The effects of preference revelation on allocational and Pareto efficiency are studied in a multi-attribute reverse English auction. Multi-attribute reverse auctions have been proposed as market institutions for electronic request for quotation buying processes. Preference revelation is a crucial question in multi-attribute reverse auctions in terms of the efficiency of auction outcomes. Result...

In this paper, we present an agent which is able to negotiate the buying and selling of imperfectly sustitutable goods in a double auction style market. Two goods are said to be imperfectly substitutable if a buyer can use either of them, but prefers one over the other. For example, an electronics manufacturer using a RAM chip can use many suppliers to do this but may be willing to pay a premiu...

In this paper, we develop a secure multi-attribute procurement auction, in which a sales item is defined by several attributes called qualities, the buyer is the auctioneer (e.g., a government), and the sellers are the bidders. We first present a Vickrey-type protocol that can be used for multi-attribute procurement auctions. Next, we show how this protocol can be executed securely. key words :...

As an alternative to the price-based traditional auction model, the multi-attribute auction model is an integrated model requiring the simultaneous trade of different types of attributes as the sellers and buyers deal. As a result, the design and modeling of the auction mechanism have become very difficult. This paper proposes a multiattribute auction model using the dominance-based rough sets ...

Multi-attribute auctions allow agents to sell and purchase goods and services taking into account more attributes besides the price (e.g. service time, tolerances, qualities, etc.). In this paper we analyze attributes involved during the auction process and propose to classify them between verifiable attributes, unverifiable attributes and auctioneer provided attributes. According to this class...

The emergence of auction that supports bids characterized by several attributes is one of the most recent evolutions within auction theory. This paper introduces the multi-attribute and transaction cost into the on-line auction, proposed by Lavi and Nisan. Different from the traditional on-line auction, the buyer makes decision only based on the bids, when each bidder comes one by one. We propo...

Auction models and protocols are found efficient in managing resources allocation, which are a key technology in grid computing system. In this paper, a new multi-attribute multi-round reverse auction is proposed, and related reverse auction based protocols are designed. The resource user’s satisfaction degree is introduced into the traditional grid resource allocation problem to help the grid ...

Multi-attribute auctions play a very important role in our economy: (i) they are widely used in industry procurement; (ii) many markets for services are organized in a form reminiscent of private multi-attribute auctions; (iii) recently many Internetbased markets adopted multi-attribute structure. Multi-attribute auctions differ from standard low price auctions in that (a) a buyer chooses a win...
