Percolation-based health management of complex traffic systems

《工程管理前沿（英文）》 2021年第8卷第4期页码 557-571 doi: 10.1007/s42524-021-0174-0

摘要： System health management, which aims to ensure the safe and efficient operation of systems by reducing uncertain risks and cascading failures during their lifetime, is proposed for complex transportation systems and other critical infrastructures, especially under the background of the New Infrastructure Projects launched in China. Previous studies proposed numerous approaches to evaluate or improve traffic reliability or efficiency. Nevertheless, most existing studies neglected the core failure mechanism (i.e., spatio–temporal propagation of traffic congestion). In this article, we review existing studies on traffic reliability management and propose a health management framework covering the entire traffic congestion lifetime, from emergence, evolution to dissipation, based on the study of core failure modes with percolation theory. Aiming to be “reliable, invulnerable, resilient, potential, and active”, our proposed traffic health management framework includes modeling, evaluation, diagnosis, and improvement. Our proposed framework may shed light on traffic management for megacities and urban agglomerations around the world. This new approach may offer innovative insights for systems science and engineering in future intelligent infrastructure management.

Wei ZENG, Jinwen ZHANG, Hongwei WANG, Hongtao ZHOU

《工程管理前沿（英文）》 2018年第5卷第1期页码 88-97 doi: 10.15302/J-FEM-2018077

摘要： In this paper the Hong Kong-Zhuhai-Macao Bridge project is taken as a case to analyze supplier development in infrastructure mega-projects. Compared with manufacturing industry, the characteristics of supplier development in infrastructure mega-projects is analyzed in term of development motives, supplier selection, quality management, production mode, owner participation and risks. The critical factors influencing the construction supplier development are identified, which include incentives, collaboration, future market, trust and bilateral communication. Furthermore, focusing on the incentives for the supplier’s product quality and production capacity improvement, decision-making framework models are proposed to design the incentive mechanisms.

collaborative approach for urban underground space development toward sustainable development goals: Critical

Fang-Le PENG, Yong-Kang QIAO, Soheil SABRI, Behnam ATAZADEH, Abbas RAJABIFARD

《结构与土木工程前沿（英文）》 2021年第15卷第1期页码 20-45 doi: 10.1007/s11709-021-0716-x

摘要： The utilization of urban underground space (UUS) offers an effective solution to urban problems but may also negatively affect urban development. Therefore, UUS development needs better concerted guidelines to coordinate various urban systems and the multiple components of the underground world. Sustainable Development Goals (SDGs), which should be viewed as important yardsticks for UUS development, do not explicitly mention urban underground space, although many of them are affected by both the positive and negative consequences of its development. To fill this gap, this review lays the foundations of relevant UUS concepts and uses exemplary cases to reveal that 11 out of 17 SDGs can be linked with UUS uses. These linkages also manifest that land administration, integrated planning, architectural design, and construction technology are critical dimensions for increasing the contributions of UUS to the realization of SDGs. To achieve multi-disciplinary synergies among these four critical dimensions, a collaborative approach framework based on spatial data infrastructure is required. Thus, this work provides academics and practitioners with a holistic view of sustainable UUS development.

Steve Hsueh-Ming Wang

《工程管理前沿（英文）》 2016年第3卷第3期页码 239-245 doi: 10.15302/J-FEM-2016047

摘要： Management of the program quality for international infrastructure construction projects is complicated. Sustainability of these programs is the key for them to succeed in their lifecycles. This paper investigated current program quality management and compared it with the results of recent surveys of KGMP. A method for the sustainable program quality management of the international infrastructure construction management is proposed and demonstrated by research projects. The cycle of accountability, predictability, balance ability, and policy was proposed. The findings from the KGMP’s survey and this research show that the trend of the sustainable program quality management of the international infrastructure construction is transferring from agility to alacrity in the balancing of the metrics among economy, ecology, culture, and politics.

