Effective Detection Engineering Cost Price Method Based on Entropy Proportion and Fuzzy Risk Evaluation

Abstract:

For low price bidding method, how to detect the cost price has been the research difficulty and hot. Effective detection method of combination entropy decision and fuzzy risk evaluation was proposed.According to each construction unit’ project bidding risk index systems, using entropy proportion method to determine the weights, and then through the project risk fuzzy evaluation model, fuzzy comprehensive evaluation of risk value, and finally according to the size of risk value in order to determine the level of profits, and the cost was determined. The effectiveness was validated through the practical engineering cases. The method opened up that judge bidding price whether lower than the cost. While overcoming the only pursuit of winning the bid in the lowest price, regardless of the disadvantages whether lower than the cost.
