Risk Evaluation Of Construction Project Bidding Based On Cloud Model And Grey Correlation Degree

Construction project with large investment, long construction period and high technical requirements, management difficulty big, in the whole construction process, there are many uncertain factors in relation to project success. Tender offer is a decisive construction prophase work, the whole bidding quotation stage will face all kinds of uncertainty, it will be affected by the project’s own type, size, technical requirements, the influence of such factors as also from bidding companies, owners and environmental factors, etc. Tender offer greater risk analysis and the research of the construction engineering, helps to find early risk, take effective measures, to improve our country contracting enterprise risk control ability and the price level, has important practical significance.This study mainly introduce construction engineering bid price quotations in front of related concepts, requirements, procedures, and characteristics of risk and risk evaluation concept and the content, purpose, method and process of risk identification, etc, on the basis of theoretical knowledge, through the way of literature review and expert interview, the tender offer, which can identify risk factors and build the bid price quotations of the present study risk evaluation index system. Index system including enterprise factors, project factors, environmental factors and the owner 4 first-level indicators, economic strength, and further divided into enterprise construction ability, the types of projects, project size 22 secondary indexes, etc. Using cloud model and cloud of uncertainty reasoning rules, the tender offer risk factors index quantitative to qualitative description of the specific values, in order to realize the reasonable transformation between qualitative concepts and their quantitative;, in turn, combining the theory of grey correlation degree, put forward based on cloud model and grey correlation degree of construction project bidding quoted price risk evaluation method, the grey correlation analysis, the weight of each risk index factor, the sort key risk factors are obtained.The study has found that the weight of factors is the largest, followed by the project factors, environmental factors and owners, 22 secondary indicators affect the biggest is inflation. According to the evaluation results of instance, through the whole decision-making from the project, project participants, the influence factors of the fundamental aspects of analysis, the results showed that all conform to the actual situation of project decision-making, project construction. Results indicate that, compared with the previous evaluation methods, cloud model combined with grey correlation evaluation method takes into consideration the bids of the fuzziness and randomness of risk factors in the risk assessment to the evaluation results, the influence of scientific and reasonable evaluation results, the evaluation method in the risk assessment of construction project bidding quotation with strong feasibility and validity...
