指挥控制系统信息处理容量模型

A Model for Information Processing Capacity of Command and Control Systems

信息处理容量是指系统在目标信息处理的最大允许时延范围内所能同时处理的最大目标批数，它是衡量指挥控制系统信息处理能力的主要性能指标。该文以时间Ｐｅｔｒｉ网为建模工具，建立了一类典型的指挥控制系统信息处理容量模型，定量分析了信息处理容量与系统资源、系统结构和系统各功能模块任务处理时间之间的关系，指出系统的瓶颈。

Information processing capacity (IPC) is the maximum target batches that a system can process in the same time under the condition that the maximum processing delay of a target’s information is within an acceptable value.It is one of the main indices used to evaluate the information processing ability of a command and control (C 2) system.A model for the IPC of a class of typical C 2 system is built by use of the tool of timed Petri nets.The relations of IPC to system’s resource,to system’s structure,and to system’s task processing time are analyzed quantitatively.The system’s bottleneck of information processing is pointed out.
