Research on Operational Effectiveness Evaluation of Network Information System Based on System Dynamics

The operational effectiveness generation of network information system is characterized by nonlinear, variable weight and multiple feedback, and the internal structure feedback relationship and operating mechanism are also extremely repetitive. Based on the theory of system dynamics, a dynamic model of operational effectiveness evaluation system of network information system with feedback loop as the core element is constructed. Taking joint border counterattack operations as an example, Vensim simulation platform was used to simulate and analyse its combat effectiveness, system contribution rate and system sensitivity. The simulation results showed that system dynamics theory had a significant effect on exploring the internal operation mechanism of network information system.
