The competition between companies for prior occupation of the market is becoming fierce. In this highly competitive situation, it is important for companies to differentiate themselves if they are going to have a chance at success. And the competition to create the best solution method possible is higher than ever. Increased competition is forcing companies to lower costs and improve efficiency. A supply chain management(SCM) has become one of the most important solution methods of competitive advantage. This study has developed a simulator for the supply chain network problem. The simulator is designed to simulate the conditions of an actual supply chain network considering uncertainties. The simulator developed using commercial simulation tool ARENA and the results of computational experiments for a simple example were given and discussed to validate the developed simulator. Further research is needed, but using the simulator could become a useful tool for decision making in the supply chain network area.

To satisfy and respond quickly to customers' demand, many companies are now aggressively focusing on supply chain management in order to strengthen their competitiveness. The modeling and analysis of supply chain environment have been widely studied. This study is concerned with the development of supply chain simulator which deals with stochastic natures existing in the supply chain environment. We proposed the mathematical model for the efficient cost analysis and developed the supply chain simulator based on the proposed mathematical model with object-oriented language C++. The simple experiment which find the best combination of policies considering the whole cost shows the possibility and reasonability of the developed simulator.

The past researches focused on the supply chain network that consists of factories, distribution centers and retailers for single product type. This research is required because the factory for single product type is advanced to reconfigurable type in order to produce various products, according to customers' various purchase forms and time. This research is also required because in the past researches, the material flows from factories to distribution centers and from distribution centers to retailers, but recently, there are material flows between distribution centers. The supply chain network in this research consists of reconfigurable manufacturing system, multi-layered distribution centers, and retailers. A simulator is developed to analyze the material flow on the supply chain network. The developed simulator is web-based designed by using Java Server Page and MS-SQL, so as to maximize the convenience for users.

공급망 관리(SCM: Supply Chain Management)는 공급자, 생산자, 고객에 이르는 공급망(Supply Chain) 전체에 대한 합리화된 통합적 관리를 의미한다. 현재까지 최적화와 관련된 분야들에 대한 연구가 많이 진행되어 왔으나 이러한 최적화 값들의 실제 적용에 관한 연구는 미흡하였다. 이에 본 연구에서는 공급망을 모델링하여 원하는 기간 동안의 시뮬레이션을 통해 공급망을 정량화된 데이터로 표현해 주고, 각 구성 요소에서의 운영정책 변화나 공급망 디자인의 변화와 같은 여러 가지 발생 가능한 변인들이 공급망에 어떠한 영향을 미치는지를 나타내 줄 수 있는 Supply Chain Simulator(SCS)에 대한 개략적인 내용을 살펴보고 개발된 SCS들에 대하여 간략하게 알아보고자 한다.

Many manufacturing industries need more efficient organization since the customer expects a greater response to orders Due to this increased expectation, a supply chain management (SCM) has become one of the most important methods of competitive advantage in business today. This study has developed a simulator for the supply chain management problem. The simulator designed to help determine considering to the capacities and the costs of production and distribution facilities. The simulator developed using commercial simulation tool ARENA and the results of computational experiments for a simple example were given and discussed to validate the developed simulator. The simulator can be used to decide an realistic production-distribution planning in the area.

공급 체인 관리(SCM: Supply Chain Management)는 부품, 기자재, 원료 등의 구매 및 조달 뿐 아니라 제품의 생산 및 완제품의 보관, 운송, 유통, 판매에 이르는 공급 체인(Supply Chain) 전체에 대한 합리화된 통합적 관리를 의미한다. 지금까지 이와 관련하여 수요 예측, 안전재고결정, 최적 수배송 경로 결정 등과 같은 최적화와 관련된 이슈들에 대한 연구가 많이 진행 되어왔으나 이러한 최적화 값들을 실제로 공급 체인에 적용시켜 운영하였을 때 공급 체인망이 어떤 모습을 나타낼 지에 대한 연구는 미흡하였다. 이에 본 연구에서는 공급체인을 모델링하여 원하는 기간동안의 시뮬레이션을 통해 공급 체인망을 정량화된 데이터로 표현해 주고, 각 체인에서의 운영정책 변화나 공급체인 네트워크 디자인의 변화와 같은 여러가지 발생 가능한 변인들이 공급체인에 어떠한 영향을 미치는지를 나타내 줄 수 있는 Supply Chain Simulator(SCS)에 대한 개략적인 내용을 살펴보고 개발된 여러 SCS에 대하여 간략하게 알아보고자 한다.

현대 기업 경영환경의 가장 큰 변화는 개개의 기업들이 기업전체의 효율성과 이익의 향상을 위해서 공급망 (Supply Chain)에 대하여 많은 관심을 기울이기 시작했다는 것이다. 여기서 공급망이란 원료의 조달부터, 중간재로의 가공 및 유통, 최종제품의 생산 및 배송까지의 기능을 수행하기 위한 설비와 유통 채널의 네트워크를 말하며, 모든 기업들은 원자재에서 최종소비자의 형태로 공급망에 참여한다, 결국 공급망의 형태는 산업과 기업에 따라서 매우 복잡하고 다양할 수밖에 없는데, 원재료의 수급에서 고객에게 제품을 전달하는 자원과 정보등 일련의 흐름전체를 경쟁력 있는 업무의 흐름으로 관리하려는 관리 시스템이 공급망 관리(SCM :Supply Chain Management )인 것이다. 기업들의 공급망 관리에 대한 관심이 증대하는 반면에 고객 수요패턴의 불확실성이나 급변하는 기업환경 등 여러 외부 입력 값들의 변화에 따라 효율적인 공급망 구성을 위한 연구는 부족한 실정이다. 이러한 문제를 해결하기 위해 최근 시뮬레이션을 적용한 공급망 시뮬레이터(SCS : Supply Chain Simulator )에 많은 관심이 집중되고 있다. 본 연구에서는 SCS 의 일종인 Arena Professional Edition과 공급망 관리의 성과를 측정하고 개선분야를 직접적으로 파악할 수 있는 SCOR (Supply Chain Operations Reference Model)을 이용하여 제조기업의 효율적인 SCM 의사결정에 대해서 알아보고자 한다.

Due to the fast growing rate of the global container trade, every major port is under the pressure of meeting the projected capacity demand. As a result, alternative solutions have been sought for improving capacity and meeting the growing demand for container storage area and terminal capacity. Moreover, material handling process re-engineering is now a critical issue for logistics and supply chain managers of airline, shipping lines, terminal and warehousing enterprises around the world. Therefore, the purpose of this paper is to develop the 3D simulator for executing performance valuation of port transportation systems. The developed 3D simulator system is to measure the effectiveness of the proposed total system and compare it with existing practices. The performance analysis variables are also defined for these comparisons

There have been research and developments for effective and efficient logistics and progress management in a construction project. Among them, RFID+4D has been developed for the supply chain management of long-lead item materials such as steel component, precast concrete component and curtain wall by integrating RFID with 4D CAD. And the feasibility of RFID+4D has been verified and validated and the benefits in terms of time and cost were shown in several case studies. However, the previous development of RFID+4D has not been adapted widely because of additional modeling cost, non-real time data update, additional labor for data update, and so forth. Therefore, this research has proposed a framework and process for solving these problems. And the web based simulation system has been developed and verified based on the proposed framework. The proposed framework and process can improve the existing RFID+4D system in a construction project by saving its operation cost and utilizing project information more efficiently and effectively. Also it is expected that the proposed framework could be applied to a method transferring design RIM data to construction BIM data.
