Supplier Selection and Order Allocation Models in Supply Chain Management: A ...IJERA Editor
Supplier selection decisions are an important component of production and logistics management for many
firms. Such decisions entail the selection of individual suppliers to employ and the determination of order
quantities to be placed with the selected suppliers. This paper reviews supplier selection and order allocation
models based on an extensive search in the literature (170 paper during 2000-2016) and tries to show their
contribution to supply chain management. After discussing different methods and their applications, the most
prevalently used approaches and criteria are presented. In the second step, different attributes of these papers are
defined and finally issues for future research are recommended
Supplier ranking and selection in a bakeryIOSR Journals
Supplier evaluation and selection is a fundamental problem in supply chain management. Many
companies may not know how to evaluate proposed suppliers to integrate the different criteria upon which they
want to make their decision. A number of techniques have been employed to solve this problem but were not
able tosufficiently incorporate qualitative criteria into consideration for estimation of their alternatives.
A multi-criteria decision-making (MCDM) methodology, the Analytical Hierarchy Process (AHP), which takes
into consideration both quantitative and qualitative criteria, was used to evaluate three suppliers of improvers
(a major ingredient) for bread production in a bakery,UIB, in southwest Nigeria. This method uses a ranking
scale when comparing alternatives. A consistency ratio is estimated when data have been collected to check for
the consistency of judgments to ensure an accurate result is obtained with the method.
It was discovered that Supplier C adds more value to UIB because it had the highest priority weight of 0.346,
although it was keenly followed by suppliers B and C with weights 0.336 and 0.317 respectively.
Results showed that each supplier fared well under one criteria or the other and there was a generally
good performance from all suppliers.

A Supplier Selection Criteria Using Boolean Association Rule MiningWaqas Tariq
Supplier selection is a multi criteria problem, nowadays it is very difficult to select a good supplier among huge number of suppliers. To select a good supplier among numbers of supplier we include both qualitative and quantitative factors. In this project we use Boolean association rule mining to count the support and confidence of suppliers which is based on different qualitative and quantitative criteria of suppliers. These projects generate a rule with some support and confidence and select the supplier who satisfied the criteria condition (Boolean association rule).

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

In most cases, construction organizations are not proficient at identifying
the capabilities of their suppliers.
They sometimes rationalize supplier decisions based on convenience.
They wait too late to assess the value added by suppliers and service
providers.
They do not recognize the impact of the economic changes on bulk
materials prices.
12. Barriers to Supply Chain Management

16. SUPPLIER EVALUATION SYSTEM
The three general types of supplier evaluation systems used today are
Categorical method,
Cost-Ration method,
Linear averaging method.
The guiding factor in deciding which system is best is;
•Ease of implementation
•Overall reliability of system.
It should be noted that implementation of the results is the matter of the buying
organization’s judgment.

B Neutral (0) Good (+1) Good (+1) (+2)
C Neutral (0) Good (+1) Neutral (0) (+1)
Example of categorical method
17
The buyer develops a list of performance factors for each supplier
track of each area by assigning a “grade” in simple terms such as:
“good,” “neutral,” and “unsatisfactory.”

Total lot received 58 40
Service Rating 89.7 95.0
Price (weight = 15)
Lowest price 75 75
Price submitted 75 82
Price Rating 100 91.5
Total Performance Rating 89.5 90.7
This method is the most commonly
used evaluation method.
Specific quantitative performance
factors are used to evaluate supplier
performance.
The most commonly used factors
are quality, service (delivery) and
price
Linear averaging method

Relative Importance Index (RII)
Is the process where weight is given to each type of response as per the judgment of
the user. In this case;
Strongly Disagree = 1
Disagree = 2
Undecided = 3
Agree = 4
Strongly Agree = 5
Then RII for each option is calculated using the equation;
RII = (W1*n1 + W2*n2 + ….) / A*N
Where W = Weight of the option as decided by user,
n = Number of responses under each option,
A = Highest weight given and
N = Total number of respondents.

While selecting supplier construction industry looks for consistent performance in terms of
quality and on time delivery.
Client expect their suppliers to be responsive.
Supplier should have a good testing capability to finish project as per established QA & QC.
Frequent design changes the supplier and subcontractors are informed well in advance.
Imposing penalty is the best way for preventing wastage at site.
