چکیده | ||
The lot sizing and scheduling problems for quick response to the diverse customers’ demands through the optimal utilization of resources and reducing the costs has a particular importance. In this paper, it is investigated the lot sizing and scheduling problem for complementary products. Each package consists of several complementary products with certain portions and different processing times, producing on the parallel production lines in a make-to-stock environment. To solve the problem, it is proposed a hierarchical approach with the objectives of minimizing the package costs, bound and stock, and maximizing the capacity utilization at the first level, and the aim of minimizing the completion time of complementary products at the second level. The second level model is difficult-to-solve in the large-sized instances; therefore, a rolling horizon heuristic solution algorithm is developed whose comparing performance to the exact solution as well as a proposed lower bound in different numerical examples, show the solution quality and its appropriate computation time. To validate the model, the actual data of a tile factory have been employed. Results show that the production plan, costs and times to complete the packages are improved, compared to the current process in the factory. | ||

چکیده [English] | ||
مسئلة تعیین اندازة انباشته و زمانبندی تولید، با استفادة بهینه از منابع و کاهش هزینهها در پاسخ به تقاضای متنوع مشتریان در کمترین زمان ممکن، از اهمیت خاصی برخوردار است. در این مقاله، مسئلة تعیین اندازة انباشته و زمانبندی تولید برای بستههای محصولات مکمل بررسی میشود. هر بسته شامل چند نوع محصول مکمل با تعداد مشخص و زمانهای پردازش متفاوت است که روی خطوط موازی مختلف، در یک محیط تولید برای انبارش تولید میشوند. برای حل این مسئله، یک رویکرد سلسلهمراتبی با اهداف کمینة هزینههای تولید، کمبود و موجودی بستهها و بیشینة استفاده از ظرفیت، در سطح اول و هدف کمینة زمان تولید بستهها در سطح دوم پیشنهاد میشود. حل مدل سطح دوم در ابعاد بزرگ دشوار است؛ بنابراین، یک الگوریتم ابتکاری افق غلتان ارائه میشود که مقایسة عملکرد آن با حل دقیق و نیز کران پایین پیشنهادی در نمونههای عددی مختلف، نشاندهندة کیفیت و زمان حل مطلوب آن است. برای اعتبارسنجی مدل، از دادههای واقعی یک کارخانة کاشی استفاده شده است. مطابق نتایج، برنامة تولید، هزینهها و زمان تکمیل بستهها در مقایسه با وضع فعلی بهبود مییابد. | ||
