Abstract: Calculating the bid price is a complex task which is combined with technique and economy. It has crucial effect on whether the contractors can get the project. Bidders can use many kinds of methods to calculate the bid price and unbalanced bidding is a common method. But many mathematic and linear methods are exparte. To make the bidder’s bid price more competitive, the author applied Fuzzy synthesis evaluation and the unbalanced bidding coefficient to set up a model. This model can solve the pr

摘要： 工程的投标报价是一项技术和经济相结合的复杂工作，投标报价对能否中标具有决定性作用。为了使投标者 的报价更具有竞争性，本文运用模糊综合评判法，引入不平衡报价系数，综合考虑工程项目各种情况，最终得出总 报价。该模型解决了原有方法中定性与定量评价不能很好结合的问题，使不平衡报价在科学性以及实用性等方面 得到了改进。
