Outline of Final Research Achievements

In this research, we have considered multiobjective production and distribution network optimization problems in fuzzy stochastic environments. We have formulated multi-objective problem in which the coefficients of the problems, such as production costs, transportation costs and demands, are represented with fuzzy random variables and random fuzzy variables, and so on. We have defined the concepts of new optimal solutions which take account of the ambiguity contained in the knowledge of experts as well as the randomness related to stochastic factors, on the basis of both the possibility theory and probability theory. We developed efficient algorithms for obtaining the newly defined solutions.
