Abstract :
[en] This paper will present a way to minimize cost in shipbuilding industry by using the results of a data mining analysis aiming to improve the cost knowledge of the straightening process.
This statistical analysis was based on production data from a shipyard and has the scope to establish an assessment formula of the straightening workload. An intermediate step of the analysis was to estimate the welding distortions appearing in stiffened panels. Those generated formulae are useful to improve the research in the following domains: production simulation, cost assessment of ship hull, structure optimization, design for production, etc.
