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 ...

In this study we propose an approach of quantifying the risks of misinforming and malfunctioning aiming to assess the quality of a warranty policy. We identify the “quality” of a warranty policy as an integral measure, based on the balance between two types of warranty – the warranty of malfunctioning and warranty of misinforming. This measure is represented in terms of the length of the warran...

currently, a large number of products are being sold with warranty policies. pro-rata warranties are relatively a complex concept. this paper focuses on developing a new pro-rata warranty policy. in this model components of the product are grouped into two disjointed sets, failures of components belonging to set one are covered by prw warranty and those components that belonging to set two are ...

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...
