시뮬레이션을 활용한 강재적치장 운영 효율화 방안에 관한 연구

Abstract

In shipbuilding industry, The steel plate is a representative material constituting the structural part of the hull such as outer panel, inner panel and reinforcing material, which corresponds to about 10% to 12% of the ship price. These steel plate that are produced in steelworks is come in the shipyard and sent to steel stock yard. Therefore, in order to prevent the delay of the process and to observe the delivery date, a management system is required to allow the stocked steel to be input to the pre-treatment process in a timely manner. However, the steel plate used in the shipyard varies in size and material, and the contracts are concluded for several steelworks, so that the variability of the day of arrival is large. Therefore, time and cost are wasted due to the relocation of the steel during the process of moving the steel plate during the stacking and dispensing operations. In order to solve these problems, this study constructed dispatching model by using discrete event simulation(DES). Through this, it is aimed to explore the best way to operate the steel stock yard efficiently while minimizing the movement fo the crane while maintaining the quality of the steel plates.
