Strategic Project Management to Use the Grand Challenge Scholars Program to Address Urban Infrastructure

David A. Wyrick,Warren Myers

《工程管理前沿（英文）》 2016年 第3卷 第3期   页码 203-205 doi: 10.15302/J-FEM-2016046

摘要： Throughout the world, infrastructure to support cities is critical to support sustainable and responsible economic development. This can include new infrastructure projects in the case of growing areas. It can also include the renewal and upgrading of existing infrastructure in areas that have been inhabited and already developed. Infrastructure includes roads, bridges and transportation systems; power grids and energy service; internet and telecommunications; and water and sewer services. This development can be part of a system of systems, in which government, industries, and universities can contribute knowledge, skills, and abilities. This paper will investigate the strategic project management taken by one university to provide an academic experience that will prepare engineering students to address several of the Grand Engineering Challenges of the 21st Century, as identified by the US National Academy of Engineering. The challenges relating to energy, water, information, and urban infrastructure can be approached using the functions of teaching, research, and service. By approaching the challenges strategically, resources of faculty time, student effort and laboratory facilities can be leveraged to achieve greater results. This case study will describe the efforts and results to date and identify opportunities for future growth.

Optimizing nitrogen management in the food system for sustainable development: a case study of Quzhou REVIEW

《农业科学与工程前沿（英文）》 2024年 第11卷 第1期   页码 113-121 doi: 10.15302/J-FASE-2024540

摘要：

Nitrogen (N) is an essential nutrient for food production. The rapid increase in population requires high inputs of N to meet the growing food demand. If not managed well, the substantial loss of N from the food system has multiple impacts on grain yield, air and water pollution, and the economic benefits of agricultural. Multi-objective (food security, environmental sustainability and economic sustainability) synergistic consideration of N management in the food system is still lacking. This study employed strategies for optimizing N management in the food system, using Quzhou County as a typical example on the North China Plain. Firstly, a food chain approach was adopted to understand drivers and reasons behind N losses from the food system. Secondly, a top-down approach was used to define multi-objective N management, taking into consideration food security, environmental sustainability and economic sustainability. Multi-objective N management aims to reduce N losses to the environment and increase N use efficiencies, while simultaneously increasing yields and economic benefits. Thirdly, 3R (reduce-retain-recycle) N management strategies were identified for specific crops and animals through a bottom-up approach and then analyzed the potential of these strategies to achieve the multi-objectives. Finally, there is a discussion of how to engage different stakeholders to promote the technologies implementation. This study provides new insights into the synergistic achievement of multi-objective N management in the food system and the development of environmentally-friendly agriculture.

Organizational evolution of project management teams over the whole lifecycle of megaprojects: Case study

《工程管理前沿（英文）》 2023年 第10卷 第3期   页码 439-454 doi: 10.1007/s42524-022-0211-7

摘要： Project management teams are critical in the implementation of megaprojects, but their evolution throughout the project lifecycle has not been clearly explained. This paper explores the organizational evolution of megaproject management teams through a longitudinal retrospective case study of the Hong Kong–Zhuhai–Macao Bridge (HZMB) project. The organizational evolution is examined in terms of management objectives, management content, and organizational structure. The organizational evolution of the HZMB project management team exhibits stage differentiation with the coexistence of turbulence and stability. Changes in the external environment are the driving force for organizational evolution, whereas a flexible organizational strategy is critical in promoting this evolution. Basing on the HZMB case study, this paper summarizes six critical measures that facilitate the organizational evolution of megaproject management teams. Our findings add value to megaproject management theory and provide a better understanding of the dynamics and complexity of megaproject organizational management.

Water environmental planning and management at the watershed scale: A case study of Lake Qilu, China

HUANG Kai, GUO Huaicheng, LIU Yong, ZHOU Feng, YU Yajuan, WANG Zhen

《环境科学与工程前沿（英文）》 2008年 第2卷 第2期   页码 157-162 doi: 10.1007/s11783-008-0011-2

摘要： Water environmental planning and management has become essential for guiding the water pollution control activities. Past water pollution control activities have been site specific, with little thought on water quality standard reaching at the watershed scale. Based on the watershed approach, a seven-step methodological framework for water environmental planning and management was developed. The framework was applied to water environmental planning and management of the Lake Qilu watershed in Yunnan Province, China. Results show that the reduction amount of total nitrogen (TN) under the plan is 1,205 tons per year so that the target of environmental capacity can be reached in 2020. Compared with traditional methods, the framework has its prevalence and could be generalized to analogous watersheds.

