this paper presents a fuzzy goal programming (fgp) methodology for solving bi-level quadratic programming (blqp) problems. in the fgp model formulation, firstly the objectives are transformed into fuzzy goals (membership functions) by means of assigning an aspiration level to each of them, and suitable membership function is defined for each objectives, and also the membership functions for vec...

supplying required human resource is one of the strategic goals of an organization. therefore, organizations plan and predict the required human resources in order to prevent this problem. present study using practical approach seeks to assist organizations to achieve their various goals in human resources planning. the designed model in this study clarifies vague, inaccurate, and fuzzy express...

in this paper the real-world occurrence of the multiple-product multiple-constraint single period newsboy problem with two objectives, in which there is incremental discounts on the purchasing prices, is investigated. the constraints are the warehouse capacity and the batch forms of the order placements. the first objective of this problem is to find the order quantities such that the expected ...

universities have a magnificent role in the sustainable development of their country and international scientific production of their country. purpose of this paper is expansion of using balance scorecard in universities in order to improve performance of universities in learning and educating. the balanced scorecard (bsc) is an extensively adopted performance management framework in a lot of o...

Abstract It is the purpose of this article to introduce a linear approximation technique for solving a fractional chance constrained programming (CC) problem. For this purpose, a fuzzy goal programming model of the equivalent deterministic form of the fractional chance constrained programming is provided and then the process of defuzzification and linearization of the problem is started. A sam...
