Abstract

In this study, we developed a simulation model for supply chain management of Precast Concrete (PC) based construction. To this end, information on the Factory Production/Site Construction system was collected through literature review and field research, and based on this information, a simulation model was defined by describing the supply chain, entities, resources, and processes. Next, using the Arena simulation software, a simulation model for the PC supply chain was developed by setting model frameworks, data modules, flowchart modules, and animation modules. Finally, verification and validation were performed using five review methodologies such as model check, animation check, extreme value test, average value test, and actual case test to the developed model. As a result, it was found that the model adequately represented the flows and characteristics of the PC supply chain without any logical errors and provided accurate performance evaluation values for the target supply chains. It is expected that the proposed simulation model will faithfully play a role as a performance evaluation platform in the future for developing management techniques in order to optimally operate the PC supply chain.

본 연구에서는 PC (Precast Concrete) 공법 기반 건설공사에 대한 공급사슬 관리를 위한 시뮬레이션 모형을 개발한다. 이를 위해, 문헌과 현장 조사를 통해 공장 제작/현장 시공 체계에 대한 자료를 수집하고, 이를 바탕으로 공급사슬, 개체, 자원, 공정 등을 서술함으로써 시뮬레이션 모형을 정의하였다. 이어서, Arena 시뮬레이션 소프트웨어를 이용하여 데이터 모듈, 플로차트 모듈, 애니메이션 모듈을 작성함으로써 PC 공급사슬 시뮬레이션 모형을 개발하였다. 마지막으로, 개발된 모형의 논리성 검증과 유효성 확인을 위한 모형검토, 애니메이션 검토, 극한치 검증, 평균치 검증, 실제 사례 검증 등의 방법론을 이용하여 모형의 타당성을 검토하였다. 검토 결과, 개발된 시뮬레이션 모형은 논리적 오류 없이 PC 공급사슬의 공정과 특성을 적합하게 표현하고 있었으며, 더불어 대상 공급사슬에 대한 정확한 성능평가 예측치를 제공하는 것으로 나타났다. 향후, 본 연구에서 개발된 시뮬레이션 모형은 PC 공급사슬 체계를 최적 운영하기 위한 관리 기법을 개발함에 있어 성능 평가를 위한 플랫폼으로서의 역할을 충실히 수행할 수 있을 것으로 기대된다.
