“…Increased interest in issues of reliability, quality and warranty can be observed in the furniture industry (Ratnasingam et al, 1997;Gremyr et al, 2003;Smardzewski, 2005Smardzewski, , 2009; Kłos and Fabisiak, 2010). Reliability is an essential feature determining the commercial success of a product and it is a signifi cant element in the competitive strategy of the enterprise (Sander and Brombacher, 2000;Murthy and Djamaludin, 2002;Murthy, 2006;Murthy, 2007;Fabisiak, 2013a, 2013b;Ojurović et al, 2013). It is of importance both for furniture producers (Vickery et al, 1997) and consumers (Udell and Anderson, 1968;Sinclair and Hansen, 1993;Pakarinen and Asikainen, 2001; Ratnasingam, 2003;Chien et al, 2005;Knauf, 2015).…”

“…Murthy et al (2008Murthy et al ( , 2009 have dealt with reliability decision making during the 140 JAMR 10,1 front-end (or feasibility) and the design and development stages of new product development. Murthy (2007) has given a brief overview of reliability as well as warranty and discussed some new issues and the challenges for future research. Doganaksoy et al (2006) have described methods of implementing quality control techniques for various processes in business enterprises and to improve reliability of equipment, based on analysis of data pertaining to warranty.…”

“…A warranty of any type, since it involves an additional service associated with a product, will lead to potential costs to the manufacturer beyond those associated with the design, manufacture and sale of the product. The warranty servicing costs may vary from 2 to 10 percent of sale price depending on the product and the manufacturer ( Murthy, 2007). The warranty cost strongly depends on the reliability of the product which in turn depends upon several factors, some of which are controlled by the manufacturer, such as the decisions made during the design and development stage.…”

Purpose-The purpose of the paper is to develop a conceptual framework that integrates the technology and commercial issues early at the design stage to minimize warranty costs in the most effective and efficient manner and also to develop a model for optimization of warranty with specific focus on reliability and warranty policies. Design/methodology/approach-The critical issues in warranty are addressed which affect the warranty cost. An optimization model to achieve multiple goals like minimization of the warranty cost and improving the reliability of the product is developed using genetic algorithm as a solution methodology. The model is illustrated with a real case of automobile engine. Findings-The results of the optimization show improvement in mean time between failures (MTBF) which results due to improvement in the product reliability and also the targeted warranty cost is achieved. Research limitations/implications-The model developed needs to be further extended with inclusion of additional decision variable such as support level offered and more objectives such as attractiveness of the warranty from the customer's view point and spares cost to the customer. Originality/value-The paper provides the help to the designers at the design stage to take the decisions related to warranty in deciding the warranty parameters.

The relevance of this study is determined by the fact that, in modern conditions, the manufacturers of high-tech products offer long-term warranty service for their products aiming at receiving the consumer. In turn, the frequency of warranty service depends on the probability of trouble-free operation of the product in a certain time interval. However, increasing the uptime of the products and increase the warranty period results in increased costs. Therefore, the purpose of this study is to develop a model that allows determining the impact of the following factors on the product cost: the reliability of the manufactured products and the term of their warranty. To achieve the goal of the research there has been determined the content of warranty service, has been introduced the integrated indicator of quality warranty services, and has been shown the level of products reliability as a dependence from the costs of their manufacturing and warranty service. The novelty of this study is estimation of the manufacturer's cost depending on the way of providing the warranty service, either by repair, or by complete replacement of the failed product. The research results provide competitive advantages to manufacturers of high-tech products since it enables to find the efficient period and intensity of the warranty service.
