Combining　with　the　existing　research　results,　a　satisfaction　model　of　multi-agent　system　has　been　constructed　in　this　paper　for　the　existent　problems.　The　overall　satisfaction　of　agent＇s　real-time　and　dynamic　valuation　has　been　realized　by　the　model,　and　the　model　has　the　function　of　anti-deceive　with　the　set-up　of　utility　factor　and　trigger-tactics.　At　last,　the　better　efficiency　of　the　satisfaction　model　has　been　tested　by　simulated　experiment.
