Capacity coordination, as the tactical level of hierarchical production planning in hybrid MTS/MTO systems, includes numerous important decisions. In this paper, two of these decisions i.e. finding the best strategy for the acceptance/rejection of incoming orders and determining orders’ due dates – are investigated. Also a simulation model is proposed to evaluate the efficiency of the presented mixed integer model. Finally, an industrial case study is considered in a food processing plant to evaluate the proposed framework and conduct suitable sensitivity analysis.

Abstract [Persian]

توازن ظرفیت ، به عنوان سطح میانی برنامه ریزی تولید سلسله مراتبی در سیستم های تولید ترکیبی MTS/MTO، تصمیمات مهم متعددی را شامل می شود. در این مقاله، دو مورد از این تصمیمات شامل یافتن بهترین استراتژی برای رد یا قبول سفارشات ورودی و تعیین موعد تحویل سفارشات، مورد بررسی قرار می گیرد. همچنین یک مدل شبیه سازی با هدف ارزیابی کارایی مدل عدد صحیح مختلط ارائه شده، تبیین می گردد. در نهایت، یک مطالعه موردی صنعتی در یک کارخانه فرآوری مواد غذایی مورد بررسی قرار می گیرد تا چارچوب ارائه شده مورد ارزیابی قرار گرفته و تحلیل حساسیت های مورد نیاز انجام گیرد.
