Because the purchasing department can play a key role in cost reduction, supplier selection and order allocation are the most important functions of purchasing management. In view of its complexity, it will be focused especially on the final selection stage that consists of determining the best mixture of suppliers and allocating orders among them so as to satisfy different purchasing requirements. In recent years, many researchers used new integrated models for supplier selection and order allocation. They combine multi-criteria approaches such as AHP/ANP and linear programming (LP), mixed integer programming (MIP), non-linear programming (NLP), mixed integer non-linear programming (MINLP) and goal programming (GP) with different achievement scalarizing functions. In this chapter, after the stages of supplier selection process are explained, these new integrated models are introduced and their constraints, variables, and goals/objectives of these models are explained in detail. Then the solution methods of these integrated models are given. Finally, different integrated models are compared by considering their advantages and disadvantages.

An integrated model based on ANP method which contains three major criteria, thirteen sub-criteria and thirty six factors was developed to evaluate urban regeneration project plans. To improve the traditional ANP method, a non-linear Programming equation which can be solved by the PS method was used to measure the inconsistency as well as to calculate the priorities in the pair-wise comparison stage of ANP. In addition, a DEMATEL method was employed to analyze the interdependencies of criteria/factors comprehensively. Five alternative plans of an urban regeneration project were adopted to test the effectiveness of the developed model. It was found the integrated model was feasible and effective to solve the problem of evaluation of the urban regeneration project plans.

In deregulated power markets, Independent System Operators (ISOs) maintains adequate reserve requirement in order to respond to generation and system security constraints. In order to estimate accurate reserve requirement and handling non-linearity and non-convexity of the problem, an efficient computational framework is required. In addition, ISO executes SCUC in order to reach the consistent operation. In this paper, a novel type of application which is Benders decomposition (BD) and Mixed integer non linear programming (MINLP) can be used to assess network security constraints by using AC optimal power flow (ACOPF) in a power system. It performs ACOPF in network security check evaluation with line outage contingency. The process of solving modified system would be close to optimal solution, the gap between the close to optimal and optimal solution is expected to determine whether a close to optimal solutionis accepetable for convenientpurpose. This approach drastically betters the fast computational requirement in practical power system .The numerical case studies are investigated in detail using an IEEE 118-bus system.
