面向相互比较的装备体系建设贡献率评估

为有效解决当前装备体系贡献率评估结果难以相互比较的难题，从装备体系建设与设计视角，选取装备额定条件下完成体系规定任务率作为装备体系贡献率的度量指标，将装备体系贡献率评估转化为装备体系设计中的装备完成体系规定任务率优化分配。运用求解优化模型的拉格朗日乘数法，得出所求条件极值的可能极值点，并作为装备体系内装备完成体系规定任务率的优化分配结果。针对装备体系内装备之间并联、串联和混联3种类型的关联协作关系，应用概率论和拉格朗日乘数法，分别构建和求解这3种类型的装备体系完成任务率函数和建设贡献率评估模型，实现了装备体系建设贡献率的统一度量和对比分析。算例结果验证了评估模型的有效性和可行性。

Intercomparison-oriented Evaluation of Equipment's Contribution Rate to Armament System-of-Systems Construction

The evaluated results of equipment's contribution rate to armament system-of-systems construction（ECRASSC）are difficultly compared. In the armament system-of-systems construction and design，the completion rate of assigned tasks under the rated conditions of equipment is taken as the metrics for ECRASSC，and the evaluation of ECRASSC is translated into the optimal distribution of task completion rate in armament system-of-systems design. Lagrange multiplier method is used to solve the optimal model，the possible extreme point of the condition is obtained as the optimized result of completion rate of assigned tasks. In the light of the three type cooperative relationships of serial，parallel and hybrid configurations between armaments， the three type functions of task completion rate is established by using the probability theory and Lagrange multiplier method，and the three type ECRASSC evauation models are solved，realizing the unified metric and comparative analysis of ECRASSC between all armaments. The validity and feasibility of evaluation model is verified by a case study.
