Abstract: A system and method for optimizing transactions in an e-marketplace. An e-marketplace optimization server couples to a plurality of participant computers through a network. The server hosts a site which provides the e-marketplace where goods and/or services are bought and sold among participants. The server also includes a transaction optimization program which mediates a transaction among the participants which best serves the needs of the participants. Each of the participant computers provides transaction information to the server, including constraints and/or objectives related to the transaction. The transaction optimization program uses the transaction information to produce transaction results for the participants, including an optimized transaction specifying which of the participants are included in the transaction, and the terms of the transaction, which optimizes any objectives of the included participants subject to any constraints of the included participants.

Abstract: A system and method for optimizing transactions in an e-marketplace. An e-marketplace optimization server couples to a plurality of participant computers through a network, each of which is operated on behalf of a participant. The server hosts a site which provides the e-marketplace where goods and/or services are bought and sold among participants. The server also includes a transaction optimization program which mediates a transaction among the participants which best serves the needs of two or more of the participants. Each of the participant computers provides transaction information to the server, including constraints and/or objectives related to the transaction.