Identifying critical factors that affect the application of information technology in construction management: A case study of China

Meishan JIA, Youquan XU, Pengwang HE, Lingmin ZHAO

《工程管理前沿（英文）》 2022年 第9卷 第2期   页码 281-296 doi: 10.1007/s42524-020-0122-4

摘要： The new mode for managing construction projects with information technology (IT) has attracted worldwide attention because it can help managers and workers perform tasks and bring potential benefits, such as high-quality products and accident-free production, effectively. However, the application of IT in site have not achieved expected results because it is faced with many constraints caused by internal factors from enterprises and projects and external factors from the government and environment. Although many relevant studies have discussed the constraints of implementing different IT and devices in the construction industry or site, few articles have specifically focused on identifying and analyzing the indicator system. In this work, we took China as the background, scientifically identified 23 influential factors that affect the implementation of IT in construction management through literature review and expert interviews. Subsequently, questionnaires were issued, and Delphi method was used to obtain empirical data that aimed at four different management fields. Then, an efficient and convenient method called DEMATEL was used to deal with these data. Afterward, the factors were divided into four categories, namely, core, diving, independent, and impact factors. Finally, the similarities and differences of the analysis results from the four fields were compared, and the key factors were identified. Results show that the cross-domain talent ability, concept and value cognition, and organization structure are core factors in all management fields that should be managed first along with the IT innovation ability in the enterprise. The formulation of technical standards and related device and training input are also critical in specific fields. Strategic planning plays a role in macro control and promotion. Data management and application, platform construction, solution, and collaboration have direct impacts on information management. The research results provide suggestions not only for the government to formulate effective policies for IT application and promotion in construction industry, but also for enterprises to take measures in improving management efficiency in the construction site and realizing its substantial benefits.

Toward to agricultural green development by multi-objective zoning and nitrogen nutrient management:a case study in the Baiyangdian Basin, China RESEARCH ARTICLE

《农业科学与工程前沿（英文）》 2024年 第11卷 第1期   页码 140-154 doi: 10.15302/J-FASE-2023533

摘要：

Although China has achieved great advancements toward national food security, the country is still confronted with a range of challenges, including natural resource stress, imbalanced diets and environmental pollution. Optimized management of crop–livestock systems is the key measure to realize agricultural green transformation. However, optimized management of crop–livestock systems that use multi-objective zoning is lacking. This study employed a multi-objective zoning management approach to comprehensively analyze four indicators: ammonia volatilization, nitrogen surplus, soil carrying capacity and ecological red line area. With its significant ecological integrity and a strong emphasis on sustainability, the Baiyangdian Basin serves as a unique and suitable test case for conducting analyses on multi-objective nutrient optimization management, with the aim to facilitate the agricultural green transformation. This study finds that less than 8% of the area in the Baiyangdian Basin meet the acceptable environmental indicator standard, whereas around 50% of the area that had both nitrogen surplus and ammonia volatilization exceeded the threshold. Implementation of unified management, that is, the same management technique across the study areas, could result in an increase of areas meeting environmental indicator thresholds to 21.1%. This project developed a novel multi-indicator partition optimization method, in which distinct measures are tailored for different areas to satisfy multiple environmental indicators. Implementation of this method, could potentially bring more than 50% area below the threshold, and areas with ammonia emissions and nitrogen surplus could be reduced to 15.8%. The multi-indicators partition optimization method represents a more advanced and efficiency-oriented management approach when compared to unified management. This approach could be regarded as the best available option to help China achieve agricultural transformation to improve efficient production and reduce environmental pollution. It is recommended that current policies aimed at nutrient management toward sustainable agricultural development should shift toward the application of multi-indicators partition optimization.

An interval joint-probabilistic programming method for solid waste management: a case study for the city

Yi XU, Shunze WU, Hongkuan ZANG, Guiguang HOU

《环境科学与工程前沿（英文）》 2014年 第8卷 第2期   页码 239-255 doi: 10.1007/s11783-013-0536-x

摘要： Currently, environmental protection and resources conservation continue to be challenges faced by solid-waste managers in China. These challenges are being further compounded by rapid socioeconomic development and population growth associated with increased waste generation rates and decreased waste disposal capacities. In response to these challenges, an interval joint-probabilistic mixed-integer programming (IJMP) method is developed for supporting long-term planning of waste management activities in the city of Tianjin, which is one of the largest municipalities in the northern part of China. In the IJMP, joint probabilistic constraints are introduced into an interval-parameter mixed-integer programming framework, such that uncertainties presented in terms of interval values and random variables can be reflected. Moreover, a number of violation levels for the waste-management-capacity constraints are examined, which can facilitate in-depth analyses of tradeoffs among economic objective and system-failure risk. The results indicate that reasonable solutions have been generated. They are valuable for supporting the adjustment of the city’s existing waste-management practices and the long-term planning of the city’s waste-management facilities.

