Abstract: Warranty service is a contract between manufacture and consumer, which is usually applied to sales promotion. The price is related to warranty length of product. Considering the reality, based on the consumer utility theory, assuming pro-rata warranty policy and the product failure with Index distribution function, in order to maximum manufacture’s revenue, It studies the differential pricing issues for the product with multiple warranty. It analyzes the optimal combinational strategy with pricing and warranty, and employs optimization theory and method to derive the optimal pricing policy, and verifies the validity of the model through the numerical analysis and analyzes the difference between differential pricing and single pricing. Then it analyzes the impact of the consumer shift flexibility to the benefits of manufacturers.
