요소작업 기반 티어공법 철골조립 시뮬레이션 모델

다국어 초록 (Multilingual Abstract)

This paper presents a simulation model that facilitates to analyze and estimate both time and cost of the steel erection operation making use of tier construction method. By conducting motion and time study, resource processes of the operation and their tasks of the processes are defined. These atomic tasks are used as a building block to implement a simulation model that reflects the real world steel erection operation assembling the steel material in the job site. Task based operation simulation model deals with local variables or delay factors affecting productivity and improves the reusability of existing production models. Therefore, the proposed approach allows the model to adjust more easily to construction method change. The proposed steel erection model was verified by comparing with the Construction Standard Production Unit system (CSPU) and daily work report.
