Establishing ship newbuilding production costs structure represents a fundamental management activity, concerning materials and fabrication in shipbuilding. Shipyards are competing in world market niches, regarding vessel types and dimensions. Therefore, vessel's market price has a tremendous influence at shipyard's determination of vessel price offered to buyers. For this reason shipyard management is forced to concentrate its effort towards newbuilding production costs structure optimisation as to achieve the goal of profitable shipyard enterprise. In this paper, a computer integrated costs structure optimisation model for defining an optimal and profitable vessel production costs structure is presented. Statistical analysis of data was performed for a sample of tankers population, built in selected shipyards. Probabilistic theory was applied and several results such as of expectation for aggregate figures are presented. Such developed tool for obtaining an optimal production costs structure enables shipyard management more effective decision making, and also, latter through the process, better costs control within model parameters. Furthermore, dynamical control of costing figures for the whole shipbuilding process is possible and has significant influence upon performance final results. Mathematical model for achieving optimal structure of production costs was verified and tested against real example for tanker newbuilding.
