ABSTRACT

In this paper, we study dynamic pricing strategies in a dual-channel supply chain consisting of a manufacturer, a retailer and focus on the influence of the service cost parameter and channel parameter on the system. We study dynamic pricing strategy by using the limited rational method. The complex dynamic phenomena, such as the bifurcation and chaos are analyzed through bifurcation diagrams and the largest Lyapunov exponent. The results show that in the dynamic model, the higher adjustment parameter can make the system lose its stability, then appear period doubling bifurcation. The higher service cost parameter can make the long-term average profit reduced.
