The Research On Risk Evaluation System In BOT Project Of Highway

Highway has played a more and more important role in national economical development of China. But highway construction cost enormous funds. Particularly, funds for current infrastructure in China are out of demand while BOT financial pattern used in highway construction has provide a new approach for funds solution.However, BOT project of highway is spring up shortly in our country, many of aspect is very juvenile, correlative experience is await summarized. Hereinto, the problem of risk in BOT project is a important aspect. None but resolve the risk correctly,can insure the BOT project of highway put into practice successfully.The paper has just based on the risk in BOT project of highway, discussed the evaluation correlative problem of the risk. The study mainly includes the following contents:Firstly, the paper has started with the correlative theory of risk evaluation on BOT project of highway, introduced amply the mainly contents, concept of project risk, sort and the aim of risk evaluation, effect, standard and processes of evaluation, anatomized the object and the characteristic on risk in BOT project of highway. Meanwhile, analyzed and classified emphatically the risk factor in project. Besides, expatiated evaluation methods and probability and statistic of risk evaluation in BOT project of highway, concluded the confirm methods of risk classification in BOT project.Afterwards, the paper has combined the correlative theory of Grey System and Analytic Hierarchy Process, recounted the principle of establish the Grey Hierarchy Evaluation, confirmed the index aggregate's proportion of risk factor, and on the basis of these, established the model of Grey Hierarchy Evaluation, and evaluated the risk factor in various hierarchy of highway BOT project.Finally, the paper combined the case of LiTan BOT project of highway, utilized the model of Grey Hierarchy Evaluation to analyze. The paper find the scientific and feasible result of evaluate. It can provided the gist of decision-making for the project manager.
