在识别业主再分配风险清单的基础上,通过问卷调查就业主再分配风险清单中的风险事项对承包商可能产生影响的重要程度进行评价,绘制出业主再分配风险重要程度象限分布图;其次,通过建立业主再分配风险响应决策模型,揭示了承包商进行风险响应决策机理;最后,通过对业主再分配风险控制流程进行分析,描述了承包商在施工过程中对业主再分配风险的控制过程。 On the basis of identifying the owner redistribution risk list, the paper evaluates the possible impact of the risk factors on the reallocation risk list of the owner on the questionnaire and draws the quadrant distribution diagram of the importance degree of the redistribution risk of the owner. Secondly, Through the establishment of the owner redistribution risk response decision model, the risk response decision mechanism of the contractor is revealed. Finally, the control process of the owner redistribution risk is described through the analysis of the owner redistribution risk control process.
