Warranty claims and supplementary data contain useful information about product quality and reliability. Analysing such data can therefore be of benefit to manufacturers in identifying early warnings of abnormalities in their products, providing useful information about failure modes to aid design modification, estimating product reliability for deciding on warranty policy and forecasting futur...

A new maintenance policy which minimizes the total expected servicing cost for an item with two–dimensional warranty is proposed. An iterative procedure to estimate the item’s failure rate function from historical observations and an optimization algorithm based on Monte Carlo simulation are applied to obtain the best maintenance policy. Numerical examples and sensitivity analysis are presented.

We consider the problem faced by a company selling a product with warranty and under partial information about the product reliability. The product can fail from multiple failure types, each of which is associated with an inherently different repair cost. If the product fails within the warranty duration, then the company is required to pay the repair cost. The company does not know the probabi...

Hardware trends in the personal computing industry adversely impact the sale of extended warranties. Steep declines in PC prices, including the introduction of new low-priced hardware categories like netbooks, make replacing one's PC an increasingly viable alternative to paying for repairs or buying an extended warranty. Frequent improvements in PC functionality further tilt the scales in favor...

For engineering and production systems, due to the structural dependence between components, disassembly operation caused by replacement of components will affect failure degradation processes other in system. In order optimize extended warranty (EW) cost multi‐component system with dependence, this paper described modeled impact, then rate model component considering impact under EW was develo...

From large-scale aerospace systems to household appliances and other in daily life, the application of parallel is involved. A system a typical structural dependence multi-component system, addition series hybrid system. This paper takes as research object minimizes expected cost rate or maximizes availability by determining optimal two-dimensional age replacement interval. The components descr...
