Repairing Infeasibility in Fuzzy Goal Programming
نویسندگان
چکیده
The problem of solving a multi-objective programming problem, by assuming that the decision maker has fuzzy goals for each of the objectives, is addressed. In this case a fuzzy goal programming problem has to be solved. But when we have several objectives it can be a difficult task for the decision maker to determine coherent aspiration levels, so it is possible that the tolerance thresholds be inconsistent with each other, therefore obtaining an infeasible problem. We present a procedure in order to repair the infeasibility. We rebuild the unattainable fuzzy goals keeping their relaxation levels as small as possible while maintaining, at the same time, a good balance vis-à-vis the degree of achievement of the others goals. Keywords—, Fuzzy goal programming, Goal programming, Infeasibility, Multi-objective programming.

A new approach to rank the decision making units in presence of infeasibility in intuitionistic fuzzy environment
Data envelopment analysis (DEA) is a linear programming based methodology to determine the relative performance efficiencies of homogeneous decision making units (DMUs). In real world applications, some input and output datas do not possess crisp/fuzzy essence but they possess intuitionistic fuzzy (IF) essence. So, in this study, we develop an IF BCC (IFBCC) and an IF super efficiency BCC (IFSE...

متن کاملA production-repairing inventory model with fuzzy rough coefficients under inflation and time value of money
In this paper, a production-repairing inventory model in fuzzy rough environment is proposed incorporating inflationary effects where a part of the produced defective units are repaired and sold as fresh units. Here, production and repairing rates are assumed as dynamic control variables. Due to complexity of environment, different costs and coefficients are considered as fuzzy rough type and t...
