This paper focuses on fuzzy multiple-attribute decision with weights unknown and fuzzy information. Starting from the structural feature of fuzzy information, we propose the compound quantification description mode based on centralized quantification value, and establish a fuzzy information comparison method based on synthesizing effect. Through real case, all the results indicate that the fuzzy multiple-attribute...
In this paper, in view of the slowness and the locality of convergence for simple particle swarm optimization (PSO) in solving the complex system optimization, a two stage composite particle swarm optimization (TS-CPSO) is proposed as an improved PSO with the strategy of gradual range contraction. The designing ideas and the implementation of TS-CPSO are also given, and the convergence is analyzed...
A real data simulation study of computerized adaptive testing (CAT) of Chinese soldier personality questionnaire (CSPQ) was conducted to find out the feasibility of using count-down method to realize the CAT of personality questionnaire. The data was from 100,125 normal Chinese young people. All participants were male, and the mean age of the individuals was 18.3 (range 16-21, SD = 2.5). The data...
