ABSTRACT In California, wastewater systems have adapted to water conservation and drought for decades. Yet, few studies have investigated how past design assumptions influence potential mitigation and adaptation actions. This paper evaluates adaptation pathways for wastewater management in California and addresses two questions. First, are wastewater facilities experiencing challenges from mismatches in design flow values and current rates of influent flow? Second, what, if any, adaptation actions are underway or planned? To answer these questions, we compiled historical literature and conducted surveys and interviews with wastewater system managers. Approximately half of respondents indicated that they are experiencing challenges associated with changing water use rates. Aging systems have implemented many types of mitigation and adaptation actions, including operational changes, chemical additions, and facility rebuilds. California’s wastewater industry is largely pursuing an incremental adaptation pathway to manage drought and climate change. The paper demonstrates an engaged approach to research on climate change adaptation.
摘要在加利福尼亚州,废水处理系统已经适应了几十年的节水和干旱。然而,很少有研究调查过去的设计假设如何影响潜在的缓解和适应行动。本文评估了加州废水管理的适应途径,并解决了两个问题。首先,废水处理设施是否面临设计流量值和当前流入流量不匹配的挑战?第二,正在进行或计划采取哪些适应行动(如果有的话)?为了回答这些问题,我们整理了历史文献,并对废水系统管理人员进行了调查和采访。大约一半的受访者表示,他们正面临着与用水率变化相关的挑战。老化系统已经实施了许多类型的缓解和适应行动,包括操作变更、化学品添加和设施重建。加州的废水处理行业在很大程度上正在寻求一种渐进的适应途径来管理干旱和气候变化。该文件展示了一种积极参与气候变化适应研究的方法。

ABSTRACT Infrastructure asset management is concerned with the efficient and sustainable utilization of resources. There are numerous sources of uncertainties associated with the physical state of the infrastructure, climate change, and the economy. Thus, the most appropriate decision-making process to select maintenance and replacement strategies that are sustainable, economical, and safe should also be well informed in terms of risks. The decision process is formulated as a multi-objective optimization problem and exemplified the case for targeted performance levels and total costs, and solved using both Multi-Objective Particle Swarm Optimization (MOPSO) and a Non-dominated Sorting Genetic Algorithm II (NSGA-II). The results indicate that annual budget constraints have a significant effect on the Pareto front and the schedule associated with individual solutions. The proposed approach provides a useful and flexible decision-analysis tool for managers by allowing for multiple objective optimization in scheduling future interventions towards the sustainability of infrastructure.
基础设施资产管理涉及资源的高效和可持续利用。与基础设施的物理状态、气候变化和经济有关的不确定性来源有很多。因此,选择可持续、经济和安全的维护和更换策略的最合适的决策过程也应该充分了解风险。将决策过程描述为一个多目标优化问题,并以目标性能水平和总成本为例,采用多目标粒子群优化(MOPSO)和非支配排序遗传算法II (NSGA-II)进行求解。结果表明,年度预算约束对单个方案的Pareto前沿和进度有显著影响。提出的方法为管理者提供了一个有用和灵活的决策分析工具,允许在调度未来对基础设施可持续性的干预时进行多目标优化。

ABSTRACT New community-scale developments should address both greenhouse gas emissions mitigation and climate adaptation goals. This paper presents a systematic approach to energy master planning (EMP) of net-zero emissions communities via probabilistic analysis of the resilience and cost effectiveness of various energy provision portfolios (supply, conversion and storage) in early design stage. Applied in the EMP of a new university satellite campus, comprising of five buildings with mixed energy uses, both the 2050 net-zero emissions and the energy resilience objectives are met by an energy provision portfolio that consists of air source heat pumps for heating and cooling, and a combination of PV panels, purchased green power, standard (non-green) grid power, battery and thermal heat and cold storage tanks – with only a modest 6% increase in costs compared to a reference solution. The case project demonstrates the financial feasibility of a resilient energy system that also meets a net-zero emissions objective.

ABSTRACT This study aims to provide a framework to analyse future flood scenarios considering the effects of three main drivers of flood aggravation: climate change (rainfall intensification and sea level rise); unplanned urbanization; and poor maintenance of urban drainage systems. These stressors were chosen because they represent the aggravation of a natural phenomenon, the urban sprawl effects and the degradation of the drainage system. This analysis intends to make it clear what the main drivers of increasing risks are. Subsequently, a uchronic scenario is developed to analyse how adequate urban planning and infrastructure provision can contribute to a sustainable and resilient city regarding flood alleviation. The method is supported by hydrodynamic simulation. Results demonstrate that precarious urban growth without providing adequate infrastructure coverage can be even more dramatic than climate change. Otherwise, the uchronic scenario demonstrates the benefits of adequately planning cities in a sustainable way, giving lessons to this process.
摘要本研究旨在提供一个分析未来洪水情景的框架,考虑洪水恶化的三个主要驱动因素的影响:气候变化(降雨加剧和海平面上升);计划外城市化;城市排水系统维护不善。之所以选择这些压力源,是因为它们代表了自然现象的恶化、城市蔓延效应和排水系统的退化。这一分析旨在明确风险增加的主要驱动因素是什么。随后,开发了一个uchronic场景,以分析充分的城市规划和基础设施供应如何有助于建立一个可持续和有韧性的城市来缓解洪水。该方法得到了流体动力学模拟的支持。研究结果表明,如果没有提供足够的基础设施覆盖,不稳定的城市增长可能比气候变化更为剧烈。除此之外,uchronic情景展示了以可持续的方式充分规划城市的好处,为这一过程提供了教训。

