Global Production Planning with Fuzzy Exchange Rates
نویسنده
چکیده
This paper presents a new two-stage fuzzy optimization method for global production planning problem, in which exchange rates are characterized by fuzzy variables with known possibility distributions. For this purpose, we first introduce the measure generated by credibility distributions. Then we use the generated measure to define the Lebesgue-Stieltjes (L–S) integral of function of fuzzy variables. When demands are deterministic, we decompose the feasible regions into several subregions, and discuss the solution properties of the proposed optimization model in each subregion. According to the obtained theoretical results, we design a decomposition solution method for the proposed production planning problem. Finally, one numerical example is presented to demonstrate the developed new optimization method. c ©2014 World Academic Press, UK. All rights reserved.

Adaptive aggregate production planning with fuzzy goal programming approach
Aggregate production planning (APP) determines the optimal production plan for the medium term planning horizon. The purpose of the APP is effective utilization of existing capacities through facing the fluctuations in demand. Recently, fuzzy approaches have been applied for APP focusing on vague nature of cost parameters. Considering the importance of coping with customer demand in different p...

Robust supplier selection problem, in a scenario-based approach has been proposed, when the demand and exchange rates are subject to uncertainties. First, a deterministic multi-objective mixed integer linear programming is developed; then, the robust counterpart of the proposed mixed integer linear programming is presented using the recent extension in robust optimization theory. We discuss dec...
متن کاملSolution of fuzzy integrated production and marketing planning based on extension principle
The integration of production and marketing planning is crucial in practice for increasing a firm’s profit. However, the conventional inventory models determine the selling price and demand quantity for a retailer’s maximal profit with exactly known parameters. When the demand quantity, unit cost, and production rate are represented as fuzzy numbers, the profit calculated from the model should ...
