in this paper imprecise target models has been proposed to investigate the relation between imprecise data envelopment analysis (idea) and mini-max reference point formulations. through these models, the decision makers' preferences are involved in interactive trade-off analysis procedures in multiple objective linear programming with imprecise data. in addition, the gradient projection type me...

A software called EM Workshop has been developed to make easier the creation of interactive illustrations for web-based electromagnetics courses. The Workshop uses a high-level object-oriented programming model so that it can be easily adapted or complemented by the user. The definitive goal of EM Workshop is the availability for the educational community of a tool which allows the creation of ...

This paper deals with priority based fuzzy goal programming approach for solving multi-objective linear fractional programming problem. In the model formulation of the problem, we construct the fractional membership functions by determining the optimal solution of the objective functions subject to the system constraints. The fractional membership functions are then transformed into equivalent ...
