Warranty Costs: An Age-Dependent Failure/Repair Model
نویسندگان
چکیده
An age-dependent repair model is proposed. The notion of the “age” of the product and the degree of repair are used to define the virtual age of the product. The virtual failure rate function and the virtual hazard function related to the lifetime of the product are discussed. Under a non-homogeneous Poisson process scenario the expected warranty costs for repairable products associated with linear pro-rata, non-renewing free replacement and renewing free replacement warranties are evaluated. Illustration of the results is given by numerical and graphical examples.

Optimal overhaul–replacement policy for a multi-degraded repairable system sold with warranty
In this research, we study an optimal overhaul–replacement policy of a multi-degraded repairable system sold with a free replacement warranty. In the proposed replacement policy, a maintenance action and failure are dependent on a system degradation level and the system age, and hence the replacement model will provide more effective maintenance decisions. Failure of the system is modeled using...

متن کاملWarranty Servicing with Imperfect Repair for Products Sold with a Two-Dimensional Warranty
In this paper, a new servicing strategy with imperfect repair is defined and studied for the manufacturer of a product sold with a two-dimensional warranty. The strategy is based on a specified region of the warranty defined in terms of age and usage, with the first failure in the region rectified by an imperfect repair and all other failures being minimally repaired. Product failures are model...
متن کاملLast time buy decisions for products sold under warranty
Manufacturers supplying products under warranty need a strategy to deal with failures during the warranty period: repair the product or replace it by a new one, depending on e.g. age and/or usage of the failed product. An (implicit) assumption in virtually all models is that new products to replace the failed ones are immediately available at given replacement costs. Because of the short life c...
