Purpose: Evaluation and selection of efficient suppliers is one of the key issues in supply chain management which depends on wide range of qualitative and quantitative criteria. The aim of this research is to develop a mathematical model for evaluating and selecting efficient suppliers when...

Rank-ordering of individuals or objects on multiple criteria has many important practical applications. A reasonably representative composite rank ordering of multi-attribute objects/individuals or multi-dimensional points is often obtained by the Principal Component Analysis, although much...

The best-value system is viewed as a balance between the consideration of price and qualifications. The low-bid ethod fails to serve the public interest because the lowest offer may not result in the lowest overall cost to the public. Best-value contracting strategy aims at using price and other...

Consciousness affects managerial decision making in the real world. In today's dynamic and complex world, managers have to evaluate multiple criteria and various constraints associated with them. An attempt is made in this paper to rank managers into various consciousness levels based on the...

In this paper we introduce a quasi-concave nonlinear multiple attribute utility function (MAUF) to rank multiple criteria alternatives. We demonstrate that the quasi-concave MAUF (QCMAUF) is more general and flexible than additive, multiplicative, and multilinear MAUFs. New definitions of...
