Dynamic Supplier Selection and Its Optimal Strategy Considering Full Truck Load and Fuzzy Demand Using Fuzzy Expected Value Based Programming

Purnawan Adi Wicaksono

Abstract

In this paper, we propose a linier integer optimization with fuzzy parameter to solve a dynamic supplier selection problem with uncertain demand. The uncertain demand is approached by using fuzzy variable. A fuzzy expected value based linier programming is used to solve the corresponding optimization problem where the objective function is minimizing the total cost and one of the constraints is fuzzy demand. Some numerical experiments have been conducted to evaluate and analyse the model. The proposed model can be used to determine the optimal supplier and the optimal product volume from the chosen supplier for each time period so that the total cost is minimized.
