Based on random fuzzy theory, this paper presents a new class of two-stage random fuzzy programming model, and gives three solution concepts, which are wait-and-see solution, here and now solution and expected value solution. Since the value of information and uncertainties plays an important role in the studies of uncertainty optimization problem, this paper gives two optimal indexes based on the...
The paper is concerned with finding the refined bounds on the value of fuzzy solution to fuzzy programming prob- lem. In this paper we first present the definitions which are the sum of pairs expected value (SPEV), the expected value of the reference scenario (EVRS)and the expectation of pairs expected value (EPEV), and obtain the value of fuzzy solution (VFS) defined by difference between the re-...
Based on fuzzy random theory, a new class of two-stage fuzzy random model is studied in this paper. In case of general recourse matrix, some fundamental properties of two-stage fuzzy random programming are discussed, including the convexity of feasible set as well as convexity of objective function.
