چکیده

جهانی شدن و ظهور رقابت پذیری و اثر آنها بر خط مشی سازمان­ها به برون سپاری قطعات و خدمات باعث شده است که شرکت­ها به عملکرد خرید و تصمیم گیری­های مرتبط با آن، همچون تصمیم به خرید و زمانبندی خرید اهمیت قابل توجهی دهند. لجستیک به موقع و به ویژه خرید به موقع آنجا اهمیت مضاعف می­یابد که در برخی صنایع مانند نساجی و پوشاک، وجود موجودی و نگهداری آن و پیروی از سیستم‌های تامین و تولید سنتی، منجر به عملکردی نا­مناسب در بازار می‌شود. لذا در این مقاله، مدلی مفهومی بر کاربرد مفهوم به موقع در بخش خرید یک زنجیره عرضه پوشاک ارائه می­شود. در این راستا، مقوله­ای مانند شناسایی و طبقه­بندی چند معیاره اقلام و تامین‌کنندگان تحت شبکه به موقع در نظر گرفته شده و بر پایه هزینه­های لجستیک، مدل تثبیت شده حمل با بررسی انواع وسایل نقلیه، جهت جمع‌آوریاقلام از تامین کنندگان پیشنهاد می­شود. ضمن پیاده سازی الگوریتمی برای رویه حمل یکپارچه، میزان تاثیرپذیری هزینه‌ها با استفاده از مطالعه عددی در زنجیره عرضه کالای نساجی (کت و شلوار) تحت بررسی قرار می­گیرد.

چکیده [English]

Globalization and competitiveness and their effort on outsourcing approach of an organization have involved it to consider purchasing role and its performance in supply chains as an important issue. Regarding JIT purchasing advantages in manufacturing industries, there is a growing trend toward JIT purchasing in research studies. Due to inventory and its related costs especially in textile and clothing industries, traditional procurement and production systems lead to unprofitability. Therefore, JIT logistics and purchasing have an important role in these industries. In this paper, we propose a conceptual model for JIT purchasing in a clothing supply chain. Via generalizing items and supplier classification strategies under Just-In-Time network, a freight consolidation model for gathering items based upon logistics costs is developed. An efficient algorithm for freight consolidation policy in the clothing supply chain is implemented. Finally, an illustrative example is used to show the model applicability and logistics cost efficiency of approach.
