Internet-based Optimal Auction Mechanism Design

As an effective resource allocation mode and price seeking mechanism, auctions have been expanded from the traditional local auctions to the online auctions. It has been an important e-business pattern by means of the extensive transaction means with little limited and the rapid increasing of transaction sum. Therefore, researches on online auctions show the essentiality more and more. By comparative analyze aiming at the online auctions, we find that some mechanisms of online auction need to be further improved. In recent Years, the design of Auction Mechanism is also A Research Hot Spots of online auction.At first, the paper based on the auction formalism in Onsale, Inc. an Internet-based auction house, Always supplies in the auction assigns under the condition. Based on the on-line auction quantity to the reward function influence theory, regards as its auction time the variable, improved the way of the auction time determination, has obtained optimal interest brand new train of thought.Second, used the rough sets'attribute reduction theory to research the multi- attribute on-line auction proposed one new algorithm with which how do win. This algorithm surpasses the algorithm which obtains based on the fuzzy sets theory.In this paper, ripping this theory by means of discussing online auction mechanism and providing theoretical references for designing mechanisms of online auction.
