Research and Application of GA-FAHP in Project Bid Evaluation

The bidding system engineering contract model is widely used by international and domestic construction projects , is a rich competitive procurement is an important manifestation of the market economy . Numerous aspects of the bidding activities , bid evaluation center and key aspects of the construction project bidding . Scientific evaluation methods conducive to the orderly development of the market . Choose a scientific and reasonable evaluation methods are important issues related to the project ultimately achieve success . Traditional evaluation methods are mostly subjectivity , qualitative analysis , quantitative analysis , it is difficult to fully grasp today's market diversification . Therefore, starting from perfect bid evaluation theory , conducted a comprehensive analysis of the construction project evaluation methods , combined with intelligent computing theory , get a new the bid evaluation decision-making method that improved genetic algorithm fuzzy analytic hierarchy process . Traditional analytic hierarchy process based on the combination of fuzzy evaluation theory , to summarize the factors that affect the construction project bid evaluation , classification , hierarchical processing , the establishment of a construction project bid evaluation index system and the relative importance of each indicator of comparative judgment matrix ; the same time , the introduction of improved genetic algorithm , heavier on the right to the Evaluation Indicators solved , get more reasonable , effective bid evaluation index weight . Finally, an example to verify the reasonableness of the evaluation system and bid evaluation index weight . Fuzzy evaluation principle , be relatively satisfied with the successful units , to provide a reference for the decision-making of policy makers .
