摘要: 从信息传输不确定性的角度,研究了指挥信息系统网络的信息传输能力。将指挥信息系统网络分为物理层和逻辑层,阐述了信息传输与物理层、逻辑层之间的关系。考虑节点、链路的有效工作概率、时延、逻辑连接、物理连接等因素,使用自信息表示信息传输的不确定性,进而得到指挥信息系统网络的信息传输能力。结合作战指挥关系设计实验,实验结果反映了各种因素对信息传输能力的影响作用,表明所提出的方法兼顾了信息传输中的可达性、时效性和正确性需求。

关键词: 指挥信息系统, 信息传输能力, 不确定性, 有效传输概率

Abstract: The information transmission ability of command information system was analyzed from the angle of uncertainty. The command information system network was divided into physical layer and logical layer, and relationships between information transmission and the layers were expounded. The effective working probability of nodes and links, time delay, logical links and physical links were taken into account. The information quantity was used to measure the uncertainty of information transmission, and then the information transmission ability of command information system was educed. The experiment was designed using combat command relationship, and influences of these factors above on information transmission ability were reflected. The experimental results show that the evaluation method take the demand of connectivity, timeliness and correctness in information transmission into consideration.

Key words: command information system, information transmitting ability, uncertainty, effective transmitting probability
