Sažetak
Integration of ship design and ship production is necessary for efficient shipbuilding process while it requires very complex documentation planning in particular regarding its level of information and the completion scheduling. Optimally organised documentation planning could largely influence the shipbuilding total cost and lead time. Drawings finished with higher level of unreliability are shortening design phase but could result with major repair and rework activities that could increase production time and cost. On the other hand, insisting on fully completed drawings will increase design stage time and will minimize repair and rework activities, but not necessarily the shipbuilding cost and lead time. This paper researches drawings designing sequence and its unreliability due to designing with unknown, incomplete or unreliable information. Therefore, analysis of documentation planning is performed based on their interdependence, production requirements, production technology level and labour costs. Finally, a new approach for ship’s drawings planning based on drawing’s reliability is proposed with support of developed computer application. Such approach calculates unreliability of interdependent drawings and propose optimal documentation package regarding its level of information and lunching sequence towards production process.
