Abstract: Firstly the concept and components of the optimized bid for highway project was elaborated in this article, then the methods of computing these componentsespecially the methods of calculating the maximum expected profits and the aggregate losses from the risks left behind by the contractor was discussed. According to the principle of probability statistics, the model for computing the maximum expected profits was established in the article, and the ultimate expression of the maximum expected profits solving for the maximum. was found out by the method. The model for computing the aggregate lossed from the risks left behind by the contractor was set up on the basis of the principle of randomicity and vagueness. Finally the ultimate expression of the maximum bid was put forward by integrating the computation results of all components.

Key words: the Maximum Bid; the Maximum Expected Profits; the Aggregate Losses from the Risks Left behind by the Contractor; the Budget Cost for a Project; the Computing Model
