建设项目的投标阶段，影响投标方案的因素多、受外界影响大，为此很难找出一种准确、便捷的方案比选手段。应用 BP 神经网络正反馈运算理论进行三种实例投标方案比选，得出最佳投标方案，阐述一种既便捷又精确的方法来进行投标方案比选。该方法不仅具有比选方案的基本功能，还具有风险预估的优势。

Multiple factors may influence the bidding scheme at the bidding stage of the construction project,which makes it difficult to determine an accurate and convenient bidding comparison meth-od.The best bidding scheme of three real /practical bidding alternatives was determined via neural network positive feedback back propagation (BP)computation.An accurate and convenient compar-ison method of bidding schemes was discussed.The results indicate that the method not only has comparative function,but also has the advantage of risk estimates.
