备注

目前,国内对于视频安防监控系统电气施工领域的评估,无论是理论还是方法上都比较欠缺,多由一些专家及现场安全员凭经验得出结果,这样既缺乏科学性又有很大的局限性.提出一种组合式评价方法,即根据视频安防监控系统构成及施工工艺,采用HAZOP对系统电气施工节点进行定性分析,并得出偏差产生的原因和结果,在此基础上,结合层次分析法建立评价指标体系,利用差异性系数改进的组合赋权法对指标权重进行优化,采用等级比重法确定指标的隶属度,由专家打分建立模糊评判矩阵,通过模糊综合判断理论算法得出结论.将该方法运用于实际工程项目进行系统施工质量评价,可分析出系统整体质量等级并能准确定位施工质量较差的指标和制定对应的安装技术措施,验证了其科学性、实用性,为系统电气施工质量评价提供了一定的理论基础.

At present, the domestic field of video surveillance and control system for the assessment of the electrical construction, either in theory or in method is relatively lacking some experts and on-site safety personnel experience which is obrisously unscientific and limited. This paper presents a combined evaluation method, that is, according to the structure and construction technology of video surveillance and control system, HAZOP is used to conduct qualitative analysis of the system electrical construction node, and the reason and result of the deviation are obtained. On this basis, combined with analytic hierarchy process evaluation index system, the weight of indicators is optimized by using the combination weighting method with improved diversity coefficient. The grade weighting method is used to determine the membership degree of the indexes. The experts' score is used to establish the fuzzy evaluation matrix, and the conclusions are obtained through the fuzzy comprehensive judgment theory algorithm. The method is applied to the actual construction project to evaluate the construction quality of the system, which can help analyze the overall quality level of the system and accurately locate the indicators of poor construction quality and make corresponding installation technical measures. This verifies its scientificity and practicability. Electrical construction quality evaluation provides a certain theoretical basis.