ABSTRACT Innovative landscape design of sustainable and resilient infrastructure needs public satisfaction and support. In the 1990s, a new type of urban park, called ecological or sustainable park, emerged to function as green infrastructure. Precedent research reiterated the affection for the picturesque of the Americans, and their opposition to this emerging ecological landscape which tends to look messy. This research investigated if the picturesque and the messiness also matter to Thais. The questionnaire gathered opinions of 315 respondents on the appearance of Chulalongkorn University Centenary Park—a pioneering ecological park in Bangkok. The results revealed respondents’ preference for the picturesque and resistance to the messiness and poor maintenance. The picturesque convention, cues to care tactic and knowledge about nature and ecology appeared to involve in their perception of the beautiful, natural and ecologically sustainable landscapes. The research suggested strategies for designing ecological urban parks in Bangkok, which are also applicable elsewhere.
摘要可持续和有弹性的基础设施的创新景观设计需要公众的满意和支持。20世纪90年代,一种新型的城市公园出现了,称为生态公园或可持续公园,起到了绿色基础设施的作用。先例研究重申了美国人对风景如画的热爱,以及他们对这种看起来混乱的新兴生态景观的反对。这项研究调查了风景如画和混乱对泰国人是否也有影响。该调查问卷收集了315名受访者对朱拉隆功大学百年公园外观的看法。朱拉隆贡大学百周年公园是曼谷的一个开创性生态公园。调查结果显示,受访者更喜欢风景如画的地方,并抵制混乱和维护不善。风景如画的习俗、关爱策略的暗示以及对自然和生态的了解似乎涉及到他们对美丽、自然和生态可持续景观的感知。这项研究提出了曼谷生态城市公园的设计策略,这些策略也适用于其他地方。

ABSTRACT Transportation systems, such as railways, are considered critical infrastructure. It is essential to identify potential hazards that can affect the functionality of these systems and quantify metrics that can be used for resilience-informed decision-making. This paper develops an integrated probabilistic model for seismic multi-hazard risk and restoration assessment of railway systems by accounting for the effects of seismic waves propagation, liquefaction and landslide as main phenomena affecting the integrity of distributed networked infrastructure; this is done via a GIS-based user interface. An illustrative case study is then presented to assess the seismic risk and restoration of the Tehran-Sari railway in Iran. The implementation results demonstrate the capability of the presented methodology to quantify physical metrics (including combined damage state of network components, component- and system-level functionality and restoration) and economic loss. These metrics can assist officials with implementing retrofit plans to reduce loss and improve the resilience of railway system segments.
交通系统,如铁路,被认为是关键的基础设施。识别可能影响这些系统功能的潜在危险并量化可用于弹性知情决策的指标至关重要。考虑到地震波传播、液化和滑坡是影响分布式网络基础设施完整性的主要现象,建立了铁路系统地震多灾害风险和恢复评估的综合概率模型;这是通过基于gis的用户界面完成的。然后提出了一个说明性的案例研究,以评估伊朗德黑兰-萨里铁路的地震风险和恢复。实施结果表明,所提出的方法能够量化物理指标(包括网络组件的综合损坏状态、组件和系统级功能和恢复)和经济损失。这些指标可以帮助官员实施改造计划,以减少损失,提高铁路系统各部分的弹性。

