Research On Evaluation Method Of System-of-Systems Capability Level Based On Capability Combination

The confrontation between the system-of-systems(SoS)has become the basic feature of the future war.The victory and defeat of the SoS confrontation is more and more dependent on the support and play of the SoS’s capability.The intergral level of the SoS’s capability under modern conditions is related to the initiative of the battlefield and even the outcome of the war.The level of the SoS capability of an army must be compatible with the form of war in its era,in line with the needs of the country’s expansion,and in line with the level of military modernization.At present,in the process of capability building of our military SoS,there are problems such as unclear capability relationship,lack of horizontal interaction,and lack of integration of capabilities.In view of the above problems,this paper focuses on improving the level of SoS capability building,mainly to assess the level of SoS capability in the context of military application,to evaluate SoS capabilities from activities and effects,to consider the impact dependence between capabilities,and to build a task-oriented capability combination model.A method for assessing the intergral level of SoS capability is proposed.First,analyze and evaluate SoS activities.A framework for assessing the level of SoS capability based on activity effectiveness is proposed.Differentiate whether or not to consider the impact of the combination of capabilities.Analyze the relationship between capabilities and activities,determine operational activities,analyze relationships between activities,and build an activity network model.Based on the activity loop,an evaluation index such as loop betweenness and activeness is proposed to judge the activity weight on the loop.Taking the weight of the activity in the loop as a reference,the distance decay function is used to evaluate the activity weights that are not in the loop.Secondly,a comprehensive level assessment method for SoS capability that does not consider the impact of capability combinations is proposed.This paper analyzes the relationship between capabilities,and proposes an analysis method of capability influence dependency based on the activity network.Consider the actual effect of the activity in the combat process,evaluate the activity attribute of the activity according to the activity effect index,determine the activity effect by using the effect attribute,and evaluate the underlying capability level of the system based on the activity effect.According to the capability hierarchy,from the bottom up,the comprehensive level of the SoS capability is assessed based on the capability index weights.Thirdly,a method for assessing the intergral level of SoS capability based on capability combination is proposed.An overview of the capability combination,clarifying the meaning and definition of capability combination,based on the activity loop and the correspondence between capabilities and activities to find a capability combination that can accomplish a particular task.Combine the relevant knowledge of the decision-making process,establish a capability combination evaluation model,and propose a corresponding evaluation solution.Based on the capability combination,the statistical mean method and the distribution comprehensive method are used to assess the intergral level of SoS capability.Finally,through the analysis of an area air defense combat system to verify the correctness and effectiveness of the assessment method proposed by the paper.The tasks,activities,and capabilities of the area air defense combat system are described in a formal manner according to the methods proposed by the paper,and from the activity effect indexes,activity effects,activities,underlying capabilities,sub-capabilities and capability combinations,step by step,the final calculation of the comprehensive level and intergral level of SoS capabilities.According to the evaluation results,the targeted improvement measures for the capability building of the area air defense combat system are proposed to provide a basis for improving the capability level of the SoS.
