We derive and compute time‐dependent distributions of replacement costs under warranty over the product life cycle, both for the manufacturer and the user, under conditional pro‐rata and nonrenewing free‐replacement warranty policies. For pro‐rata warranties, the analysis is based on the joint distribution of the number of replacements and the user's cost over time. For free‐replacement warranties, distribution of the user's cost follows from the observation that replacement points outside warranty periods form a renewal process. This property is also exploited to determine the distribution of the manufacturer's cost. We apply our findings to measure the impact of product conformance quality on warranty cost distributions and find that manufacturer's cost measures are more sensitive to changes in quality than user's cost measures. © 1995 John Wiley & Sons, Inc.

Owing to quality uncertainty in manufacturing, some of the items produced can be non-conforming. When items are sold with warranty, the warranty servicing cost for non-conforming items can be high. Life testing can be used to weed out such items and reduce the warranty cost. Such testing is expensive in terms of time and money. Releasing items with no testing can result in an increased number of early failures which in turn leads to consumer dissatisfaction and affects future profits, due to a loss of consumers. We propose a new policy which involves no testing and incorporates an incentive feature to reduce consumer dissatisfaction.
