This paper indicated an inactive preference-weight method for Genetic Algorithm (GA), which can turn the individual's preference into weight preference in the multi criterion satisfactory optimization. DM can use the preference-weight to rebuild the fitness function, and according to binary relations of sample points based on the information of DM's preference, inactively modifies the evolution direction...
In the practice of evaluation of optimum FRP trawler type, DM has to face multi disciplines and lots of uncertain or fuzzy parameters. This paper proposes the use of symmetrical fuzzy collaborative optimization model, and the traditional ship type evaluation model is decomposed into three subsystems, i.e., technological, economy and decision-making computation discipline. The fuzzy cut level optimized...
