Abstract
As Crosby notes, the most companies spend 15 to 20% of their sales dollars on quality costs. Generally themost effective way to manage quality costs is to avoid having defects in the first place.In this paper we have studied about the repair(service) problem of domestic gas boiler within warrantyperiod. We develop a system, which man could find the cause of the problem at an early stage and coulddevise a countermove to the problem under supposing that the service(repair) rate follows exponentialdistribution and the product is manufactured lot-for-lot continually.Using the developed early sensing system. it is expected to improve the reliability of the product, to saveexpenses of company and to improve customer’s satisfaction. And the system will be expended to incorporateinformation technology, which can detect the repair rate automatically.
