Multi item inventory model include lead time with demand dependent production cost and set-up-cost in fuzzy environment [PDF]
Journal of Fuzzy Extension and Applications, 2020 In this paper, we have developed the multi-item inventory model in the fuzzy environment. Here we considered the demand rate is constant and production cost is dependent on the demand rate.

Proposed Method for Optimizing Fuzzy linear programming Problems by using Two-Phase Technique [PDF]
Iraqi Journal for Electrical and Electronic Engineering, 2010 Fuzzy linear programming (FLP ) is an application of fuzzy set theory in linear decision making problems and most of these problems are related to linear programming contains fuzzy constrains or crisp objectives function or contains crisp ...

FFLP problem with symmetric trapezoidal fuzzy numbers [PDF]
Decision 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
IFAC 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]
Yugoslav 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
