Aiming to reduce the warranty cost, we put forward a new warranty strategy of two-dimensional (2D) warranty products. In this strategy, the incomplete preventive maintenance and minimal repair are proposed where the preventive maintenance is further divided by the degree of maintenance, and all other failures are repaired minimally. Preventive maintenance of different degree is put forward by the manufacturer and the user, respectively, and the repair factor is used to distinguish the different degree of maintenance. We establish model of warranty cost based on reliability theory and propose a method to solve the model. Finally, the validity of this model is proved by a numerical example, and the sensitivity analysis is carried out.
