Combining field data and computer modelling to improve the productivity of CCTV data collection and analysis

在最关键的市政基础设施中，排水系统的大部分组件都被埋在地下，这使得公众（他们的税收有助于其扩展和维护）对其操作的了解较少，更重要的是，使其更换过于昂贵，耗时，并且对居民的日常活动具有高度破坏性。因此，现代市政当局拨出大量预算用于排水系统的运营维护，以遏制老化的后果。就加拿大埃德蒙顿而言，一揽子业务维护包括六项主要活动：㈠低压冲洗; ㈡高压冲洗（也称为喷射）; ㈢闭路电视检查; ㈣目视检查; ㈤清理集水池; ㈥水力机械化清理（也称为链式连枷）。该研究项目旨在通过以下目标改善合作伙伴的排水维护操作：（1）闭路电视数据收集过程的时间研究;（2）闭路电视监控;（3）基于可靠性的闭路电视检查计划。拟议的研究对工业实践和加拿大社会的好处包括：（1）培训从业人员，使他们更好地了解现场执行的每项任务如何影响整体生产力;（2）工业伙伴的管理实践和员工的心态发生积极变化;（3）提高维护过程的成本效益;（4）更有效地运用人力、水和燃料等资源进行排水系统维修;及（5）提高服务水平和顾客满意程度。

Among the most critical of municipal infrastructure, the fact that the majority of the drainage system's components are buried makes the public, whose taxes contribute to its expansion and maintenance, less aware of its operation and, more importantly, renders its replacement prohibitively expensive, time consuming, and highly disruptive to residents' daily activities. As a result, modern municipalities allocate substantial budgets to operational maintenance of the drainage system in order to curb the consequences of aging. In the case of Edmonton, Canada, the operational maintenance package includes six major activities: (i) low pressure flushing, (ii) high pressure flushing (also known as jetting), (iii) closed-circuit televised inspection, (iv) visual inspection, (v) catch basin cleaning and (vi) hydro-mechanized cleaning (also known as chain flail). This research project seeks to improve the partner's drainage maintenance operations through the following objectives: (1) time study of the CCTV data collection process; (2) CCTV monitoring; and (3) reliability-based scheduling of CCTV inspection. Benefits of the proposed research to industry practice and to Canadian society include the following: (1) train practitioners to better understand how every task performed on site will impact the overall productivity; (2) positive change in the management practices of the industrial partner and in the mindset of its employees; (3) improved cost effectiveness of maintenance processes; (4) more efficient use of resources for drainage maintenance, such as man-power, water, and fuel; and (5) increased level of service and customer satisfaction.
