The Construction Of The Early Warning System Of International Engineering Contract

The international engineering contract is an enterprise full of risk. Therefore the risk management is critical to them. It has been the focus problem that people pay attention to for a long time.The current international engineering contract risk management studies are mainly focused on project risk identification and assessment, but neglect the key project performance indicators for early warning, and the changing risk factors have not been conducted timely follow-up and feedback, which resulting in unable to process case of the risk and make effective pre-control, but can only be conducted after the disposition of passive and remedies to guard against the risk , and missed opportunities to guard against the risk. So the thesis tried to strike up an early warning and management mechanism in order to carry on risk control and management.Risk identification & analysis, early warning and risk countermeasure make up the early warning system of the international engineering contract. These three parts compose a circle.First, carry on risk identification and analysis to the international engineering to find out the risk factors that influence the project;Second, based on the analysis of domestic and foreign relevant literature, built up the early warning system index; Applied quantitative analysis and qualitative analysis methods to measure the weight and influence of the risk factor. As the international engineering's risk are fuzzy, uncertain, and not exactly defined, fuzzy comprehensive evaluation becomes a new method to solve those questions. To improve the insufficiency of the existing fuzzy comprehensive evaluation method, this paper established an improved risk evaluation model which introduces the fuzzy AHP method to count the relative weight of each risk factor, and it has fully considered the fuzziness of expert's judgment.Finally, engineering contract early warning system had been built up .According to the results of the early warning, adopt the valid countermeasures to risk sending out early warning signals to guard against and evade the risk. The paper has carried on an real case to the West Africa road project. The case results show that the risk early-warning system has set up a theoretical practical significance.
