Using monitored job cycles to design and model random maintenance strategies for ensuring life-cycle reliability has been extensively researched. The heterogeneity over the life cycle ignored universally in this type of strategy. In paper, using two different areas regions that can screen reliability, were customized reliabilities warrantied products with be ensured based on heterogeneity. case...

An effective warranty servicing strategy should be made considering both warranty cost and product availability. Based on the two-dimensional free repair warranty, a strategy combining the imperfect preventive maintenance and minimal repair is proposed where the imperfect preventive maintenances are implemented in a special subregion of the warranty and all other failures are repaired minimally...

Reducing the excess costs of consumer due to timely maintenance and increasing efficiency detecting deviations in technical condition improve operational reliability is an important task improving using energy-saturated tractors domestic production. In order promptly provide initial information on degree use current state resource-determining parts assemblies, as well increase controllability a...

This study makes a first effort to understand the factors affecting customers' decisions to invoke warranties, and to distinguish this behavior from the factors affecting customer perceptions of service quality. The study context is GTE's introduction of a warranty program as part of a telecommunications repair service for small business customers. The results suggest that customer perceptions ...

Abstract Why are some contractual terms revised continuously while others stubbornly fixed? We offer an account of both change and stickiness in standard-form contracts. hypothesize that drafters (sellers) more likely to revise their standard when they have opportunity learn about the terms’ costs from experience. Consider a warranty. Offering warranty initial period will expose sellers claims ...

The objective of this study is to develop a warranty servicing strategy, based on imperfect and minimal repairs, that minimises the total warranty servicing cost. For pre-specified degrees of repair, the expected warranty servicing cost is minimised by optimally partitioning a two-dimensional rectangular warranty region into n disjoint subregions. We numerically illustrate the imperfect repair ...

Warranty data contain useful information about product quality and reliability, but they are usually coarse data because they may be aggregated, delayed, censored, missing or vague. They might, however, be the only forms of warranty data a manufacturer has, analysing such data are therefore needed and can also be of benefit to manufacturers in identifying early warnings of abnormalities in thei...
