Review Of Evaluation Methods Of Contribution Rate To System Of Systems, Xiaojing Yin, Xiaofeng Hu, Rong Ming, Haiyang Liu, Yongli Yang Dec 2019

Review Of Evaluation Methods Of Contribution Rate To System Of Systems, Xiaojing Yin, Xiaofeng Hu, Rong Ming, Haiyang Liu, Yongli Yang

Journal of System Simulation

Abstract: The warfare is the encounter of system of systems (SoS). The evaluation on the contribution rate to SoS is of great importance to the development of operational SoS as a measure of the evaluating units’ contribution to SoS. In this paper the basic concept and classification of the contribution rate to operational SoS are elaborated; its connotation and nature are analyzed; and the current research status and the technical difficulties in this research field are summarized. The development trend is predicted, which provides a useful reference for relative research.


Important Object Recognition Method For C4Isr System Based On Operation Traffic Mining, Zhou Fang, Chu Wei, Wendi Cheng Jan 2019

Important Object Recognition Method For C4Isr System Based On Operation Traffic Mining, Zhou Fang, Chu Wei, Wendi Cheng

Journal of System Simulation

Abstract: Considering the problem of vital object recognition for C4ISR system under confrontation condition, a vital object recognition method based on operation traffic mining is proposed. The system operation traffics are collected, the operation data packet describing model is established based on six attribute group described method. The operation traffic association matrix and connectivity matrix are built based on the source IP and destination IP address on data packet. The inflow and outflow operation traffics about system node are counted, and the system vital computation model is established based on statistical traffics as the measurement criteria of system …


Research On Evaluation Framework Of Coa Based On Wargaming, Haiyang Liu, Yubo Tang, Xiaofeng Hu, Guangpeng Qiao Jan 2019

Research On Evaluation Framework Of Coa Based On Wargaming, Haiyang Liu, Yubo Tang, Xiaofeng Hu, Guangpeng Qiao

Journal of System Simulation

Abstract: Aiming at the evaluation problem of COA (course of action) level indicators in joint operation, an evaluation framework of COA based on wargaming was proposed. By multidimensional analysis of wargaming data, an evaluation feature space was constructed from basic features generated by data cube models and SoS (system of systems) features based on complex network. Wargaming experiments were used to generate small batch metrics results of COA level indicators, and the corresponding result labels of evaluation feature space data were generated by data fitting method. Two-phase correlation analysis was used for dimensionality reduction of high dimensional evaluation features. …


Modeling And Research Of Global Allocation Policy In Cascading Failures, Chongjie Dong Jan 2019

Modeling And Research Of Global Allocation Policy In Cascading Failures, Chongjie Dong

Journal of System Simulation

Abstract: In reality, the global loads of network usually alter when the structure and function of network change by a list of attacks. Based on this, the paper defines extra loads of the normal node inversely proportional to the distance of failure node and presents a new indicator named "diffusion step" to failure diffusion process, which uses the global allocation policy instead of neighbor or local feature of node. By simulating scale-free network, small-world network and random network, the average results of network show that the scale-free network has strong ability to resist failures. When the influence of global allocation …
