Based on the work of Krishna and Rosenthal (1996) about combinatorial auctions bidding equilibrium analysis and Che(1993)’s research about one-unit multi-attributes auctions, we construct a multi-attributes procurement simultaneous auction for 2 objects, through a first-score(price), sealed-bid format. There are two kinds of bidders: simple bidders and a diverse bidder considered in this model. Each simple bidder is interested in only one of the objects, while the diverse bidder is interested in both. With some further assumptions, we finally obtain the equilibrium bidding strategies for the both two kinds of bidders.
