Fuzzy Multi-Objective Optimization for the Allocation of Multinational Production Resources Considering Import Quota

This paper develops a global supply chain network model considering global factors such as exchange rate, tariff and import quota. The model is a fuzzy multi-objective mixed integer programming model which aims to maximize manufacturer's profit and delivery quality of suppliers. We further discuss how to transform the fuzzy multi-objective programming model into a single-objective linear programming model. We use the interactive fuzzy multi-objective linear programming method to solve the model, which provides an interactive framework for decision makers and facilitates the decision-making process under the fuzzy environment. Additionally, the framework enables decision makers to interactively change membership functions to achieve the most satisfactory solution. Finally, an illustrative example verifies the feasibility and validity.
