| 中文摘要： | 变电工程项目风险管理面临复杂多变的环境和各种各样的不确定风险因素，同时由于项目管理者风险管理意识淡薄、风险控制策略选择不当、控制措施执行不到位，造成了变电工程项目质量、安全、进度等目标失控、“三超”现象发生，严重时发生爆炸、火灾等，导致人身意外伤亡事故，造成重大财产损失等。因此，变电工程项目被认为一种风险较高的建设项目，如何进行积极、有效风险管理是目前急需解决的研究课题。为有效提高变电工程项目风险管理水平，本文以项目风险管理者的视角，根据变电工程项目实施阶段的实际情况，提出基于解释结构模型（Interpretative Structural Modeling，ISM）的风险层级划分模型，结合作业条件危险性分析法LEC度量方法、风险管理和风险控制理论等，对变电工程项目风险控制进行研究。首先，对变电工程项目实施过程进行风险识别，给出涵盖16个风险因素的度量指标体系；然后，应用ISM对风险因素之间的层级划分、逻辑关系进行研究，并结合施工组织方式进行风险传递分析；其次，应用LEC方法对各项风险进行度量，给出其风险等级；最后，根据ISM层次结构等给出有针对性的风险控制策略和具体控制措施。论证分析结果表明，本文所述方法可以有效降低风险等级，减少风险可能造成的损失。本文研究具有较强的实践指导意义，为变电工程同类项目的实施提供了有益参考和借鉴。 | |
| 英文摘要： | The risk management of power transforming project faces a complex and changeable environment and various uncertain risk factors, at the same time, due to the weak awareness of risk management, improper strategies of risk control are selected, executive ability is not in place or inadequate, project objectives such as quality targets, schedule and security out of control caused by the risk factors, even serious accidents caused by explosion, fire, etc., causing significant loss of property. Therefore, the power transformation project is considered to be a high-risk construction project. At present, how to carry out active and effective risk management is an urgent research topic. In order to effectively improve the risk management level of the power transforming project, this paper is based on the project risk manager's perspective and according to the actual situation of the implementation stage of it, a model based on interpretative structural modeling(ISM) is proposed, and the ISM is used to defined the levels of the risk factors, the risk control of power transforming project are comprehensively evaluated, combined with LEC, the theories of risk management and control. Firstly, risk identification is executed and 16 risk factors are listed, the index system for risk assessment is given. Secondly, ISM is used to study the level and logical relationship of such risk factors, combined with the construction organization mode. Thirdly, risk control strategy and specific control measures is given based on the levels of ISM. Finally, a case study about a really project was used to verify the model. The results showed that the methods described in this paper can effectively reduce the risk level and the related losses. This paper has a strong practical significance, which can provide some useful references to similar power transforming projects. | |
