基于承包商预期收益不变的不平衡报价模型

在招标实践中,通常采用最低价中标原则,使得投标人不得不压低其投标价格。基于承包商预期收益不变的不平衡报价模型,是在“工程量清单报价”的条件下,考虑到施工中工程量的变化及施工顺序的影响,体现了资金的时间价值,在保持承包商预期收益不变的前提下,通过调整各分项工程的单价,来降低工程报价,以增加中标机会而建立的。所建立的模型简单,易于操作,并配以具体的工程实例,通过计算机求得其最优解,可供承包商投标报价时参考。

Unbalanced Quote Model Based on Unvaried Expectative Benefit of Contractor

In practice of inviting bidding, the principle of lowest quoted price for winner is usually adopted, so that contractor has to depress the price. The unbalanced quote model based on unvaried expectative benefit of contractor takes account of the engineering quantity variation and construction sequence influence under the condition of engineering quantity detailed list, and embodies the time value of capital. Under the precondition of unvaried expectative benefit of contractor, the quoted price is lowered to raise the chance of winning bidding by means of adjusting unit price of each sub-project. The established mode is easy to use and enables to get optimal computational solution as a reference to contractor's bidding.
