Construction Projects, Equipment Procurement Bid Evaluation Method Study

Project evaluation is the construction project bidding in the process is the most important link, it is the necessary process to decide the winner. Bid evaluation is the fundamental purpose of selected the true optimal material supply to bid, bring the greatest benefit for the enterprise, is the key to ensure the success of bidding. This paper choose the job of invite public bidding of equipment of the evaluation work as the research object, discusses in detail the evaluation index system and evaluation model selection theory, according to the characteristics of project invite public bidding, the bid evaluation method, is put forward based on the mathematical theory of fuzzy comprehensive evaluation method.This article from the equipment procurement evaluation calibration system based on knowledge proceed with, discussed in detail the engineering bid evaluation calibration procedure and the method, has analyzed our country present stage in construction project bidding in various evaluation methods advantages and disadvantages and applicability, and combining the actual situation of our country, is proposed based on fuzzy decision theory the equipment procurement evaluation method; according to the construction projects in a large number of bidding activities affect the bidding result elements was studied, established with the hierarchical structure of the evaluation index system, comprehensive as possible, complete, so that it is general, applicable to all types of equipment procurement project evaluation; in many methods to determine the weight of the key study on the analytic hierarchy process.Fuzzy logic refers to the objective things in the boundary is not clear, also of multiple valued logic, which do not belong to this is being referred to as having the objective existence of fuzziness. Fuzzy concept is the objective existence of the nature of things, is the difference between the actual existence in the middle of the transition process. Fuzzy comprehensive evaluation in fuzzy environment, considering the effect of related factors, in accordance with a purpose to make things comprehensive decision or policy.Fuzzy comprehensive evaluation method is simple and easy, scientific and good, can effectively reduce the subjective evaluation process of randomness, enhance the fairness of the bidding system, to play a better role provides a basis.
