This paper is built on a study in relation to transportation problem as it affects most organisational decision in a decomposed setting. The case study used in this work is Dangote cement factory (in Ibese, Nigeria) with three sources and four destinationscentres. The factory is supported by increasing number of cement delivery trucks. Some models for solving balanced transportation problems (TPs) are considered in order to determine the optimal and initial basic feasible solutions (IBFS). From the analysis, it is observed that Modified Vogel Approximation Method (MVAM) is a better method. This is partly because MVAM considers each unit cost in its solution algorithm and minimises total cost comparatively with Vogel Approximation Method (VAM). The results arefurther justified and validated using windows version 2.00 Tora package.
Aerodynamic Drag Reduction for A Generic Sport Utility Vehicle Using Rear Suc...IJERA Editor
The high demand for new and improved aerodynamic drag reduction devices has led to the invention of flow control mechanisms and continuous suction is a promising strategy that does not have major impact on vehicle geometry. The implementation of this technique on sport utility vehicles (SUV) requires adequate choice of the size and location of the opening as well as the magnitude of the boundary suction velocity. In this paper we introduce a new methodology to identifying these parameters for maximum reduction in aerodynamic drag. The technique combines automatic modeling of the suction slit, computational fluid dynamics (CFD) and a global search method using orthogonal arrays. It is shown that a properly designed suction mechanism can reduce drag by up to 9%.
Operation Research involves determining an optimum solution to a distribution problem. In order to suitably plan and assign vehicles to different routes, organizations can use the listing method described in the North-West corner rule. Research methods such as PERT and CPM are useful for timely completion of a project.
The above slides brought to you by Welingkar’s Distance Learning Division are on Operation Research Techniques in Transportation. Suitable operation research techniques are used to derive optimum solution to a distribution problem. North-West rule is explained in the presentation and PERT and CPM is used for timely completion of a project.

ASEM 2012 How to define the problem Hedgepetholiverinva
This document discusses a case study of using RFID tracking technology to track dump trucks during an Alaskan road construction project. The initial problem statement was to compare manually tracking trucks to using RFID technology. However, over the course of the project, the problem statement, assumptions, and metrics changed significantly. By the end of the project, the metrics had expanded to include 19 variables but were ultimately reduced back to just two variables - time and distance traveled by trucks. The shifting problem definition and metrics made analyzing the results difficult and inconsistent. The document emphasizes the importance of clearly defining the problem statement and metrics upfront to avoid an unstable or changing problem definition over the course of a research project.
09 Parking Studies (Traffic Engineering هندسة المرور & Prof. Saad AlGadhi)Hossam Shafiq I
This document discusses parking studies and characteristics. It covers four key topics: parking supply needs, parking generation rates, parking studies including accumulation and duration, and parking facility design. Parking supply needs depend on land use type and density as well as public transportation access. Parking generation rates relate occupied parking spaces to development size based on ITE data. Parking studies use methods like license plate surveys to collect data on accumulation, duration, and turnover. Parking facility design aims to provide convenient, efficient, and secure parking while minimizing costs and impacts.

A New Method for Solving Transportation Problems Considering Average PenaltyIOSRJM
Vogel’s Approximation Method (VAM) is one of the conventional methods that gives better Initial Basic Feasible Solution (IBFS) of a Transportation Problem (TP). This method considers the row penalty and column penalty of a Transportation Table (TT) which are the differences between the lowest and next lowest cost of each row and each column of the TT respectively. In a little bit different way, the current method consider the Average Row Penalty (ARP) and Average Column Penalty (ACP) which are the averages of the differences of cell values of each row and each column respectively from the lowest cell value of the corresponding row and column of the TT. Allocations of costs are started in the cell along the row or column which has the highest ARP or ACP. These cells are called basic cells. The details of the developed algorithm with some numerical illustrations are discussed in this article to show that it gives better solution than VAM and some other familiar methods in some cases.

Realistic road path reconstruction from GIS datahanguyenhoang
We introduce a new approach to construct smooth piecewise curves representing realistic road paths. Given a GIS database of road networks in which sampled points are organized in 3D polylines, our method creates horizontal, then vertical curves, and finally combines them to produce 3D road paths. We first estimate the possibility of each point of being a junction between two separate primitive curve segments. Next, we design a tree-traversal
algorithm to expand sequences of local best fit primitives which are then merged together with respect to the G1 continuity constraint and civil engineering rules. We apply the Levenberg-Marquardt method to minimize the error
between the resulting curve and the sampled points while preserving the G1continuity

