Collaborative Stochastic Deterioration Modelling Methodology for Infrastructure Renewal Planning in Small to Medium Municipalities

这是Engage项目#508383-17(结束日期为2017年12月31日)的延续。基础设施解决方案公司**(ISI)是一家总部位于密西索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)是由ISI开发的一个软件**包，具有全面的数据库管理和高级分析功能，以**在多年和多约束规划**范围内确定和优化市政基础设施投资的优先顺序。该公司已经成功地与瑞尔森基础设施创新研究所(RIII)**在NSERC Engage项目上合作，为市政基础设施系统开发恶化模型。**强调下水道，Engage项目被认为是一次成功的合作，ISI和**RIII都认为应该进一步深化合作，将研究成果整合到DOT中。这项研究项目的**目标是开发一个了解风险的决策框架和模型，以应对**管理水系统的两大挑战。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。第二是制定资本规划的优化框架，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**影响、不同资产之间的跨部门互动，以及具有动态**模型更新的资产检查战略整合在一起。ISI产品的增强版本将更好地服务于市政客户管理**其基础设施资产的生命周期，包括检查、修复、**维护和资本规划中的优先顺序和优化。

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.
