Abstract: A system and method for implementing and conducting a 2-phase clock and sealed-bid auction for a multi-part product includes more than one remote computer stations connected to a network, a web server to receive and store bid information and auction parameters. The web server can include application software configured to initiate a clock phase and a sealed-bid phase. The clock phase generally includes presenting bidders with an initial price structure for the multi-part product, receiving bids from each of the bidders, storing the bids, and comparing the bids to a transition rule. The software can initiate the sealed-bid phase based on the comparison between the bids and the transition rule. The seal-bid phase generally includes providing sealed-bid parameters to the bidders, receiving a sealed-bid from the bidders, and determining an auction winner based on a selection rule.
