Interactive　learning　environment　usually　offer　a　user-friendly　interface.　This　allows　inexperienced　users　fast　access　to　the　key　point　of　knowledge,　because　they　have　experience　in　making　decisions　in　simulators.　Thus,　they　are　not　only　able　to　examine　the　results　of　their　decisions　but　also　the　causes　of　these　results.　This　article　will　explain　the　principle　and　process　of　interactive　learning　environment　by　system　dynamics　for　business　students.　Furthermore,　the　competition　of　supply　chains　is　used　as　the　designing　case.　effectiveness　of　transparency　were　tested.　Results　show　the　necessity　for　further　research　and　collaboration.
