【摘要】:建筑工程领域大型施工企业存在数量众多、性质迥异的项目,由此造成项目风险评价过程的不确定性及评价方法的复杂低效性。文章建立了基于网络层次分析法(ANP)与决策树分类的多项目风险评价模型。在建立项目风险评价指标体系基础之上,通过ANP确定各风险因素发生的可能性及其权重。应用"康斯坦茨信息挖掘工具"KNIME软件进行决策树分类,建立多项目风险等级评价模型,快速高效的应用于后续多个新项目风险等级评估。算例验证结果表明,该模型在准确评估多项目风险因素权重、快速确定多项目风险等级方面具有较强的实用性,为大型施工企业、政务部门提供科学依据。
[Abstract]:Large construction enterprises in the field of construction engineering have a large number of projects with different nature. As a result, the uncertainty of project risk assessment process and the complexity and inefficiency of evaluation methods are caused. This paper establishes an ANP-based network analytic hierarchy process (AHP). Multi-project risk evaluation model based on decision tree classification. Based on the establishment of project risk evaluation index system. The possibility and weight of each risk factor are determined by ANP. The decision tree classification is carried out by using the KNIME software of Constance Information Mining tool, and a multi-project risk rating evaluation model is established. The model is applied to evaluate the risk levels of several new projects quickly and efficiently. The results show that the model can accurately evaluate the weight of multi-project risk factors. The quick determination of multi-project risk grade has strong practicability and provides scientific basis for large construction enterprises and government departments.