Ji-liang Zheng,Jun Hu,Xuan Zhou,Ching Yuen Luk

《工程管理前沿（英文）》 2015年 第2卷 第3期   页码 311-319 doi: 10.15302/J-FEM-2015045

摘要： Following rapid infrastructure development and industrialization, the problems of water pollution and water shortage have become more severe. Whether there is safe drinking water in cities has attracted wide attention. The ecological risk management of drinking water project is an important means of ensuring the safety of a drinking water source. Based on ecological risk assessment and management theories, this paper establishes an ecological risk management model and assessment system with the aim of providing theoretical guidance and scientific basis for formulating a policy on the safety and protection of drinking water sources in a city. Kunming is one of the cities plagued by severe water shortage in China. Its ecological risk management of drinking water has attracted the attention of both the local government and the public. Using Kunming as the case study, this paper conducts a comparative analysis and assessment on three major reservoirs that face ecological risks. It highlights the existing problems and gives helpful suggestions.

Classification and quantification of excavated soil and construction sludge: A case study in Wenzhou,

《结构与土木工程前沿（英文）》 2022年 第16卷 第2期   页码 202-213 doi: 10.1007/s11709-021-0795-8

摘要： With rapid urbanization in China, a large amount of excavated soil and construction sludge is being generated from geotechnical and underground engineering. For sustainable management of these construction wastes, it is essential to quantify their production first. The present study has attempted to classify the excavated soil and construction sludge according to their composition and geotechnical properties (particle size, water content, plasticity index). Based on these classifications, a new approach was proposed to quantify the production. The said approach was based on multi-source information, such as the urban topographic map, geological survey reports, urban master plan, and remote sensing images. A case study in Wenzhou city of China was also pursued to illustrate the validity of the newly developed approach. The research showed that in 2021–2025, the total excavated soils and construction sludge production in Wenzhou would reach 107.5 × 106 and 81.7 × 106 m3, respectively. Furthermore, the excavated soil was classified into the miscellaneous fill, crust clay, muddy clay and mud with silty sand. Likewise, the construction sludge was classified as liquid sludge and paste-like sludge. The classification and quantification can serve as guidance for disposal and recycling, thereby leading to high-level management of waste disposal.

Meta-synthesis management framework of a complex project: A case study of the deck pavement project of

Qiang MAI, Xing-lin GAO, Shi AN, Ding LIU, Ming LIU

《工程管理前沿（英文）》 2018年 第5卷 第1期   页码 4-16 doi: 10.15302/J-FEM-2018076

摘要： Innovative technology and deep uncertainty during the design and construction process of complex projects introduce great challenges to their organization and management. The traditional methods, represented in the project management body of knowledge (PMBOK) guide, can solve systematic problems; however, they cannot solve complex problems. Based on the management practice implemented in the deck pavement project of the Hong Kong-Zhuhai-Macao Bridge (HZMB), in this work, we propose a meta-synthesis management framework for a complex project from the perspective of the science of complexity. The method deems that the complexity of the project has the characteristic of being multi-scale both in the design phase and the construction phase. These problems can be classified into different categories, each of which requires a different strategy. As a result, it is first necessary to adopt the “exploration” strategy to reduce project complexity and to transform the deep uncertainty problems into systematic problems. Then, the “exploitation” strategy should be used to apply the PMBOK and other traditional methods to achieve the design and construction goals of the project and to improve its efficiency. More specifically, in the design phase of a complex project, the “innovative integration” process is used for the exploration of the new engineering technology and knowledge; then, the “functional integration” process is employed to define the system architecture, the interface relationship, the technical index, and other functions. In the construction phase, the “adaptive integration” process is used for the construction of the engineering organization system; next, the “efficient integration” process is employed to improve the actual construction performance. The meta-synthesis management framework proposed in this work reveals the multi-scale principle of solving complex problems in the management practice of a complex project, and develops the methodology of meta-synthesis.

摘要： This paper, proceeding from the project construction process, the management mode and the implementation way, makes an in-depth study of the environmental characteristics and the managerial elements of petrochemical engineering construction project, revealing the inherent laws, establishing a theoretical model, and proposing a theory of the mechanisms of construction project management; and presents profound revelations found for construction project management in petrochemical engineering in seven aspects, which can play a guiding role in improving the managerial performance of petrochemical construction project. The theory established proposes that: The construction project management in petrochemical engineering is a complex systematic process, formed of 5 phases and 55 sub-processes of management, and exposed to many factors of influence; the environmental characteristics and managerial elements exercise positive impacts on managerial performance, but different factors have different impacts and act in different ways on managerial performance; the managerial elements of petrochemical engineering construction project are tiered, transferable, systematic and quantifiable, and the role of managerial elements in the managerial performance can be systematically integrated, quantitatively explained and transferred in a multi-level way.

