales and remains to reckon with creditors.
Although XYZ has its own DC that is equipped with automatic inventory replenishment system, but the risk of being
out of stock exists. Analysis on activity flow can determine the time spent, associated costs, and risk involved of a sale
order (O1), encountering out of stocks situation (I2), issuing a corresponding PO (P1), before proceeding to either DC
stocks (Id1) or cross dock (Id2). Therefore, top executive, middle managers, operation managers, and other parties
involved could communicate, discuss, or lay out strategic planning to be in-line with organization objectives. Moreover,
the company can cooperate with vendors and customers using the result information obtained from Markov analysis to
meet the target logistics mission, while minimizing cost, time, improving customer’s satisfaction and competitive
advantage over its competitors. It is thus apparent that the information is attributive to decision making in planning and
controlling resources, transportation, and risk management.
The enormity of cumulative uncertainties that are inherent to all stages of the logistics chain has prompted us to delve
into the overall cost structure. From the externally imposing service level and demands from customers and
competitors, various holding costs, transportation cost, JIT lot size, etc., have affected the entire downstream
operations in branches and vendors alike. We also found that the unraveled uncertainties could in fact be directly
translated into anticipatory risks that the company could mitigate or avoid. Thus, we can predict lead time reduction by

JIT, as well as the associated costs derived from suppliers and customers’ data. Future research will explore
organization cost analysis by applying ABC that incorporates additional variables such as number of staffs in each
logistics activity, vehicles, transportation zones, sales representatives, vendors, order distribution, and working time in
each logistics activity. A precautionary warning is that adoption of ABC in smaller firms needs more attention than
larger firms in light of risk and uncertainty involved.
The proposed model can very well suit different industries such as food, electronics, machinery, fashion, and service
sectors, as long as there are logistics activities involved. In particular, we are gathering in-depth information on food
industry as the perishable nature mandates a highly efficient logistics network to reduce time-to-market which is the
life line of their business survival. We also plan to apply the proposed technique on returned goods from stocks at
branch to DC (R2), customer to branch stocks (R1), and DC stocks to vendors (R3), thereby minimizing costs of
exchange, staging, scrap (due to damage), and out dated stock clearance. Owing to the volume of such returned goods,
efforts to reduce the probability of loss sales ignited an innovative in-house product development to churn out
artistically design of blending piece scrap to a new product line. The outlook is promising as demand steadily grows.
Our future work will incorporate dynamic prediction by a weighted coefficient of variables. Consequently, the
introduction of Markovian information model will be conducive toward effective minimizing cost and predicting
future outcome that further enhances the competitive advantage of the firm.
