Abstract:
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.
