In credibility theory, variance is usually used as a measure of the variation of a possibility distribution about the expected value. Since the variance is defined via nonlinear fuzzy integral, its computation is difficult for general fuzzy variables. To avoid this difficulty, this paper defines the spread of a fuzzy variable based on Lebesgue-Stieltjes (L-S) integral. Our approach is to find an "average...
This paper attempts to present a new class of fuzzy two-stage supply chain problem with minimum risk criteria in the sense of value-at-risk (VaR), in which the transportation cost coefficients and the demands are characterized by fuzzy variables with known possibility distributions. Since the fuzzy parameters has infinite supports, the conventional optimization algorithms cannot be used directly to...
Two-stage fuzzy minimum-risk problems (FMRPs) include fuzzy variable parameters defined through a possibility distribution, they are inherently infinite-dimensional optimization problems that can rarely be solved directly. Therefore, algorithms to solve such optimization problems must rely on intelligent computing as well as approximating scheme, which results in approximating finite-dimensional FMRPs...
Since fuzzy programming with recourse problems includes fuzzy variable parameters defined through a possibility distribution, it is inherently infinite-dimensional optimization problems that can rarely be solved directly. Therefore, algorithms to solve such optimization problems must rely on intelligent computing as well as approximating scheme, which result in approximating finite-dimensional optimization...