Yamuna KALUARACHCHI

《工程管理前沿（英文）》 2021年第8卷第1期页码 98-108 doi: 10.1007/s42524-020-0136-y

摘要： Cities are incorporating smart and green infrastructure components in their urban design policies, adapting existing and new infrastructure systems to integrate technological advances to mitigate extreme weather due to climate change. Research has illustrated that smart green infrastructure (SGI) provides not only climate change resilience but also many health and wellbeing benefits that improve the quality of life of citizens. With the growing demand for smart technology, a series of problems and challenges, including governance, privacy, and security, must be addressed. This paper explores the potential to transition from grey, green, or smart silos to work with nature-based solutions and smart technology to help change cities to achieve considerable environmental and socio-economic benefits. The concepts of grey, green, and smart infrastructure are presented, and the needs, benefits, and applications are investigated. Moreover, the advantages of using integrated smart, green nature-based solutions are discussed. A comprehensive literature review is undertaken with keyword searches, including journal papers, stakeholder and case study reports, and local authority action plans. The methodology adopts multimethod qualitative information review, including literature, case studies, expert interviews, and documentary analysis. Published data and information are analysed to capture the key concepts in implementing SGI systems, such as storm-water control, flood and coastal defense, urban waste management, transportation, recreation, and asset management. The paper investigates the elimination of silo approaches and the alleviation of the destructions caused by extreme weather events using these interdependent SGI systems supported by novel data-driven platforms to provide nature-based solutions to boost the health and wellbeing of the residents.

Silk Roads for the 21st Century: Engineering Mega-Infrastructure for Development and Sustainability

Tony Marjoram

《工程管理前沿（英文）》 2016年第3卷第3期页码 187-196 doi: 10.15302/J-FEM-2016038

摘要： Infrastructure facilitates the movement of people, the production and distribution of goods and services, and underpins development. Infrastructure is expensive and long-lasting, and needs long-term policy, planning and management, in terms of design, construction, operation and maintenance. Infrastructure relates particularly to engineering and technology. All technological change brings economic, social, cultural and environmental change, planned and unpredicted. Mega levels of technology bring mega levels of change, effects and impacts. Mega infrastructure such as the Silk Road Economic Belt and 21st Century Maritime Silk Road, the “One Belt, One Road” (OBOR) initiative, announced by President Xi Jinping in 2013, will require equally mega policy, planning and management. This paper will discuss policy, planning and management issues relating to mega infrastructure and the OBOR initiative, with particular reference to energy, communications, transportation, health, emergency preparedness and response, and less predictable areas of change, for example in disease prevention and control, within the overall need for economic, environmental and ecological sustainability. The paper will discuss associated needs for education, training and capacity building in engineering. The paper will also refer to lessons learnt from the original Silk Road in the context of the development of civilizations and intercultural dialogue through the transfer of goods, services, technologies, ideas, knowledge, customs, cultures and philosophies, less predictable and unwanted transfers, for example of disease, and the need for awareness, policy, planning and management of such wider issues.

Financing climate-resilient infrastructure: Determining risk, reward, and return on investment

Peter B. MEYER, Reimund SCHWARZE

《工程管理前沿（英文）》 2019年第6卷第1期页码 117-127 doi: 10.1007/s42524-019-0009-4

摘要：

Urban infrastructure investment is needed for both, mitigation of climate risks and improved urban resiliency. Financing them requires the translation of those benefits into measurable returns on investment in the context of emerging risks that capital markets can understand and appreciate. This paper develops a generic framework to identify what are the necessary and sufficient factors to economically favor climate-change resilient infrastructure in private investment decisions. We specifically demonstrate that carbon pricing alone will not generate the needed will, because market prices at present systematically fail to account for climate change risks such as the costs of stranded assets and the national and local co-benefits of investments in climate resiliency. Carbon pricing is necessary, but not sufficient for an enhanced private financing of climate-resilient infrastructure. The Paris Agreement and other supra-local policies and actors including city networks can concretely help to generate the sufficient social and political will for investments into climate change mitigation and resiliency at the city level.

Evaluation of the contract reliability for alternative infrastructure project delivery: a contract engineering

Bing WANG, Qingbin CUI, Shuibo ZHANG

《工程管理前沿（英文）》 2019年第6卷第2期页码 239-248 doi: 10.1007/s42524-019-0018-3

摘要： Governments at all levels are increasingly motivating the private sector to participate in infrastructure development using alternative project delivery methods to relieve financial burden. When designing contracts, governments usually offer incentives while requiring cost or time guarantee to balance project attractiveness to the private sector and fair protection of public interest. However, a practical and critical problem is how to properly design these provisions. Although previous studies have investigated the value of these provisions, a knowledge gap still exists with respect to methods of fairly and effectively designing such provisions. This study fills this gap by developing a methodology that analyzes the appropriateness of guarantee or warranty provisions for contracts. In this study, a contract reliability index is constructed, and a process of evaluating contract reliability is proposed. The New Mexico Highway 44 project, in which three warranty provision arrangements are investigated, is used as a case study to illustrate the analysis process. Results show that although a ceiling clause can effectively motivate the private sector to participate in the project, it sacrifices a significant amount of public benefits. By contrast, although a warranty option can protect public benefits, it cannot effectively incentivize the private sector. A combination of the ceiling clause and the warranty option will therefore result in improved contract provision design. The proposed methodology in this study is especially useful for governments in properly determining contract clauses in infrastructure development.
