摘要
目的确定航天操作复杂度评价模型中4项评价指标的权重系数。方法采用了2种权重分配法:客观权重法和主观权重法。其中主观权重法采用的是Delphi法+模糊层次分析法+多专家集值统计的方法,通过10名航天员问卷调查得到;客观权重法采用的是SPSS15统计软件的nonlinear的分析方法,对模型验证实验数据结果进行分析得到。结果得到评价指标的2套权重系数。结论主观权重因集合了多位专家的意见,而能适用于不同操作情境;客观权重则较适用于操作情境相同的情况。
Objective To get the weights of 4 evaluating indices in the operation complexity (OC) model of spaceflight. Methods Two weight assignment methods, subjective and objective methods, were adopted. The subjective method was combined with Delphi method, fuzzy analytic hierarchy process (FAHP), and multi-expert set-valued statistics. To get the subjective weights, two trials of survey were carried out among 10 candidate astronauts. The objective method was nonlinear analysis method in SPSS15. The data of the validation experiment for the OC model was analyzed and the objective weights were obtained. Results Two sets of weights were gained. Conclusion The subjective weights are based on the views of multi-experts and can be applied to different operation situations. The objective weights are suitable to be applied in the same operation situation.
