Abstract: Systems for negotiation support. First and second negotiation agent modules respectively receive multiple first proposals, calculate preference scores (PSs) for each first proposal using utility models and select a portion of the first proposals as second proposals in descending order according to the calculated PSs therewith. The negotiation management module receives the second proposals from the first and second negotiation modules, and generates third proposals according to the received proposals. The first and second negotiation agent modules respectively receive the third proposals, calculate PSs for received proposals using utility models, and arrange the third proposals in descending order according to PSs therewith to generate voting results. The negotiation management module receives the voting results, and generates a final agreement according to the received voting results.

Abstract: Methods for auction negotiation support executed by a negotiator agent module are provided. The best bid corresponding to a product/service and a total number of negotiator agent modules placing the best bid are received. It is determined that a bid is placed by a following strategy or an exceeding strategy. The following strategy indicates that, when the received best bid is not equal to the prior bid placed by the negotiator agent module, the negotiator agent module places the bid equal to the received best bid. The exceeding strategy indicates that, when the inverse of the total number of negotiator agent modules placing the best bid is lower than a predetermined threshold, the negotiator agent module places the bid advanced to the received best bid.
