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.
