The theory of auctions has ignored the fact that often auction designers, not the principal, design auctions In a multi attribute auction, the auction designer may bias his subjective evaluation of quality or distort the relative weights of the various attributes to favor a specific bidder, an ancient concern in the procurement of weapons, in the auctioning of government contracts and in the pu...

The use of e-Auction services has been increasing in recent years. Security requirements in conducting eAuctions are mainly bid privacy, anonymity and public verifiability. Most of the secure protocols concentrate on privacy and anonymity, which are achieved through bidder-resolved multi-party computation, assuming two or more trusted third parties, either through numerous auctioneers or with a...

To build a new bidding model of multi-attribute online auctions, this paper introduces the concepts of multi-type attribute and nonlinear function. The model can measure the effect of the attributes in auctions by adopting the normalized method of weighting and it will set the stage for the purchasers to evaluate suppliers in the procurement management. Furthermore, this paper developed an appl...

The use of reverse auctions for procurement activities has grown tremendously over the last several years. The majority of these auctions use a single dimension (price) format while providing constraints on non-price attributes such as quality and lead time. In this research, we present an auction mechanism for a buyer whose utility function is known and dependent on three attributes: price, qu...

In multi-attribute procurement auctions with multiple objects, the auctioneer may care about the interplay of quality attributes that do not belong to the same item – like each item’s delivery time, if all items are needed at once. This can influence the performance of the auction mechanism. We generalize the Ausubel-Milgrom ascending proxy auction to such an environment and show that the main ...

T majority of reverse auctions for procurement use a single-attribute (price) format while providing constraints on nonprice attributes such as quality and lead time. Alternatively, a buyer could choose to conduct a multiattribute auction where bidders can specify both a price and levels of nonprice attributes. While such an auction may provide higher theoretical utility to the buyer, it is not...

The vast majority of electronic markets have been based purely on a single variable (price) as the factor that determines ‘the winner’. Multi-attribute auctions are likely to be more appropriate for procurement scenarios where factors other than price need to be considered in determining the outcome. Nevertheless, there is a scarcity of empirical research on multi-attribute electronic auctions....

This paper provides an optimal auction mechanism design for automated agents conducting auctions, for example, auction houses on the web. In particular, we consider auction protocols that include two major features; multi-attribute items and a deadline rule. Three different protocols were analyzed. For each protocol a mechanism was developed that enables the auctioneer agent to compose an optim...
