FFLP problem with symmetric trapezoidal fuzzy numbers [PDF]

open access: yesDecision Science Letters, 2015
The most popular approach for solving fully fuzzy linear programming (FFLP) problems is to convert them into the corresponding deterministic linear programs. Khan et al. (2013) [Khan, I. U., Ahmad, T., & Maan, N. (2013).

Fuzzy Linear Programming Based on Fuzzy Functions

open access: yesIFAC Proceedings Volumes, 1981
Abstract Linear programming problems with fuzzy parameters have been formulated by fuzzy functions. The ambiguity considered here is not randomness, but fuzziness which is associated with the lack of sharp transition from membership to nonmembership. Parameters on constraint and objective functions are given by fuzzy sets.

Fuzzy stochastic inventory model for deteriorating item [PDF]

open access: yesYugoslav Journal of Operations Research, 2017
A multi item profit maximization inventory model is developed in fuzzy stochastic environment. Demand is taken as Stock dependent demand. Available storage space is assumed to be imprecise and vague in nature. Impreciseness has been expressed by