This document summarizes a research study that proposes a hybrid algorithm using Dijkstra and Floyd-Warshall algorithms to find conflict-free routes for multiple autonomous guided vehicles (AGVs) in a warehouse distribution system. The goal is to optimize the shortest distances and schedules for AGVs performing pickup and delivery tasks within specified time windows. A grid topology route model is used to represent the warehouse environment. The hybrid algorithm combines dynamic programming approaches to determine optimized, conflict-free routes for multiple AGVs operating simultaneously while meeting time constraints for tasks at workstations. The algorithm aims to improve efficiency of autonomous vehicle systems for goods distribution in manufacturing warehouse applications.
This document summarizes a case study on developing an economic replacement decision model to identify the optimal economic lifetime of drilling machines used in the Swedish mining industry. The proposed model considers operating and maintenance costs, purchase price, resale value, and time value of money using discount rates to calculate the equivalent present value of costs. The model finds that the absolute optimal replacement time for a drilling machine used in one underground mine in Sweden is 115 months. Sensitivity and regression analysis show that maintenance cost has the largest impact on the optimal replacement time.
The document describes modeling and forecasting of tur production in India using the ARIMA model. Time series data of tur production from 1950-1951 to 2014-2015 was analyzed using time series methods. The autocorrelation and partial autocorrelation functions were calculated and the Box-Jenkins ARIMA methodology was used. The ARIMA(1,1,1) model was found to be appropriate based on diagnostic checking. Forecasts of tur production from 2015-2016 to 2024-2025 were then calculated using the selected ARIMA(1,1,1) model. The forecasts could help policymakers plan for future requirements of tur seed, imports, and exports.
Development of Transport Scenarios for Denmark: An Iterative and Participator...IEA-ETSAP
This document describes a framework for developing transport scenarios for Denmark through an iterative process involving qualitative scenario workshops and quantitative modeling using the TIMES-DK energy system model. The goal is to bridge qualitative and quantitative tools to create robust and sustainable pathways for Denmark's future energy and transport system. Scenario workshops were held with citizens, stakeholders, and researchers to discuss drivers and design scenarios, which were then modeled in TIMES-DK and results assessed. Challenges addressed include simplifying the scenario interface and reducing run-time to allow for greater interaction and testing of different policy pathways. The process provides opportunities for discussion, validation of assumptions, and understanding of system dynamics and interdependencies.
Transportation modeling and planning ( The Four-Step Model )Ahmad Ali Miftah
This document describes transportation modeling and planning using the four-step model. It discusses data collection and characterization for the study area of North Cyprus.

TE004, A Study On Feasible Traffic Operation Alternatives At Signalized Inter...Saurav Barua
This study analyzed traffic operations at a busy signalized intersection in Dhaka, Bangladesh using traffic simulation software VISSIM. Four alternatives were considered: 1) banning right turns, 2) optimizing signal timing, 3) constructing a one-way overpass, and 4) constructing two overpasses. Traffic data was collected and used to calibrate the VISSIM model. The alternatives were then simulated and evaluated based on average speed, delay, and queue length. Constructing a single overpass was found to provide the greatest benefits, increasing average speed by 250% and reducing delays and queues by over 90%, making it the recommended alternative to improve traffic flow at the intersection.

Integrating Tabu Search and MPOSH Heuristic for Solving a Multiple-Period Oil...drboon
Multi-period oil station replenishment problem is one type of vehicle routing problem that has constraints such as number of truck, capacity of truck’s compartments and capacity of tank space in each station. Generally, the objective of vehicle routing problem is to minimize the transportation cost. Solving the large problem to find the best solution is complex and difficult. Because, in the large problem, many conditions and parameters are calculated, then the computer calculation is time consuming. In this study, the Multi-Period Oil Station Replenishment Heuristic (MPOSH), and integration between MPOSH and Tabu Search called Tabu MPOSH are constructed for performance tests. The problems are investigated with varied sizes, such as: number of stations are 5, 10, 20, 50, and 75 stations, and the demand frequencies in each station are 5, 10, and 20 days, the trucks used in transportation are 2 to 38 trucks, and the demands are two values (maximum and minimum). The results show the hybrid between MPOSH and Tabu Search or Tabu MPOSH with number of run 350 cycles (iterations) yields the better solution than others. Observantly, setting the higher iterations will improve the solution results. The solved information shows number of days for delivery, number of trucks, and stations of trips in each day.
A Minimum Spanning Tree Approach of Solving a Transportation Probleminventionjournals
: This work centered on the transportation problem in the shipment of cable troughs for an underground cable installation from three supply ends to four locations at a construction site where they are needed; in which case, we sought to minimize the cost of shipment. The problem was modeled into a bipartite network representation and solved using the Kruskal method of minimum spanning tree; after which the solution was confirmed with TORA Optimization software version 2.00. The result showed that the cost obtained in shipping the cable troughs under the application of the method, which was AED 2,022,000 (in the United Arab Emirate Dollar), was more effective than that obtained from mere heuristics when compared
Optimizing waste collection in an organized industrial region: A case studyGurdal Ertek
In this paper we present a case study which involves the design of a supply chain network for industrial waste collection. The problem is to transport metal waste from 17 factories to containers and from containers to a disposal center (DC) at an
organized region of automobile parts suppliers. We applied the classic mixedinteger programming (MIP) model for the two-stage supply chain to the solution of this problem. The visualization of the optimal solution provided us with several
interesting insights that would not be easily discovered otherwise.

