Abstract: Evaluation of command capability usually adopts combinations of qualitative and quantitative methods. The objectivity of qualitative evaluations directly affects the credibility of evaluation results. In order to evaluate the commander command capability more scientifically and reasonably, we first set up evaluation indices and standards of command capability. Secondly, an expert reliability model based on expert authority degree, objective credibility and certainty degree is established. The index weight correction of evaluation index systems and the determination of the end index are achieved using the model. Evaluation data show that, the method makes results of the comprehensive evaluation further eliminate the influence of subjective factors of experts and improves the objectivity and credibility.
