Abstract:Procurement combinatorial auction means procurement for various items in enterprises or government which is implemented by combinatorial auctions.One of the most important characteristic of mechanism design for procurement combinatorial auction is the system allocation efficiency,which is meaningful and unique in procurement combinatorial auctions.The mechanism should not only consider suppliers-bidders' profits,but also the buyer-auctioneer's profit.However,the cost function is usually the bidder's private information,this information influences the allocation efficiency.Considering this,we propose MA-VCG-PQ,an efficient multi-attributes procurement combinatorial auction,in which agents could bid for set of items with direct price-quality bid,without eliciting cost function information.Besides incentive compatible,the mechanism also holds the budget balance and individual rationality.
