Abstract

Condition assessment of aging infrastructure is a growing concern all over the world. A systematic performance assessment is a pre-requisite for effective asset and infrastructure management. Accordingly, this article develops an integrated approach for the performance assessment of the municipal infrastructure. The main objectives are to develop an approach to assess, measure, and combine the performance levels of water, sewer, and road infrastructure and then integrate those values into a performance index. The methodology involves developing assessment criteria from literature and using interviews with professionals. A series of workshops was conducted with professionals in Canada. Throughout the workshops, questionnaires were collected based on the analytic hierarchy process (AHP) technique. Using AHP and fuzzy set theory, data was aggregated, and the results were developed. The analysis proved that the road roughness rating has the highest impact on the performance level followed by the number of breaks that occurred within the water network. Furthermore, the developed integration model was validated by professional engineers working in the field and has shown potential in terms of providing a reliable assessment of the overall state of the infrastructure.

摘要

老化基础设施的状况评估是全世界日益关注的问题。系统的绩效评估是有效资产和基础设施管理的先决条件。因此，本文开发了一种用于市政基础设施绩效评估的综合方法。主要目标是开发一种方法来评估、测量和结合水、下水道和道路基础设施的性能水平，然后将这些值整合到性能指数中。该方法涉及从文献中制定评估标准并使用与专业人士的访谈。与加拿大的专业人士一起举办了一系列研讨会。在整个研讨会期间，问卷调查是基于层次分析法 (AHP) 技术收集的。使用层次分析法和模糊集理论，数据被聚合，并开发了结果。分析证明，道路粗糙度等级对性能水平的影响最大，其次是水网内发生的中断次数。此外，开发的集成模型得到了在该领域工作的专业工程师的验证，并在提供对基础设施整体状态的可靠评估方面显示出潜力。
