This is a continuation of Engage Project #508383-17 (End Date was 2017-12-31). Infrastructure Solutions Inc.**(ISI) is a Mississauga-based consulting and software development company providing asset management**solutions to Canadian municipal governments. Decision Optimization Technology (DOT) is a software**package developed by ISI with comprehensive database management and advanced analytical capabilities to**prioritize and optimize municipal infrastructure investments over a multi-year and multi-constraint planning**horizon. The company has successfully collaborated with Ryerson Institute for Infrastructure Innovation (RIII)**on an NSERC Engage project in developing deterioration models for municipal infrastructure systems.**Emphasizing on sewer pipes, the Engage project was considered a successful collaboration, and both ISI and**RIII believe that the collaboration should be further deepened to integrate the research outcomes into DOT. The**goal of this research project is to develop a risk-informed decision making framework and model to address**two major challenges of managing water systems. The first is the development of deterioration models to**capture physical deterioration trends in water system's linear assets with the ability for extension into other**asset types. The second is the development of an optimization framework for capital planning integrating**lifecycle cost analysis, risk analysis, effectiveness of maintenance and rehabilitation technologies, network**effects, cross-sectoral interactions among different assets, and strategies for asset inspection with dynamic**model updating. The enhanced version of the ISI product would better serve its municipal clients in managing**the lifecycle of their infrastructure assets, including prioritization and optimization in inspection, rehabilitation,**maintenance, and capital planning.

这是Engage项目#508383-17的延续（结束日期为2017年12月31日）。Infrastructure Solutions Inc.** (ISI)是一家总部位于密西沙加的咨询和软件开发公司，为加拿大市政府提供资产管理 ** 解决方案。决策优化技术（DOT）是ISI开发的一个软件包，具有全面的数据库管理和先进的分析能力，可以 ** 在多年和多约束规划 ** 范围内优先考虑和优化市政基础设施投资。该公司与瑞尔森基础设施创新研究所（RIII）** 在NSERC Engage项目上成功合作，为市政基础设施系统开发退化模型。强调下水道管道，参与项目被认为是一个成功的合作，ISI和 **RIII都认为，合作应进一步深化，以整合研究成果到DOT。该研究项目的目标是开发一个风险知情决策框架和模型，以解决 ** 水系统管理的两个主要挑战。首先是开发劣化模型，以捕捉水系统线性资产的物理劣化趋势，并能够扩展到其他资产类型。第二个是开发一个资本规划的优化框架，该框架将 ** 生命周期成本分析、风险分析、维护和修复技术的有效性、网络 ** 效应、不同资产之间的跨部门相互作用以及具有动态 ** 模型更新的资产检查策略整合在一起。ISI产品的增强版将更好地服务于市政客户管理基础设施资产的生命周期，包括检查、修复、维护和资本规划的优先级和优化。
