Abstract    Abstract: In recent decades, high profits of extended warranty have caused that third-party firms consider it as a lucrative after-sales service. However, customers division in terms of risk aversion and effect of offering extended warranty on manufacturers’ basic warranty should be investigated through adjusting such services. Since risk-averse customers welcome extended warranty, while the customers without taking on risk may remain at the level of basic warranty. In this paper, a multi-objective integer nonlinear programming model is presented for integrating the supply chain of after-sales services. In the suggested model, firstly strategies used by the manufacturers in the basic warranty period and the third party’s policy during the extended warranty period, including the development of a new imperfect maintenance approach, are regulated. Then, the effects of these strategies on the desirability of customers with different levels of risk-taking are analyzed. To optimize the model, the scatter search based approach was introduced for extracting set of non-dominated solutions. The results indicated that increasing level of customers’ risk-taking convinces manufacturers to diminish the basic warranty period and the third party can apply less costly preventive maintenance.

چکیده    چکیده: در طی دهه­های اخیر سود بالای وارانتی تمدیدشده باعث شده است که شرکت­های شخص ثالث آن را به‌عنوان یک خدمت پس از فروش پردرآمد مدنظر قرار دهند. با این حال تقسیم‌بندی مشتریان از دیدگاه ریسک گریزی و تاثیر پیشنهاد وارانتی تمدیدشده بر روی وارانتی پایه تولیدکننده بایستی در طی تضمین چنین سیاست­های لحاظ شود. زیرا مشتریان ریسک گریز از وارانتی تمدید شده استقبال می­نمایند و در مقابل مشتریان بدون ریسک ممکن است در سطح وارانتی پایه باقی بمانند. در این مقاله یک مدل چندهدفه غیر خطی عددصحیح برای یکپارچه­سازی­ زنجیره تامین خدمات پس ازفروش ارائه می­شود. در مدل پیشنهادی ابتدا استراتژی­های تولید­کننده در دوره وارانتی پایه و سیاست­گذاری­های شخص ثالث در طی دوره وارانتی تمدیدشد، از جمله توسعه یک رویکرد نگهداری و تعمیرات ناقص جدید، تنظیم می­شود. سپس تاثیر این استراتژ­ی­ها بر مطلوبت مشتریان با دارای درجه ریسک­پذیری متفاوت بررسی خواهد شد. به­منظور بهینه­سازی مدل، روش حلی مبتنی بر رویکرد جست­وجو پراکندگی برای استخراج مجموعه­ جواب­های غالب معرفی می­گردد. نتایج نشان داد که افزایش سطح ریسک­پذیری مشتریان تولید­کننده را مجاب به­کاهش طول دوره وارنتی پایه می­کند و شخص ثالث می­تواند از نگهداری و تعمیرات پیشگیرانه کم­هزینه­تری استفاده نماید.
