The intense competition in manufacturing and the need to introduce new products faster have forced manufacturers to explore unconventional methods of meeting these challenges. In that endeavor, postponement as a new manufacturing strategy has evolved. The research reported in this paper is based on the postponement strategy. A multi-echelon supply chain consisting of a retailer, a warehouse and...

high congestion of returned product at remanufacturing facility causes substantial delays and consequently remarketing value losses for time-sensitive and high-tech products with short life cycles, such as electronic equipments. at the remanufacturing site the returned product are inspected and classified according to their quality and processing time in one of the two classes: class 1 being ad...

The Multi-Echelon Distribution Supply Chain (MEDSC) is a multifaceted structure, focusing on the integration of all factors that involved in the overall distribution process of finished products to the customers. The growing interest in multi-echelon distribution systems has highlighted the need to adopt an appropriate approach to ensure the efficient management of their complexity. While there...

– All-unit order frequency discount • 94%-effective policy for a variable base period – Incremental order frequency discount • 94%-effective policy for a fixed base period • 98%-effective policy for a variable base period Introduction • A supply chain is a network of facilities that procure raw materials, transform them into intermediate goods and then final products, and deliver the products t...

in recent years, there has been a great concern about strategic supply chain management. the supply chain configuration approach is related to strategic management of material and information flows. most of suggested configurations in the part of strategic direction are based on environmental factors and structure-conduct-performance approach. exploring supply chain configuration with emphasis ...

In this paper, a multi-objective multi-period multi-product supply chain network design problem is introduced. This problem is modeled using a multi-objective mixed integer mathematical programming. The objectives are maximizing the total profit of logistics, maximizing service level, and minimizing inconsistency of operations. Several sets of constraints are considered to handle the real situa...

⎯We consider a two-echelon supply chain with two retailers and one supplier. The retailers are supplied by the supplier who makes all the decisions and bears all the inventory risk. Throughout this paper, we consider two different inventory systems: a reserved inventory system and a pooled inventory system. With the reserved inventory system, the supplier keeps separate inventories for each ret...

We present a novel simulation platform called Optimization, Simulation, and Forecasting (OSF) for the domain of manufacturing and logistics supply-chain systems. It supports composition of DEVS, Linear Program (LP), and forecast models using an extended Knowledge Interchange Broker (KIB). Models developed in DEVS-Suite simulator, OPL-Studio optimization, and a heuristic Inventory Strategy Forec...
