Abstract

The schedule management in construction project have been performed independently by two method, WBS base management and CBS based management, However, the integrated management model is needed according to efficiency of construction project management and introduction of new EVMS system of KOREA government. For this purpose, interworking database system is designed through efficient modeling of WBS based management data and CBS based management data and relation establishment between entities in this paper. WBS based management DB consists of 4 entities and CBS based management DB consists of 3 entity and one of the 4 WBS DB entities is used to play interworking role between WBS and CBS, Also, attributes of all entities are well defined so that data consistency, integrity and newest are guaranteed. The designed interworking database model was realized using Nex-Pert Pro and the efficiency of data interworking was proved.

본 논문에서는 활동중심의 공정관리와 내역중심의 기성관리로 각각 이원화되어 운영되고 있던 건설공사의 진척관리를 통합 연동하여 관리 할 수 있도록 하기 위한 데이터베이스 모델을 제안한다. 이를 위해 본 논문에서는 활동중심 공정관리 DB를 4개의 엔티티로 구성하고 내역중심의 기성관리 DB를 3개의 엔티티로 구성하여 독립적으로 운영될 수 있도록 함과 동시에 활동중심 공정관리 DB내에 연동 엔티티를 이용하여 내역중심 기성관리 DB내 엔티티와의 관계설정을 통해 두 가지 공정관리 시스템내의 데이터들이 연동될 수 있도록 하였다. 또한, 데이터의 공유를 위해 기본적으로 요구되는 데이터의 일관성, 무결성 및 최신성을 유지할 수 있도록 연동 엔티티 속성을 정의하였다. 제안된 개선된 데이터베이스 모델을 실제 구현하고 활용성 검증을 통하여 데이터의 연동 및 효율성을 입증하였다.
