The multi-attribute group decision making (MAGDM) problem has received considerable attention in the decision analysis field and fruitful achievements have been reported in the literature. This paper focuses on the MAGDM in which the subjective absolute judgement on alternatives with respect to evaluating attributes are represented by fuzzy numbers. This paper employs the consensus degree to me...

How to quantitatively compare the performance of different algorithms is one of the most important issues in multi-objective optimization. There are a number of metrics for evaluating the performance of a multi-objective optimizer that approximates the whole efficient front. However, for evaluating the quality of a preferred subset of the efficient front, the existing metrics are inadequate. In...

Multi-criteria decision-making/analysis is a vast field designed for solving decision-making problems. Due to the widespread use of many relevant MCDA/MCDM approaches and their frequent appearance in scientific papers, there particular gap regarding comprehensive software that should have components. Therefore, this paper proposes flexible library written Python 3 multi-criteria analysis/decisi...

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...

this paper proposes a new mathematical model for designing and planning postal parcels carriage and postal networks. the objective of postal network designing is to determine the location, size and connection between the postal stations in a city, province or country. in this paper, a kind of multiple locations-allocations hub problem with limited capacity in collecting, distributing and broadc...
