This paper introduces a capacitated mixed integer programming (CMIP) model for solving an integrated production-distribution system design problem (PDSDP) in the seedling supply chain management (SCM) of a multi-unit Finnish nursery company. The model was originally developed from a strategic perspective in which a company desires to evaluate the expansion or closure of its facilities. Neverthe...

An almost universal assumption in the bullwhip effect modeling literature is that excess goods may be returned without restriction. We seek to determine if returns impact the level of bullwhip effect observed in a multi-stage supply chain. We build a hybrid agent/ discrete-event simulation model of a supply chain and execute it under various conditions of demand variance, lead-time variance, in...

This paper presents an agent-based fuzzy constraintdirected negotiation mechanism for planning and scheduling in supply chain. The supply chain scheduling problem is modeled as a set of fuzzy constraint satisfaction problems (FCSPs), interlinked together by inter-agent constraints. For converging each distinct firm’s interests, the conflicts among the set of FCSPs are resolved through negotiati...

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...

todays, improving the competitiveness of companies and rapidly responding to diverse customers’ demands requires efficient management of the supply chain. integration is one of the effective indices in a supply chain, and vendor managed inventory (vmi) is one of the innovative approaches in this field. in this paper, an integrated model based on a vmi system for deteriorating and ameliorating i...

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...

This work addresses the supply-chain coordination in the virtual enterprise environment, pointing out a system developed in the scope of the ESPRIT Prodnet-II project to provide an advanced functionality to manage distributed business processes at the operational level. A wider system architecture being investigated to provide a smart functionality to manage a dynamic supply chain network is fo...

This paper focuses on the development of simulation-based environment for multi-echelon cyclic planning and optimisation in the product maturity phase. It is based on integration of analytical and simulation techniques. Analytical techniques are used to obtain initial planning decisions under conditions of stochastic demand and lead time, whereas simulation techniques extend these conditions to...
