Based on the background of engineering construction bidding project, this paper analyses the evaluation indicator system firstly, and then establishes evaluation indicator system for the analysis of evaluation risks on the basis of the existing evaluation system, which is referred to [7], finally puts forward a kind of risk analysis model which bases on evaluation results to identify project risk point.
Fig 2 Risk points division Application result analysis of the model In order to apply the risk analysis model to the engineering construction bidding activities and achieve early warning of the project, we need to complete the following tasks: 1) to obtain historical evaluation data and the data pretreatment; 2) using C4.5 algorithm to establish the classification decision tree; 3) in view of the specific project for data analysis and risk point judgment; 4) in view of the risk point analysis, giving risk warning or putting forward related suggestions.
