Study on Application of Statistical Treatment to Estimation of Fundamental Quantity at Initial Design Stage

Abstract

Estimation of fundamental quantity such as hull steel weight, pipe weight, painted area, etc. is very important for the ship's design, especially, at initial design stage. Estimation, however, by detail calculation is so difficult at initial design stage when design has not been developped in detail yet that actual results, technical experiences, etc. are necessary to it supplementary. As statistical treatment seems to be applicable effectively to such estimation, the possibility of the method has been investigated. As the results, it was found that the method using analysis is so useful for selecting variables and making the estimation simple, that it can be put to practical use.
