چکیده | ||
امروزه تعداد بسیار زیادی از محصولات با وارانتیهای گوناگون فروخته میشوند که در این میان وارانتیهای تسهیم هزینه و مدلسازی شکستها در طول دورۀ وارانتی و هزینههای این سیاست، پیچیدگیهای زیادی دارند. در این مقاله نوعی مدل جدید سیاست وارانتی PRW توسعه داده شده است که در آن، خرابی تعدادی از قطعات محصول مشمول وارانتی میشود و تعدادی از قطعات نیز تحت پوشش وارانتی قرار ندارند. بهمنظور ارائۀ این سیاست جدید، دو رویکرد جداگانه طراحی شد که در هر رویکرد چگونگی برآورد نرخ شکست محصول متفاوت است. مدل پیشنهادی به تولیدکننده کمک میکند تا در صورت بهکارگیری سیاست پوششندادن برخی قطعات، برآورد دقیقی از هزینههای مورد انتظار داشته باشد و قیمت وارانتی را بر این اساس تعیین کند؛ در نتیجه خریدار نیز از کاهش هزینههای مورد انتظار وارانتی و بهتبع آن کاهش قیمت وارانتی سود خواهد برد. در نهایت، مدلهای برآورد هزینههای وارانتی محصول در طول دورۀ طراحی و با استفاده از مثال عددی اعتبارسنجی شده است. | ||

چکیده [English] | ||
Currently, a large number of products are being sold with warranty policies. Pro-rata warranties are relatively a complex concept. This paper focuses on developing a new Pro-rata warranty policy. In this model components of the product are grouped into two disjointed sets, failures of components belonging to set one are covered by PRW warranty and those components that belonging to set two are not covered under warranty. In order to design the new policy, two different approaches were designed that in any approach the product failure rates are estimated separately. The proposed model helps manufacturer to have a precise estimate of the expected costs and determine the warranty price based on this estimation. As a result of reduction of expected warranty costs and consequently the price, the customer will also benefit. Finally, the sensitivity of warranty model is analyzed with a numerical example. | ||
