Investigating After-Sales Service agent and Consumer profit During the Basic and Extended Warranty Period with Game Theory Approach(Case study: an Agent Services for Trucks)

This study considers optimal warranty and maintenance services from service agent and consumer view points for vehicles under two dimensional warranty policy. The interactions between the agent service and consumers are modeled by estimating their profits and then are examined by game theory in the base warranty and extended warranty. Maintenance policies are performed as period preventive maintenance (PM), home and road corrective maintenance (CM). Then, the agent and the consumer’s profits are optimized and the number of period preventive maintenance (PM) and the price of warranty services are estimated by the stackelberg equilibrium. For demonstrating the applicability of this research, finally the proposed model is investigated by using of real data from a truck service agent.
