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

这是参与项目#508383-17的延续（结束日期为2017-12-31）。Infrastructure Solutions Inc.**(ISI)是一家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）是一个由ISI开发的软件包，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的范围内优先考虑和优化市政基础设施投资。该公司已成功地与瑞尔森基础设施创新研究所(RIII)**就NSERC Engage项目开展合作，开发市政基础设施系统的退化模型。** Engage项目强调下水道管道，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，将研究成果融入DOT。本研究项目的目标是开发一个风险知情的决策框架和模型，以解决管理水系统的两个主要挑战。首先是开发退化模型，以捕获水系统线性资产的物理退化趋势，并能够扩展到其他类型的资产。二是构建资本规划优化框架，整合全生命周期成本分析、风险分析、维修和修复技术有效性、网络效应、不同资产之间的跨部门互动、资产检查策略和动态模型更新。ISI产品的增强版将更好地为市政客户管理其基础设施资产的生命周期，包括检查、修复、维护和资本规划的优先级和优化。

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.