Economic Load Dispatch Problem with Valve – Point Effect Using a Binary Bat A...IDES Editor
This paper proposes application of BAT algorithm
for solving economic load dispatch problem. BAT
algorithmic rule is predicated on the localization
characteristics of micro bats. The proposed approach has
been examined and tested with the numerical results of
economic load dispatch problems with three and five
generating units with valve - point loading without
considering prohibited operating zones and ramp rate limits.
The results of the projected BAT formula are compared with
that of other techniques such as lambda iteration, GA, PSO,
APSO, EP, ABC and basic principle. For each case, the
projected algorithmic program outperforms the answer
reported for the existing algorithms. Additionally, the
promising results show the hardness, quick convergence
and potency of the projected technique.
HOPX Crossover Operator for the Fixed Charge Logistic Model with Priority Bas...IJECEIAES
In this paper, we are interested to an important Logistic problem modelised us optimization problem. It is the fixed charge transportation problem (FCTP) where the aim is to find the optimal solution which minimizes the objective function containig two costs, variable costs proportional to the amount shipped and fixed cost regardless of the quantity transported. To solve this kind of problem, metaheuristics and evolutionary methods should be applied. Genetic algorithms (GAs) seem to be one of such hopeful approaches which is based both on probability operators (Crossover and mutation) responsible for widen the solution space. The different characteristics of those operators influence on the performance and the quality of the genetic algorithm. In order to improve the performance of the GA to solve the FCTP, we propose a new adapted crossover operator called HOPX with the priority-based encoding by hybridizing the characteristics of the two most performent operators, the Order Crossover (OX) and Positionbased crossover (PX). Numerical results are presented and discussed for several instances showing the performance of the developed approach to obtain optimal solution in reduced time in comparison to GAs with other crossover operators.

Dynamic Economic Dispatch Assessment Using Particle Swarm Optimization TechniquejournalBEEI
This document presents a study that uses Particle Swarm Optimization (PSO) technique to solve the Dynamic Economic Dispatch (DED) problem for a 9-bus power system with 3 generators over a 24-hour period. The objective is to determine the optimal generator outputs at each hour to minimize total generation costs while satisfying system constraints. PSO is applied to find the optimal solution by updating generator output positions based on personal and global best cost values.

Multi objective economic load dispatch using hybrid fuzzy, bacterialIAEME Publication
The document summarizes a research paper that proposes a new approach for solving the economic load dispatch problem using a hybrid fuzzy, bacterial foraging-Nelder–Mead algorithm. The economic load dispatch problem minimizes generation costs while satisfying load demand under system constraints. The proposed approach considers generation costs, spinning reserve costs, and emission costs simultaneously. It also accounts for valve-point effects, prohibited operating zones, and other practical constraints. A hybrid bacterial foraging and Nelder–Mead algorithm combined with fuzzy logic is used to solve the optimization problem. Simulation results show the advantages of the proposed method in reducing total system costs.

This paper presents an optimization of corridor observation method (COM) which is an applicable optimization algorithm based on the evolutionary algorithm to solve an environmental and economic Dispatch (EED) problem. This problem is seen like a bi-objective optimization problem where fuel cost and gas emission are objectives. In this method, the optimal Pareto front is found using the concept of corridor observation and the best compromised solution is obtained by fuzzy logic. The optimization of this method consists to find best parameters (number of corridor, number of initial population and number of generation) which improve solution and reduce a computational time. The simulated results using power system with different numbers of generation units showed that the new parameters ameliorate the solution keep her stability and reduce considerably the CPU time (time is minimum divide by 4) comparatively at parameterization with originals parameters.
The transportation model is a linear programming model used to determine the least-cost solution to shipping goods from multiple origins to multiple destinations. The modeling process involves setting up a transportation matrix with supply, demand, and cost data. An initial feasible solution is found using methods like the northwest-corner rule or lowest-cost method. The stepping-stone algorithm is then used to find the optimal solution. Issues like unbalanced supply and demand are handled with dummy entries. The model aims to minimize total transportation costs while meeting all supply and demand constraints.

