조선 전용 GIS와 안벽 시뮬레이터를 이용한 후행 중일정 최적화

Abstract

This paper has focused on the middle term process planning around quays based on the prefixed long-term plan of the product mixedships. Recently, the order rate of high add-value ships in domestic shipyards has been sharply increased and the spending time atquays is accordingly on an increasing trend. For proper and practical process planning related to quays, it has to be closely connectedwith a long-term plan and product calendar, erection network and result of ship allocation around quays. Moreover, it is also requiredto include the integrated consideration of the whole process of a yard, each ship, and each team respectively. The most distinguishingfeature of this study is that it would run on the ship allocation simulator and GIS framework in order not to be limited to the specific oneyard and the readers can figure out the optimization formulation containing the work load leveling and a different approach fromPERT/CPM. The proposed approach reflected all requirements from the department of process planning and management in a shipyard,and the analysis of the results has explained its performance of the optimization result with the examples of total 43 ships underconstruction from 2008 to 2013.
