Multi-converter system is mainly used in advanced automotive systems. Different converters and inverters are taking part systems to provide different voltage levels a multi-converter system. It involves constant load (CVL), power (CPL) other loads. The CPL such offers negative impedance characteristic it creates destabilizing effect on the main converter. of destabilization can be reduced by in...

The present study addresses the following question: if among a group of decision making units, the decision maker is required to increase inputs and outputs to a particular unit in which the DMU, with respect to other DMUs, maintains or improves its current efficiencylevel, how much should the inputs and outputs of the DMU increase? This question is considered as a problem of inverse data envel...

Due to the importance of supplier selection issue in supply chain management (SCM) and ,also,  the increasing tendency of organizations to their social responsibilities, In this paper, we survey the supplier selection issue as a multi objective problem while considering the factor of corporate social responsibility (CSR) as a mathematical parameter. The purpose of this paper is to design a mode...

This paper proposes a method for ranking decision making units (DMUs) using some of the multiple criteria decision making / multiple attribute decision making          (MCDM /MADM) techniques, namely, interval analytic hierarchy process (IAHP)          and the technique for order preference by similarity to an ideal solution (TOPSIS).          Since the efficiency score of unity is assigned to ...

since the 1990’s, network reliability has been considered as a new index for evaluating transportation networks under uncertainty. a large number of studies have been revealed in the literature in this field, which are mostly dedicated to developing relevant measures that can be utilized for the evaluation of vulnerable networks under different sources of uncertainty, such as daily traffic flow...

Many operations researchers know about the use of decision analysis to help decide among alternative investments (such as pharmacological research and development investments) using decision trees with chance nodes to compute expected monetary value or return on investment of different alternatives. Such an analysis often aims to maximize a single evaluation measure for a single decision maker....

This paper presents a multi-periodic, multi-echelon blood supply chain network consisting of blood donors, mobile collection units, local blood centers, main blood centers and demand points in which the local and main blood centers are subject to random failure in dispatching blood products to demand points. The problem has two objectives including minimization of the total chain costs and maxi...

Empirical research suggests that most corporate consumer affairs departments are not a part of the decision-making structure of their respective firms. The typical consumer affairs department appears to have little influence in management decisions that affect consumer satisfaction and welfare. As a result, it is of limited value for the consumer. A reason for the isolation of consumer affairs ...
