in this study, an outsourcer evaluation and management system is developed for a manufacturing company by use of fuzzy goal programming (fgp). a first phase of the methodology evaluation criteria for outsources and the objectives of the company are determined. considering the fuzziness in the decision data, linguistic variables that can be expressed in generalized fuzzy number are used. the pro...

Karen Ann Quinlan and Theresa Marie Schiavo are names tied to legal controversies over the withdrawal of medical treatment at the end of life. In re Quinlan1 arose at a time when the rules for decisionmaking for incompetent patients were still unformed and inchoate. It set the framework of analysis for most of the subsequent development in the field. Schiavo,2 on the other hand, arose over a di...

Rough set concept is a methodology of information processing for relational databases. It unique uncertainty mathematics topic closely connected to fuzzy theory. When the rough combined with neutrosophic theory, an effective tool working indeterminacy arises. In this study, we defined multi-valued and matrix. Using separation measures, introduced new approach structure. We consider problem dete...

the expansion of major cities regardless of the scientific planning principles has led to theemergence of negative urban development impacts in iran such as the degradation of natural resources andvarious forms of pollution. undoubtedly, urban rivers can enhance the ecological value of the earth to anoptimal extent. however, to benefit from these potentials, appropriate planning looks inevitabl...

Multi-criteria decision making is a sub discipline of operations research that explicitly considers multiple criteria in decision making problems. Several methods have been proposed for solving multicriteria decision making problems (MCDM). The weighted sum method (WSM) is the best known and simplest multi-criteria decision making method for evaluating a number of alternatives in terms of a num...

Multi-criteria decision making is used in many areas of human activities. Each alternative in multi-criteria decision making problem can be described by a set of criteria. Criteria can be qualitative and quantitative. They usually have different units of measurement and different optimization direction. The normalization aims at obtaining comparable scales of criteria values. The normalization ...
