| The perishable products prices will drop significantly after specified periods, for example a season. Hence, over-production or shortage of such products is associated with loss of profit, respectively. In this paper, optimal aggregate production planning, is determined for the production of perishable products such as seasonal clothing, New Year gifts, calendars and almanacs by postponement policy in uncertainty conditions. The production process for these products is proposed to be divided into two phases, with applying the postponement concept. So, there are three production activities, including direct production, production of semi-finished products, and final assembly. A robust optimization model to solve aggregate production planning for these products will be developed, and the set of data will be used for model validation. The paper model can be used to solve real-world problems of aggregate production planning in an uncertain condition. | ||

| چکیده [English] | ||
| قیمت محصولات فاسدشدنی پس از دوره‌ای مشخص برای مثال یک فصل، به‌طور مؤثر کاهش می‌یابد؛ بنابراین، تولید اضافی یا کمبود این محصولات به‌ترتیب همراه با زیان یا ازدست‌دادن سود است. این پژوهش برنامه‌ریزی تولید ادغامی بهینه را برای تولید محصولات فاسدشدنی مانند پوشاک فصلی، هدیه‌های سال نو، تقویم‌ها و سررسیدها با استفاده از سیاست تعویق در شرایط عدم قطعیت تعیین می‌کند. پیشنهاد شده است فرایند تولید این محصولات با اعمال مفهوم تعویق به دو مرحله تقسیم شود. درنتیجه، سه فعالیت تولیدی شامل تولید مستقیم، تولید محصول نیمه‌ساخته و مونتاژ نهایی وجود دارد. مدل بهینه‌سازی استوار برای حل برنامه‌ریزی تولید ادغامی این محصولات توسعه داده شده و از مجموعه‌ای از داده‌ها برای اعتبارسنجی مدل استفاده شده است. می‌توان از مدل پژوهش برای مسائل واقعی برنامه‌ریزی تولید ادغامی کارخانه‌ها در شرایط عدم قطعیت به‌خوبی استفاده کرد. | ||
