Coordination of incentive conflict based on Gery-Stackelberg model under the main manufacturers-suppliers model

Main manufacturer-supplier model is widely applied in the R&D procedure of complex products such as plane. Because of the uncertainty in the R&D, the effort of the suppliers has an important effect on it. During the procedure, there will generate a lot of inadequacy of information, grey number is an important tool for the estimation of pay-off matrix. Considering the dynamic interaction between the main manufacturers and suppliers, with the main manufacturers as leader and suppliers as follower, this paper establishes a Grey-Stackelberg model to analyze the best change of the incentive strategies of the main manufacturers and the effort strategies under incentive-conflict of suppliers under the uncertain environment. The results show that the main manufacturer can increase its benefit without damage the interests of suppliers by controlling the fixed incentives.
