Modeling capacitated location-allocation problem with fuzzy demands

In order to model capacitated location-allocation problem with fuzzy demands, three types of fuzzy programming models - fuzzy expected cost minimization model, fuzzy alpha-cost minimization model, and credibility maximization model - are proposed according to different decision criteria. For solving these models, some hybrid intelligent algorithms are also designed. Finally, several numerical experiments are presented to illustrate the efficiency of the proposed algorithms.
