Analysis on price adjustment coefficient of unbalanced bid model under the pricing pattern of Bill of Quantities

摘要

According to the characteristic of “quantity price separation” under the pricing pattern of Bill of Quantities [1], this article utilizes the fuzzy synthesis judgment method, analyzes the price adjustment coefficient of unbalanced bid liner programming model which is established basing on the time value of capital. And then it gives the fuzzy mathematics model of the price adjustment coefficient of unbalanced bid of the subprojects. This model can change people’s subjective qualitative analysis into quantitative analysis. It also can make the determination of the price adjustment coefficient have some certain comparability and uniformity, reduce the affection of subjective decisions. Compared to other articles which study unbalanced bid, they generally determine the price adjustment coefficient to a subjective data, but the mathematics model established in this article, can help contractors receive more reasonable unbalanced bid price adjustment coefficient under the pricing pattern of Bill of Quantities. This can make sure contractors’ exorbitant profit and reduce the risk of unbalanced bid.
