چکیده مقاله :
مدیریت زنجیره تأمین از مباحث جدید در حوزه مدیریت صنعتی می باشند. در محیط کسب وکار در حال تغییر امروز، ارتباط بین بخش های مختلف زنجیره تأمین از اهمیت ویژه ای برخوردار است. یکی از مهمترین این بخش ها، بخش خرید و تأمین مواد می باشد، زیرا قسمت عمده ای از هزینه نهایی تولید یک محصول را هزینه خرید مواد اولیه تشکیل خواهد داد. انتخاب صحیح تأمین کنندگان، ضمن کاهش هزینه های خرید رقابت پذیری شرکت را افزایش می دهد. علاوه بر این یکی از مهم ترین تصمیماتی که می بایست در کنار انتخاب تأمین کننده در نظر گرفته شود، تعیین میزان خرید از هر تأمین کننده است. با توجه به اینکه خودرو از هزاران قطعه تشکیل می شود، این امر در صنعت خودرو از اهمیت بسزایی برخوردار است. در این مقاله ابتدا با بکارگیری تکنیک هایی از تصمیم گیری گروهی چند شاخصه، به شناسایی معیارهای مؤثر در انتخاب تأمین کنندگان شرکت ایساکو پرداخته و سپس تأمین کنندگان اقلام مصرفی این شرکت را اولویت بندی می نماییم. در نهایت نیز با استفاه از یک مدل برنامه ریزی عدد صحیح مختلط، برنامه بهینه خرید را مشخص خواهیم نمود. نتایج این تحقیق که بیانگر برترین تأمین کنندگان اقلام مصرفی و مقدار بهینه خرید است به مدیریت بهتر تأمین کنندگان این اقلام توسط ایساکو کمک خواهد کرد. برای مثال ما نشان می دهیم که یک تأمین کننده در خرید اکثر اقلام مصرفی اولویت دارد و یا تأمین کننده ای دیگر برای هیچ خریدی مناسب نیست.
Supply chain management is a new issue in the field of industrial management. In the current changing business environment, communication between different parts of the supply chain is important. One of the most important parts of a supply chain is material purchasing from different suppliers as a major part of the marginal cost of a product is raw material cost. Selecting suppliers correctly will reduce procurement costs and increase the competitiveness of companies. Moreover, one of the most important decisions that must be considered is the determination of order quantity. As an automobile is comprised of thousands of parts, choosing the right suppliers and determination of orders quantity are very important in the Automotive Industry. In this paper, we first identify the criteria for the selection of suppliers of ISACO Company. Then, suppliers of consumable items are ranked using group decision-making techniques. Finally, we determine optimum purchase plan using a mixed integer programming model. The results of this paper which show the best supplier of consumable items and the optimum purchase quantity can help ISACO to manage suppliers properly. For example, we demonstrate that one supplier has priority for buying the most consumable items or another supplier isn’t suitable for any purchase.
