Optimum Layout Model of Lift Car for Improving Productivity in High-rise Building Exterior Finishing Work

마감공사 생산성 향상을 위한 리프트 카 최적배치 모델

An operation planning of lift car is crucial in tall building construction especially it's arrangement plans, because it is related with transportation distance of finishing materials affecting construction productivity. Since tall building construction, composed of complicating and huge plane have complex traffic lines of finishing materials, to determine the position of lift car empirically or intuitively has limits. Therefore this paper suggest an optimum layout model of lift car minimizing the transportation distance both at site-level and floor-level using Graph theory and Dijkstra algorithm.