ABSTRACT Hazard vulnerability is a characteristic of disaster risks from natural hazards, worsening climate challenges, complex geopolitical governance dynamics, and local development conditions. Comprehensive planning documents often articulate a community’s infrastructure strategies, policies, and capital improvement investments, and are pivotal for sustainable development of cities. This article introduces a new approach for an evidence-based enhanced preparatory technique for comprehensive plans, called Plan I.Q. The framework brings together two recent planning evaluation tools, which use a combination of qualitative assessment and spatial analysis in GIS to develop high-quality integrated plans. The case study presents results from applying the framework during the development of a new comprehensive plan for the City of Rockport in Texas, which incurred heavy damages from Hurricane Harvey in 2017. Results show improvements to plan quality and plan integration across the community’s network of plans, increasing the quantity and quality of infrastructure policies to reduce hazard vulnerabilities.
摘要灾害脆弱性是自然灾害、日益恶化的气候挑战、复杂的地缘政治治理动态和当地发展条件带来的灾害风险的特征。综合规划文件通常阐明了社区的基础设施战略、政策和资本改善投资,对城市的可持续发展至关重要。本文介绍了一种基于证据的综合规划强化准备技术的新方法,称为规划I.Q。该框架汇集了两种最新的规划评估工具,它们将GIS中的定性评估和空间分析相结合,以制定高质量的综合规划。该案例研究介绍了在为德克萨斯州罗克波特市制定新的综合计划期间应用该框架的结果,该市在2017年遭受了飓风哈维的严重破坏。结果显示,社区计划网络中的计划质量和计划集成有所提高,增加了基础设施政策的数量和质量,以减少危险脆弱性。

ABSTRACT The purpose of this research paper is to implement a machine learning model with the integration of the supply chain occupational reference (SCOR) model to develop an artificial intelligence-based system for resilient and sustainable supplier selection for a pharmaceutical company. Initially, the SCOR 4.0 model with the integration of Best Worst Method (BWM) has been used to develop the framework of customer satisfaction and to identify the critical elements of the suppliers. Later, the gradient boosting machine learning model has been implemented to classify the supplier as well as rank the suppliers from best to worst based on the acceptability score. The result shows that the gradient boosting algorithm performs well as a classifier, where the supplier with the most acceptability score represents the best supplier and the supplier with the least acceptability score represents the worst supplier. This study contributes to our understanding of how and when integrated SCOR and machine learning models can help improve supplier selection.
摘要本文的目的是实现一个集成供应链职业参考(SCOR)模型的机器学习模型,为制药公司开发一个基于人工智能的弹性和可持续供应商选择系统。最初,结合了最佳-最差方法(BWM)的SCOR 4.0模型已被用于开发客户满意度框架,并确定供应商的关键要素。随后,实现了梯度提升机器学习模型来对供应商进行分类,并根据可接受性得分从最佳到最差对供应商进行排名。结果表明,梯度提升算法作为分类器表现良好,其中可接受性得分最高的供应商代表最好的供应商,可接受性分数最低的供应商代表最差的供应商。这项研究有助于我们理解集成的SCOR和机器学习模型如何以及何时可以帮助改进供应商选择。

Initially, the SCOR 4.0 model with the integration of Best Worst Method (BWM) has been used to develop the framework of customer satisfaction and to identify the critical elements of the suppliers. Later, the gradient boosting machine learning model has been implemented to classify the supplier as well as rank the suppliers from best to worst based on the acceptability score. The result shows that the gradient boosting algorithm performs well as a classifier, where the supplier with the most acceptability score represents the best supplier and the supplier with the least acceptability score represents the worst supplier. This study contributes to our understanding of how and when integrated SCOR and machine learning models can help improve supplier selection.","PeriodicalId":45395,"journal":{"name":"Sustainable and Resilient Infrastructure","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2023-01-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43830350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Health & safety and economic prosperity of citizens are ensured with services provided by core public infrastructure (CPI). The CPI are subject to increased demand for service, deleterious reactions and impact due to climate change that accelerate their aging and deterioration. Canada’s first National Infrastructure Report Card (2012), for example, showed the Water System, Storm Drainage System, and Wastewater System are in ‘fair’ to ‘very poor’ conditions. The replacement costs of these assets, respectively, are $25.9, $15.8, and $39 billion (in 2010 dollars). With increased aging and deterioration, limited resource and customer expectations for minimum acceptable level of service, managing the assets is challenging. To better understand how to deal with these complexities, this Special issue brought invited papers from the experts in the domain. This special collection focused on the buried infrastructure distribution systems (Potable water assets, and Storm water and Wastewater assets). The present special issue is comprised of invited papers from leading researchers in the domain, and are discussed in the following order:
核心公共基础设施(CPI)提供的服务确保了公民的健康、安全和经济繁荣。CPI受到服务需求增加、有害反应和气候变化影响的影响,加速了其老化和恶化。例如,加拿大第一份国家基础设施成绩单(2012年)显示,供水系统、雨水排放系统和废水系统的状况从“尚可”到“极差”。这些资产的重置成本分别为259亿美元、158亿美元和390亿美元(以2010年美元计)。随着老化和恶化的加剧,资源和客户对最低可接受服务水平的期望有限,管理资产具有挑战性。为了更好地理解如何处理这些复杂性,本期特刊邀请了该领域专家的论文。本次特别收集的重点是埋地基础设施分配系统(饮用水资产、雨水和废水资产)。本特刊由该领域领先研究人员的受邀论文组成,按以下顺序进行讨论:
