Today,　within　the　field　of　multi-agent　systems,　the　theory　of　argumentation　has　become　instrumental　in　designing　rich　interaction　protocols　and　in　providing　agents　with　a　means　to　manage　and　resolve　conflicts.　However,　to　date　much　of　the　existing　literature　focuses　argumentation　models　based　on　two　agents　and　tends　to　overlook　the　influence　on　knowledge　base　and　the　relationship　between　different　negotiation　processes.　To　end　this,　this　paper　presents　an　argumentation-based　one-to-many　negotiation　model.　The　contributions　are　three　points:　First,　we　present　an　argumentation　model　based　on　knowledge　set　with　different　influence.　Second,　we　extend　a　protocol　based　on　dialogue　game　to　govern　the　agent　interactions　and　the　update　of　knowledge　bases　in　one-to-many　negotiation.　In　doing　so,　our　model　can　collect　the　knowledge　from　other　negotiating　partners　and　use　it　in　the　negotiation　with　another　negotiating　partner.
