چکیده
در این پژوهش، برنامه ریزی تولید ادغامی چند کارخانه ای برای تولید محصولات فاسد شدنی مانند هدیه های
سال نو، تقویم ها و سررسید ها با استفاده از سیاست تعویق در شرایط عدم قطعیت، تعیین می شود. فرایند تولید
این محصولات با اعمال مفهوم تعویق، به دو مرحله ی تولید محصول نهایی و نیمه ساخته تقسیم می گردد.
بنابراین سه فعالیت تولیدی شامل تولید مستقیم، تولید محصول نیمه ساخته و مونتاژ نهایی وجود دارد. همچنین،
یک مدل بهینه سازی استوار جهت حل برنامه ریزی تولید ادغامی این محصولات، گسترش داده می شود.
مجموعه ای از داده های واقعی شرکت تولید کننده انواع سالنامه در تهران به نام شرکت " سالنامه نیک" جهت
اعتبار سنجی و نشان دادن کارایی مدل، مورد استفاده قرار می گیرند. نتایج محاسباتی، به خوبی نشان می دهند که
مدل این مقاله می تواند برای مسائل واقعی برنامه ریزی تولید ادغامی کارخانه های تولیدی مشابه در شرایط عدم
قطعیت پارامترها، کاربرد مناسبی داشته باشد.

چکیده [English]
In this paper, multi-site aggregate production planning for the production of perishable products such as gifts of New Year, calendars and maturities by postponement policy in uncertainty conditions is determined. The production process for these products is proposed to be divided into two phases including the production of final and semi-finished products with applying the concept of postponement. So, there are three production activities, including direct production, the production of semi-finished products and final assembly. Also, a robust optimization model to solve aggregate production planning problem for these products is developed. Finally, a set of real data from a calendar producing company in Tehran called “NIK Calendar” are used to validate and show the efficiency of the proposed model. Results show that the proposed model of this paper can use for similar factories which are active in the field of aggregate production planning with considering uncertainty in the parameters
