Abstract：Research purposes: The exploration was made on the component elements of integral bidding and methods for assessing and accepting or rejecting the uncertainty of the elements so as to provide numerical procedure for offer for compound bidding.
Research methods: The collected data on offer for integral bidding were sorted and made into specimens through using basic knowledge of statistics. The regularity of distribution of variable data was found and the proportionate relation among variable data was calculated through statistics, comparison and analysis of the data in specimen. The research was made mainly on the proportionate relation and numerical value that occurred frequently. The checking calculation was made to them by putting them in similar specimen in order to find out the universally typical value or central value. The general research thought was to know unknown probability through calculating known variable data and explore other unknown data from known probability.
Research results: The methods of calculation and identity were presented for important parameters that influenced the offer for integral bidding and the scope of upper and down limits was defined for offer range, good offer range and optimum offer range.
Research Conclusions: When determining the final offer for integral bidding by adopting computing method, the enough specimens had to be collected. More specimens you collected and more accurate offer you got. The expected result of offer could not be obtained with the data obtained from a few specimens.
