Product-Centric Simulation for Proactive Evaluation of Production Plan in Shipyard

The shipbuilding industry encompasses various stages in constructing a ship, culminating in the final product. Managing and optimizing these complex processes necessitates considerable time and feasible mid- to long-term planning. A crucial aspect of effective and competitive production management within the shipbuilding industry involves establishing and implementing accurate production plans tailored to the specific situations. While various attempts have been made to utilize modeling and simulation methodologies for this purpose, they have often been hindered by difficulties in accurately capturing the actual situations and constraints of the production site. This paper proposes the use of a product-centric simulation for proactive evaluation of master production plans, alongside the prediction and validation of these plans using shop floor data. By an industrial case study for a Korean shipbuilding company, the effectiveness of the proposed methodology was verified through comparison with existing way. By product-centric simulation, it is expected that production planning could become more accurate by reflecting the actual situation and constraints.
