[ 1 ] - زمان‌بندی در یک مرکز بارانداز براساس زمان ترک مشخص کامیون‌های خروجی
با توجه به گسترش مفاهیم باراندازها به‌صورت تئوری و به‌تبع آن توسعة مراکز بارانداز در سراسر دنیا، بسیاری از شرکت‌ها به بهره‌گیری از این مراکز تمایل یافته‌اند. این مراکز با تجمیع سفارش‌ها و ارسال آن‌ها به‌صورت یک‌جا، توانسته‌اند هزینه‌های حمل‌و‌نقل را تا حد زیادی کاهش دهد. البته نحوة اداره و زمان‌بندی در این مراکز یکی از مشکلات عمده‌ای است که ممکن است اثرگذاری در این مراکز را تا حد زیادی تحت تأث...
[ 2 ] - Integrated production-Inventory model with price-dependent demand, imperfect quality, and investment in quality and inspection
In practice, manufacturing systems are never perfect and may have low quality outputs. Therefore, different decisions such as reprocessing, sale at lower prices or diminishing are made according to industry and market. This paper investigates the importance of supply chain coordination through developing two models in centralized decision-making for an imperfect quality manufacturing system wit...
[ 3 ] - Optimal Manufacturer-Retailer Policies in a Supply Chain with Defective Product and Price Dependent Demand
This study deals with a two-level supply chain consisting of one manufacturer and one retailer. We consider an integrated production inventory system where the manufacturer processes raw materials in order to deliver finished product with imperfect quality to the retailer, where number of defective product has a uniform distribution. The retailer receives product and conducts a 100% inspection....
[ 4 ] - Determining Optimal Number of Suppliers in a Multiple Sourcing Model under Stochastic Lead Times
Employing more than one supplier and splitting orders between them is a strategy employed in supply chains to lessen the lead-time risk in unstable environments. In this paper we present a multiple-sourcing inventory system with stochastic lead-times and constant demand controlled by a continuous review, reorder point-order quantity inventory policy. We consider the situation in which the order...
