Lean manufacturing in shipbuilding with Monte Carlo simulation

The shipbuilding industry is very competitive, and shipyard management must strive to improve productivity as a way of keeping up with world competition. Analysis of the assembling of interim products through shipyard process lanes is important from a standpoint of modern shipbuilding techniques and methods which includes the lean manufacturing and design for production concepts. Whereas the design for production concept has bean readily applied in many shipyards, a lean manufacturing methodology for shipyards is lacking. Therefore, the aim of this paper is to provide a methodology for improving the flow of interim products by applying the lean manufacturing concept. Since shipyard management is usually not sure how to approach a transformation of its facilities due to the risks involved, this paper couples lean transformation with Monte Carlo simulation in applying the key parameter for comparing productivity, man-hours. The simulation involves process engineering transformation of an actual shipyard’s panel-block assembly facilities. Application of the lean manufacturing methodology brings productivity improvements of 60%.
