An index system for selecting an optimal construction project is established. Due to the uncertainty and the inaccuracy of information during the evaluation process, an evaluation selection model based on fuzzy analytic network process method is proposed. The weight of each index, including the weight of the criterion level indicators, the weight of independent sub-indices and the weight of dependent...
In this paper, we selected a kind of trimaran model to study its rapidity by theoretical research, ship model test and numerical simulation. Based on the rapidity test and ISIGHT-FD software platform, we set up mathematical model, selected the genetic algorithm method as system identification method. According to ship resistance and ship propelling, we analyzed the effect to its rapidity performance,...
