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，排水系统的大部分部件被掩埋的事实使公众(他们的税收有助于其扩建和维护)对其运行知之甚少，更重要的是，使其更换变得昂贵、耗时，并对居民的日常活动造成严重干扰。因此，现代市政当局拨出大量预算用于排水系统的运行维护，以遏制老龄化的后果。就加拿大埃德蒙顿而言，运行维护一揽子计划包括六项主要活动：(一)低压冲洗、(二)高压冲洗(也称为喷射)、(三)闭路电视检查、(四)目视检查、(五)集水池清洗和(六)液压机械清洗(也称为链式连杆)。本研究项目旨在通过以下目标改进合作伙伴的排水维护业务：(1)对闭路电视数据收集过程进行时间研究；(2)闭路电视监测；以及(3)基于可靠性的闭路电视检查调度。拟议的研究对行业实践和加拿大社会的好处包括：(1)培训从业人员，使他们更好地了解在现场完成的每项任务将如何影响整体生产率；(2)行业合作伙伴的管理做法及其员工心态的积极变化；(3)提高维护流程的成本效益；(4)更有效地利用排水维护资源，如人力、水和燃料；以及(5)提高服务水平和客户满意度。

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.
