An optimal control method for fuzzy supplier switching problem

摘要

In a very recent paper, we have established a fuzzy supplier switching model with asymmetric information and apply the variational method to solve the proposed model. In this paper, we further investigate the proposed fuzzy supplier switching model and convert it into a common optimal control problem. Then the optimal supplier switching strategy can be derived by a new method called Pontryagin's maximum principle which is an efficient tool to deal with the optimal control problem. The optimal supplier switching strategy can be obtained without considering the inflection point of the constraint condition and the formations of distribution function and density function.
