This paper deals with the application of Supply Chain Operations Reference (SCOR) model to make a Service Supply Chain(sSC) of a hospital treatment service. At first, we compare the service supply chain with the traditional supply chain. At second, we app

  The most of national industrial complex were developed and supplied not according to the requirements of enterprise but the needs of the government. And it leads to current serious out of balance in demand and supply of industrial complex. Buckpyoung in

  본 연구에서는 철강 제조 공정에서 발생하는 생산 계획 문제를 설명하고 해결 방법을 제시한다. 철강 제품 중에서도 판재류(냉연, 아연도, 석도, 칼라 제품)를 생산하는 공정으로 연구 범위를 제한하고 적용하는 부분은 철강 공정의 스케줄링 분야를 배제한 생산 계획 분야만을 대상으로 한다. 특히, 철강 제조 공정의 생산 계획 문제들 중에서 가장 중요하게 고려되는 원료 충당 문제, 용량 할당 문제, Batched Annealing Furnace(BAF) 설비

In steady-state simulation the output data of the transient phase often cause a bias in the estimation of the steady-state results. A common method is to cut off this transient phase. This paper presents a new heuristic used to detect the warm-up period in steady-state simulation output. An evaluation procedure is used to compare the presented rule, called EVR, with the method MSER-m known as the most sensitive rule in detecting bias and most consistent rule in mitigating its effects. The rules are applied to the output generated by M/M/1 queuing process and the performance of the methods is tested at 4 different levels of utilizations. Various measures of goodness are used to assess the effectiveness, consistency and confidence of the methods.

In this paper, we optimize simulation model of a manufacturing system using the real-coded genetic algorithm. Because the manufacturing system expressed by simulation model has stochastic process, the objective functions such as the throughput of a manufa

In this paper, we propose a case study to treat planning and scheduling in factory of supply chain. In fact, the planning and the scheduling of a factory are not easily solved because of constraints of facility resources, material requirements, allowed planning times, and so on. However many packages are developed by vendors in Advanced Planning and Scheduling(APS) aspects to solve these problems. We, therefore, analyze problems of an electronic company and apply the tool, Factory Planner(FP), to solve problems.
