In view of the problem that the availability of two-dimensional warranty products is difficult to meet the actual needs of users during the warranty period, on the basis of incomplete preventive maintenance, this paper uses the accelerated failure time (AFT) model to describe the failure rate form of products, constructs the two-dimensional warranty product availability model and gives an effective solution. On this basis, taking the maximum availability of two-dimensional warranty products as the optimization objective, the optimal preventive maintenance interval and warranty period optimization scheme are calculated. Finally, the validity and accuracy of the model are verified by an example, which provides a scientific basis for manufacturers to formulate two-dimensional product warranty strategy.
