چکیده

در مطالعات قبلی، طراحی مدل‌های مدیریت موجودی توسط تأمین‌کنندگان (VMI) بر اساس حداقل هزینه کل زنجیره تأمین بود. در این مقاله، یک روش جدید برای طراحی مدل‌های VMI با هدف بهینه‌سازی گردش موجودی انبار تولیدکننده ایجاد شده است. بر اساس مدل پیشنهادی، هدف ما افزایش حداکثر گردش موجودی همراه با محدودیتِ نداشتن کمبود کالا در خطوط تولید و انطباق با حداقل و حداکثر محدودیت‌های موجودی در انبار تولیدکننده است. روش پیشنهادی در مقایسه با روش های متعارف به حداقل رساندن کل هزینه زنجیره تأمین ساده‌تر و عملی‌تر است. الگوریتم ترکیبی مبتنی بر الگوریتم ژنتیک (GA) با استفاده از بهینه‌سازی ازدحام ذرات (PSO) برای به دست آوردن هر دو توانایی جستجوی مناسب فراگیر و محلی در فضای جواب، برای حل مدل جدید پیشنهاد شده است. به‌عنوان یک مطالعه موردی، اجرای مدل پیشنهادی در زنجیره تأمین شرکت سایپا بهبود در گردش موجودی کالا، کاهش سطح موجودی انبار و کاهش سطح بازپرسازی کالا توسط تأمین‌کنندگان را نشان می‌دهد.

چکیده [English]

In previous studies, the design of the vendor managed inventory (VMI) models was based on minimizing the total cost of the supply chain. In this paper, a new approach for designing VMI models with the aim of optimizing the inventory turnover of the producer warehouse is developed. Based on the proposed model, our objectives are to maximize inventory turnover along with the constraint of lack of shortage of goods in the production lines and also compliance with the minimum and maximum constraints of inventory in the warehouse of the producer which can be simpler and more practical than minimizing the total cost of the supply chain. A hybrid algorithm based on a genetic algorithm (GA) using particle swarm optimization (PSO) is proposed in order to gain both proper global and local search abilities in the solution space for solving the new model. As a case study, implementation of the proposed model in the supply chain of Saipa Company improved the inventory turnover, decreased inventory level and decreased the level of replenishment by suppliers.
