The Canadian Water and Wastewater Association (CWWA) reported that there were more than 112,000 kilometers of water mains in Canada, which required $12.5 billion over 15-year (1997-2012) period to rehabilitate the existing (deteriorated) and construct new water mains in order to cope with the projected population growth. Although there are several research works, reported in the literature, on construction and rehabilitation of municipal infrastructure systems, further investigation is needed to study the most cost-effective rehabilitation method(s) for various elements of water system and to optimize the allocation of municipal resources (budget, labor, and equipment) to water system projects. The applicant, capitalizing on his previous and ongoing research works on infrastructure management systems, is planning to investigate the area of underground municipal infrastructure systems from construction and rehabilitation perspectives. The proposed research involves designing a decision support system (DSS) in order to manage water main projects. The DSS includes the following three main activities: (a) design a Monte Carlo simulation model that selects the most cost-effective rehabilitation method considering impact on environment and the total cost through the life cycle of a project; (b) establish a priority index model that optimizes budget allocation to water main projects using multi-attribute utility theory; and (c) develop a resource allocation model in order to optimize the allocation of municipal resources (water emergency and repair crews (labor and equipment)) among projects. This resource model will be developed by integrating web geographical information system (Web-GIS) with multi-objective goal optimization models. The DSS will facilitate, using the web as a platform, communication among various levels of municipal management and accelerate their decision-making process. The proposed research will contribute to the state of the art of water main rehabilitation management in both academic and industrial sectors. This research is deemed essential to the three government tiers (municipal, provincial, and federal) to meet public needs of quality of life, safety, and health.

加拿大水和废水协会报告说，加拿大有超过112，000公里的水管，在15年（1997-2012年）期间需要125亿加元来修复现有的（恶化的）水管和建造新的水管，以科普预计的人口增长。虽然有几个研究工作，在文献中报道，对市政基础设施系统的建设和恢复，需要进一步调查，研究最具成本效益的恢复方法（S）的水系统的各种元素，并优化市政资源（预算，劳动力和设备）的分配给水系统项目。申请人利用其以前和正在进行的基础设施管理系统研究工作，计划从建筑和修复角度调查地下市政基础设施系统领域。建议的研究涉及设计一个决策支持系统（DSS），以管理水的主要项目。该决策支持系统主要包括以下三个方面的工作：（a）设计了一个蒙特卡罗模拟模型，该模型在考虑工程对环境的影响和整个生命周期的总成本的情况下选择最经济的修复方法：（B）建立了一个优先级指数模型，该模型利用多属性效用理论优化了干线工程的预算分配;以及（c）开发一个资源分配模型，以便优化市政资源（水应急和维修人员（劳动力和设备））在项目之间的分配。该资源模型将通过集成网络地理信息系统（Web-GIS）和多目标优化模型来开发。DSS将利用网络作为平台，促进各级市政管理部门之间的沟通，加快其决策进程。拟议的研究将有助于在学术界和工业界的水管修复管理的艺术状态。这项研究被认为是必不可少的三级政府（市，省，联邦），以满足公众的生活质量，安全和健康的需求。
