Estimation of the Relationship between the Products Reliability, Period of Their Warranty Service and the Value of the Enterprise Cost

Abstract

The competitiveness of the manufacturer in modern conditions is determined by many factors. One of these factors is the products warranty. Nevertheless, this service considers additional manufacturing costs. The purpose of this research is to determine the dependence of the accessible reliability of products with the expenses level of the manufacturer, offering warranty services. To achieve this goal, the methods of mathematical statistics and probability theory were used. The research has determined the content of warranty service, has introduced the integrated indicator of warranty services quality, and has showed the level of products reliability as a dependence from the costs of their manufacturing and warranty service. The study results can be used by manufacturers in determining cost-effective period and depth of warranty services
