Optimal design of auction is one of hot research topics in the auction theory. During recent years, shill bidding has increased substantially with the explosion in the number of online auctions. This paper designs the optimal online auction with shill bidding and open reserve price. Many optimal auction models have assumed that the number of potential bidders is constant and known. And in these optimal...
To overcome the drawbacks that individual preference information for uncertainties is rarely considered in current complex alternative ranking methods usually resulting in unreasonable alternative rankings, an approach to rank complex alternatives based on behaviors is presented by means of prospect theory. The presented approach introduces a new analysis structure to decompose a complex problem into...
The individual preferences for gains, losses, and uncertain events, which are first proposed by prospect theory, are rarely considered in current MADM methods. To solve this problem, a MADM alternative ranking approach under uncertainty is presented. The presented approach proposes a method for eliciting individual preferences for gains, losses and uncertain events by using the trade off method and...
To solve the problems that the optimal prospect is usually selected questionably in conventional methods resulting from uncertainties existing in subjective preference judgments, an approach to select efficient prospects is presented by means of a small quantity of relatively accurate information. The presented approach uses the trade off and the certainty equivalent methods to elicit individual preferences...
