서비스 공급사슬의 시뮬레이션에 관한 연구

Abstract

시뮬레이션 모델링은 공급사슬에서 시스템의 설계와 분석을 위해 사용되는 방법론이다. 본 연구는 서비스 공급사슬의 시뮬레이션을 위한 개념적 모델의 설계를 목적으로 한다. 기존 공급사슬 시뮬레이션은 제조 공급사슬을 중심으로 연구되어, 서비스를 중심으로 다루는 공급사슬에 적용하기 어렵다. 이는 서비스 공급사슬의 개념적 모델에 대한 연구가 미흡하여, 시뮬레이션 모델 설계를 어렵기 만든다. 서비스 공급사슬의 시뮬레이션 설계에는 서비스가 갖는 다양한 형태와 가변성을 고려해야 한다. 따라서 본 연구에서는 서비스 공급사슬 시뮬레이션의 일반적인 모델을 도출하기 위한 객체지향 기법에 기초한 시뮬레이션의 개념적 모델 설계에 관한 절차를 제안한다. 객체지향 관점의 모델링은 복잡한 시뮬레이션 모델 설계에 있어서 매우 효과적이며, 방법과 구현단계를 잘 설명한다. 또한 설계된 개념적 모델을 이용하여 실제 모델 코딩에 ARENA?? 시뮬레이션 패키지 환경에서의 모델 설계 절차를 제안한다. 본 연구는 서비스 공급사슬 시뮬레이션을 다루는 최초의 연구로써 앞으로 연구될 서비스 공급사슬의 기초가 될 수 있으며, 제시된 시뮬레이션 모델과 구현 절차는 다른 연구자나 실무자가 참고하거나 재사용함으로써 서비스 공급사슬 모델링을 하는데 지침이 될 수 있다.|In recent, it is important to understand service supply chain because the economy moves from manufacturing to services. However, most of existing supply chain research focuses exclusively on the manufacturing sector. To overcome this situation, it needs to investigate and analyze service supply chain. Simulation modeling is one of the mostly utilized methodologies for analysis and design of supply chain management system. Service supply chain has a variety of diverse structures. Consequently, it is harder to design a conceptual simulation model than a manufacture supply chain. In this paper, we develop service supply chain simulation models, based on object-oriented approach. Service supply chain takes advantage of programming an objective-oriented model to build up a conceptual model of simulation because of its diversity and changeability. Objective-oriented modeling has demonstrated an effective simulation design and the practical process. Especially, it is based on the UML analysis/design tools and on the ARENA�� simulation language. The two main features of the proposed procedure are the definition of a systematic conceptual procedure to design service supply chain models and of a set of rules for the conceptual model translation in an ARENA�� simulation language. The goal is to improve the knowledge on service supply chain management with the developed model and support the simulation model development efficiency on service supply chain.; In recent, it is important to understand service supply chain because the economy moves from manufacturing to services.
