They can also be caused by two types of human 7 factors. On the one hand, consumers might claim warranty due to misuse and/or failures caused by other human 8 factors. Such claims might account for more than 10% of all rep...

This article presents a review of the issues associated with a manufacturer’s pricing strategies in a twoechelon supply chain that comprises one manufacturer and two competing retailers, with warranty period-dependent demands. The manufacturer, as a Stackelberg leader, specifies wholesale prices to two competing retailers who face warranty period-dependent demand and have different sales costs....

Recent years have seen a strong trend toward outsourcing warranty repair services to outside vendors. In this paper we consider the problem of dynamically routing warranty repairs to service vendors when warranties have priority levels. Each time an item under warranty fails, it is sent to one of many service vendors for repair. Items covered by higher priority warranty receive higher priority ...

Modern avionics can account for around 30% of the total cost aircraft. Therefore, it is essential to reduce operational during a lifetime. This article addresses critical scientific problem creating appropriate maintenance models digital systems that significantly increase their effectiveness. In this research, we propose lifecycle equations select best option avionics. The proposed consider pe...

A martingale estimator for the expected discounted warranty cost process of a minimally repaired coherent system under its component level observation is proposed. Its asymptotic properties are also presented using the Martingale Central Limit Theorem.

This paper presents a quantitative solution that minimizes the life cycle cost of a product by developing an optimal product validation plan. Dependability constitutes an integral view of a product’s reliability, availability, maintainability, quality, and safety. The methodology developed in this paper incorporates several dependability-related activities into a comprehensive probabilistic cos...
