Consider a multi-channel supply chain (hereafter SC) system, producing and distributing two substitutable products. Within this framework, we study the SC efficiency by comparing several decentralized SC configurations with a centralized one. Our result show that it is often possible to achieve 93.5% or more of the total profit of a centralized SC in a decentralized configuration, which suggest...

Abstract: Bi-level programming, a tool for modeling decentralized decisions, consists of the objective(s) of the leader at its first level and that is of the follower at the second level. Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels. Supply chain planning problem...

Due to the global expansion of Company A's supply chain network, it is becoming more vulnerable to many disruptions. These disruptions often incur additional costs; and require time to respond to and recover from these disruptions. The base paper supply chain was identified as the most vulnerable area of the Company A Jurong and South & Southeast Asia Cluster supply chain; and a multi-stage sup...

Bullwhip effect has always been considered as one of the critical problems in a supply chain that negatively influences costs, inventory, reliability and other important business processes especially in upstream agents. This problem has become even more critical due to the increased complexity of global supply chains. This paper aims to develop a simulation approach based on system dynamics mod...

nowadays, in turbulent and violate global markets an agile supply chain (asc) network is frequently considered as a dominant competitive advantage for survival. to achieve the competitive advantage, companies must align with suppliers and customers to streamline operations, as well as agility beyond individual companies. there are many definitions and models about agile supply chain and most of...

regarding to the diversified needs of domestic and global customers and various products of domestic and global competitors, importance of agility in supply chain management becomes more important. suppliers have to provide materials and essential resources of manufacturers in a short time without any lead time.in this research, we identified many criteria for agility in sanitation supply chain...

According to the Council of Supply Chain Management Professionals (September 2007), we have the following description for supply chain management: “supply chain management encompasses the planning and management of all activities involved in sourcing and procurement, conversion, and all logistics management activities. Importantly, it also includes coordination and collaboration with channel pa...

This paper proposes a strategic multi layers model based on multi agents approach for supply chain system. It introduces a formulation and a solution methodology for the problem of supply chain design and modeling. In this paper we describe and analyze relationships among main entities of a supply chain such as suppliers, producers, and distribution centers in the aim to define their behavior. ...

Three level programming results when second level is itself a bi-level programming. By extending this idea it is possible to define multi-level programs with any number of levels.

The successful implementation of supply chain management depends on many soft issues (strategic/behavioural) such as organizational resistance to change, inter-functional conflicts, joint production planning, profit sharing, team oriented performance measures, channel power shift, information sharing, real time communication, inventory and technical compatibility (Min & Zhou 2002). Many of the ...