Effects of riparian vegetation patterns on the distribution and potential loss of soil nutrients: a casestudy of the Wenyu River in Beijing

Erhui GUO,Liding CHEN,Ranhao SUN,Zhaoming WANG

《环境科学与工程前沿（英文）》 2015年 第9卷 第2期   页码 279-287 doi: 10.1007/s11783-014-0667-8

摘要： A riparian ecosystem is an ecological transition zone between a river channel and terrestrial ecosystems. Riparian ecosystems play a vital role in maintaining stream health and bank stabilization. The types of riparian vegetation have changed greatly because of human activities along the Wenyu River. This study examines the impact of riparian vegetation patterns on water pollution due to soil nutrient loss. Four riparian vegetation patterns from the river channel to the upland were chosen as the focus of this study: grassland, cropland, grassland-cropland, and grassland-manmade lawn. The different distributions of soil nutrients along vegetation patterns and the potential risk of nutrient loss were observed and compared. The results showed that riparian cropland has the lowest value of total nitrogen (TN), total phosphorus (TP), available nitrogen (AN), available phosphorus (AP), and organic matter (OM), but it has the highest soil bulk density (BD). The distributions of soil TN, TP, AN, AP, and OM exhibited a declining trend from the upland toward the river channel for riparian cropland, whereas a different trend was observed for the riparian grassland. The vegetation patterns of grassland-cropland and grassland-manmade lawn show that the grassland in the lower slope has more nutrients and OM but lower soil BD than the cropland or manmade lawn in the upper slope. So, the lower-slope grassland may intercept and infiltrate surface runoff from the upland. The lower-slope grassland has higher levels of soil TN, TP, AN, and AP, and thus it may become a new source of nutrient loss. Our results suggest that the management of the riparian vegetation should be improved, particularly in densely populated areas, to control soil erosion and river pollution.

Hongtao ZHOU, Hongwei WANG, Wei ZENG

《工程管理前沿（英文）》 2018年 第5卷 第1期   页码 78-87 doi: 10.15302/J-FEM-2018075

摘要： The construction sites of mega construction projects (MCP) often have numerous participants with interfacing work within a highly complex system. It is critical how to realize collaborative work and information sharing among such participants. The information and communication technologies (ICTs) provides a technical guarantee for solving this problem. Existing research has been achieved the partial processes digitization of construction site, but certain problems still exist: 1)information perception of the construction site is passive. 2) common collaboration and coordination problems in the construction industry have not been addressed. The emerging trends of ICTs have resulted in the integration of various computer technologies such as CPS, BIM, big data, and cloud computing into construction process, which would changes behavioral and management mode of construction sites. These new ICTs have been applied successfully in MCP, in particular, Hong Kong-Zhuhai-Macao Bridge project. A new management mode of construction sites is inspired by these case. In this paper, a new management mode of construction site for MCP has been proposed, namely, smart construction site. The ultimate goal of smart construction site is to accomplish safe, efficient and high-quality construction. This study put forward the conceptual framework for smart construction site, and have identified three key elements of smart construction site, including information support platform, collaboration work, and intelligent construction management. A case study on Hong Kong-Zhuhai-Macao Bridge project work as an evidence to support the practicability of the proposed mode. Significant contributions of this study is to propose a new management mode for MCP in construction industry, which would enrich the body of knowledge or the construction management community. Future research should be dedicated to further explore the potential of smart construction site in MCP management.

《能源前沿（英文）》 2018年 第12卷 第3期   页码 411-425 doi: 10.1007/s11708-018-0577-8

摘要：

District heating systems using cogeneration technology and renewable resources are considered as an effective approach to resources conservation and reduction of greenhouse gas (GHG) emissions. However, wide-spread aging and depopulation problems, as well as the popularization of energy-saving technologies in buildings, are estimated to greatly decrease energy consumption, leading to inefficiency in district heating and barriers to technology proliferation. From a long-term perspective, land use changes, especially the progression of compact city plans, have the potential to offset the decrement in energy consumption that maintains the efficiency of district heating systems. An integrated model is developed in this paper based on building cohort analysis to evaluate the economic feasibility and environmental impact of introducing district heating systems to a long-term compact city plan. As applied to a case in the Soma Region of Fukushima, Japan, potential migration from the suburbs to the central station districts is simulated, where district heating based on gas-fired cogeneration is expected to be introduced. The results indicate that guided migration to produce concentrated centers of population can substantially increase the heat demand density, which supports a wider application of district heating systems and better low-carbon performance. These results are further discussed in relation to technology innovation and related policies. It is concluded that policies related to urban land use planning and energy management should be integrated and quantitatively evaluated over the long-term with the aim of supporting urban low-carbon sustainable development.
