Model for Multi-objects and Multi-layers System for Ship Form Fuzzy Optimization

The optimal selection of ship forms is a multi-objects and multi-layers fuzzy evaluation problem, therefore there are many factors which should be taken into account. In this paper, the objects are separated into interrelated parts to make the problem consecutive, then using the Fuzzy Pattern Recognition model and Fuzzy Optimization theory brought forward by references[1] and [2], every layer cell system is calculated by inputting the output of the lower into the higher. Lastly, by means of the eigenvalues of different calsses vectors, sequence of all the schemes is arranged and optimal selection for ship forms is performed. The example given in this paper shows that the model is reasonable with the credible results and high discrete judged values. It provides a reference for choosing a ship form reasonably.
