چکیده
رقابت های بسیار شدید در بازار و نیز تقاضای متنوع مشتریان در سال های اخیر تولید کنندگان را مجبور به ارائه
محصولات خود به همراه سیاست های متفاوت وارانتی کرده است. در این میان، سیاست وارانتی تسهیم هزینه
یکی از پرکاربردترین سیاست های وارانتی می باشد. این مطالعه با هدف حداکثر سازی سود تولید کننده به
توسعه مدلی جهت تعیین قیمت بهینه وارانتی تسهیم هزینه با دوره ثابت می پردازد که در آن تولید کننده
ریسک گریز است. در طراحی این مدل، نرخ هزینه های اصلاح محصول در طول دوره وارانتی تحت تاثیر نرخ
تورم و بهره قرار دارند و نرخ شکست محصول نیز تابعی از زمان فرض شده است. با استفاده از فرایند ناهمگن
پواسان و بکارگیری تابع مطلوبیت نمایی مدل ریاضی برای حداکثر سازی معادل قطعی سود تولید کننده
ریسک گریز و تعیین قیمت بهینه وارانتی ارائه شد. در انتها به کمک یک مثال عددی و با در نظر گرفتن
عواملی مانند ترجیحات ریسک تولید کننده، پارامتر های متفاوت تابع توزیع شکست محصول، طول دوره
وارانتی، و نرخ تورم و تنزیل اعتبار سنجی مدل صورت پذیرفت

Pro-Rata Warranty pricing model with risk-averse manufacturers Mahdi Nasrollahi

چکیده [English]
Due to fierce competition and customer demand, manufacturers have started selling products with different warranty policies and pro-rata warranty is one of the most widely used warranty policy. In this paper we propose a warranty model for pro-rata, fixed period warranty policy with risk averse manufacturer that determines optimal warranty price under inflationary condition.
This model has been proposed for products with time dependent failure intensity with Non homogeneous Poisson’s process for failure intensity function, and concave utility function. Using the exponential utility function, the decision model is developed to maximize the manufacturer’s certainty profit equivalent. Risk preference model is developed to find the optimal warranty price through the use of the manufacturer’s utility function for profit. Finally, the sensitivity of the warranty price models is analyzed using numerical examples with respect to such factors as (1) the manufacturer's risk preferences, (2) product failure rate parameters, (3) warranty period length, and (4) inflation and discount rate
