Abstract: Most of the current researches tend to consider preventive maintenance strategy as a known scheme when performing joint optimization of two-dimensional warranty period and price,ignoring the joint design of preventive maintenance strategy within warranty period.Based on the above analysis,from the perspective of the manufacturer,the two-dimensional basic warranty period,preventive maintenance strategy and product price were jointly designed and optimized.Taking into account the differences in the end age and usage of the two-dimensional warranty for customers with different usage rates,the demand model based on the two-dimensional warranty period and the warranty cost model considering the periodic preventive maintenance were built.With the goal of maximizing the manufacturer's expected profit,the basic warranty age limit and usage limit,the number and level of preventive maintenance and the price of the product were optimized.The validity of the model was verified through an example and sensitivity analysis.This research could provide theoretical and practical guidance for manufacturers to carry out joint design and optimization of two-dimensional warranty policy.
