Two-dimensional product warranty cost model under preventive maintenance time constraints

Providing high-quality product warranty service is an important part of the current competition among manufacturers for customers. On the basis of current warranty service, providing reasonable warranty service to customers more closely and practically is a problem that manufacturers must consider. On the basis of existing literature and considering the actual situation of manufacturers and customers, the time constraints of preventive maintenance in warranty service are proposed for the first time. Under the incomplete preventive maintenance strategy, the time of preventive maintenance during the warranty period is limited, and a two-dimensional product maintenance cost model under the time constraint is established to determine how to carry out preventive maintenance to obtain the ideal maintenance cost. The validity of the model is verified by an example, providing a basis for product two-dimensional warranty service decision-making. © 2019 Totem Publisher, Inc. All rights reserved.
