Abstract: According to C⁴ISR architecture,the development and configuration on the equipments of the complicated system are researched by using the theory and method of System Engineering.Firstly, differential equation and logistic model are used to establish the developing model for each kind of equipment. Then,the equilibrium points and stability are analyzed,and the factors of the stability are also introduced. Finally,by using Matlab the equations are solved,and it results in a tendency chart.This method can provide theory reference and decision gist for actual application.