Living in 21st century in itself reminds all of us the necessity of police and its administration. As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%.

ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.

The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Ogun state and other South west states in Nigerian markets with production capacity of 6.0
MT cement produced from lines 1, 2 and 3 respectively. The factory is supported by
increasing number of cement delivery trucks. Hence, the need for enhanced means to resolve
transportation problem (TP). This data article therefore aims at making informed decision on
effective techniques for finding initial basic feasible solution and applying Modified Vogel
Approximation Method (MVAM) to determine the optimal solution to the corresponding
balanced TP. Table 1 contains the sources alongside the destinations of the trunk lines, Table
2 contains the General Transportation Problem Tableau (GTPT), while the analysed data are
presented in Tables 3-5 and Figures 1-4. Related work on Transportation, economic, and
financial problems of relevance to this study can be found in [1-15].
The simplest transportation problem was first presented in 1941 and developed in 1949
and 1951. Since then several extensions of transportation models and methods have emerged.
Among early pioneers of transportation problems (TPs) are Hitchcock [16] through his
paper “the Distribution of a Product from Several sources to numerous Localities”. Closely
related to Hitchcock is Koopman [17] who with his paper “Optimum Utilization of
Transportation System” simplified better understanding of transportation methods involving
a number of shipping sources and destinations. Gass [5] in his own contribution explains
practical issues for solving transportation problems and offered comments on various aspects
of transportation problem (TP) methodologies along with discussions on the computational
results by various researchers. Tzeng, Teodorovic, and Hwang, [18] applied time TP to
formulate a LP that minimizes cost of transportation to distribute and transport imported Coal
to power plants by determining the quantity and quality required amounts under stable supply
with least delay. Their model yield optimum results and serves as decision support system to
manage coal allocation, voyage scheduling and dynamic fleet assignment problems. Since
then, a number of researchers such as Sonia [13] contributed to Transportation Problem in
area of decision support. However, their work was restricted on time transportation problem.
A number of researchers including Wahead and Lee [19], and Joshi [20], in “Optimization
Techniques for Transportation Problems of Three Variables” proposed for the procedure for
full allocation of available total quantity required in each cell.
The existing techniques or methods are the minimum cost rule method, Northwest corner
rule method, Vogel approximation method, Russell approximation method and Roland
Larson’s method among others. Resolved TPs in differential model forms can be handled with
approximate and numerical methods [21-25].
This paper therefore aims at making comparison of existing techniques for finding initial
basic feasible solution and apply modified Vogel approximation method in determining initial
basic feasible solutions so as to determine the optimal solution to any given balanced TP.
2. MATERIALS AND METHODS
For the purpose of this paper, the table below gives simplified data structure obtained from
the cement factory with three sources and four destination centres without service level
requirements. The following are considered.
There are three sources (lines 1, 2 and 3) and four destinations centres (South-South, Lagos,
Ogun, other South west states) represented by A, B, C and D respectively.
All the mentioned routes in this work are always accessible.
Movement of cement products are always from the sources to the specified destinations.
The same means of transportation of the products and constant speed are allowed.

Mathematically, we state TP compactly as given below:
∑ ∑
subject to:
∑
∑
, and
where is the capacity of supply at source , is capacity of demand at destination ,
is the amount shipped from source to destination , and ∑ ∑ is the total
shipping cost and it is non-negative. ∑ ∑ is the condition for existence of
feasible solution for standard TP. In other words, total units demanded must match total units
supplied. A balanced transportation problem having sources and destinations is usually
represented in tabular form as shown below:

4. DISCUSSION OF RESULTS, CONCLUDING REMARKS, AND
RECOMMENDATIONS
Table 7 shows the result for selected existing approaches available for solving balanced
transportation problem and their order of efficiency. MVAM is applied as well as other
existing methods for solving balanced transportation problem and compared the efficiency of
the methods at reducing total cost using the same case study. From the analysed data in Table
7, it is obvious that the MVAM gives better improvement than any other selected techniques
in determining the initial basic feasible solution (IBFS) in terms of reduction in total cost of
production in the cement factory. The results of the solution obtained in Table 7 was further
justified and validated using windows version 2.00 Tora package. The use of the modified
VAM for solving transportation problem gives a systematic and transparent solution when
compared with other existing methods. Thus for more scientific transportation problem, the
modified VAM gives a better result. Hence the modified VAM guarantees optimal solution.
The researcher, therefore, recommends that the modified VAM should be adopted and
encouraged by companies, producers and other agencies involved in transportation business.
The researcher also recommends further research in this area
