چکیده

توجه روزافزون به خواسته‌های مشتریان در فرآیند تولید محصولات و همچنین ویژگی‌ها و هزینه‌های اجتناب‌ناپذیر فرآیندهای تولید، پژوهشگران و صنعتگران را به‌سوی مدیریت سفارش‌ها و انتخاب درست سیاست مدیریت موجودی هدایت کرده است. پژوهش پیش رو به‌دنبال یافتن ساختاری برای تعیین مکان بهینه نقطه نفوذ سفارش مشتری و سیاست بهینه مدیریت موجودی، به‌عنوان یکی از مهم‌ترین تصمیم‌های استراتژیک در فرآیند تولید است؛ به این منظور، مدلی مبتنی بر شبیه‌سازی گسسته‌ پیشامد برای محاسبه واقع‌بینانه معیارهای هزینه و زمانِ در جریان ساخت، تحت سناریوهای مختلف طراحی شد. برای اعتبارسنجی و اجرای مدل، اطلاعات تولید و فروش یک کارخانه تولید مواد شیمیایی مورداستفاده قرار گرفت. نتایج حاکی از آن است که استفاده ترکیبی از سیاست‌های مدیریت موجودی، باعث کاهش هزینه‌ها و زمان تحویل سفارش‌ها می‌شود.

چکیده [English]

The increasing attention to customer demands in the product process, and the inevitable features and costs of production processes has led researchers to manage orders and choose the right policy for inventory management. This article identifies the structure for determining the optimal location of the Customer Order Decoupling Point and the optimal inventory management policy as one of the most important strategic decisions in the production process. So, we developed a discrete-event simulation model for realistic calculation of cost and Flow time, under different scenarios, and we used the production and sales information of a chemical plant for validation and implementation of the model. The results suggest that the use of a hybrid inventory management policy reduces the cost and delivery time.
