Decision-makers in shipyards face the problem of determining the design cost concerning the information level contained in drawing and how it influences the shipbuilding process efficiency. Shipyards have their approach and shipbuilding practices about the level of functional technical documentation usage directly in ship production. However, decisions may vary related to the ship type, complexity, size, and deadlines. The shipbuilding decision-making optimization model based on functional technical documentation defines an algorithm for creating and analyzing the data representing the effects of applying functional technical documentation in ship production. Based on such analysis, it is possible to decide the preferred shipbuilding strategy, based on the level of functional technical documentation usage directly in ship production at the level other than one identified in the ship contractual stage, reducing overall shipbuilding costs. By varying different factors of the technological phase of ship production and the relative labor cost with the level of functional technical documentation usage directly in ship production, the curves of the shipbuilding cost and duration deviations, in relation with the value specified by the reference point, are obtained. Also, such analysis provides relevant conclusions about the trend of losses or savings of budget and labor hours based on the level of functional technical documentation usage directly in ship production.
