“…That is, finding the best trade-off solutions for the project Chapter 2 -Literature review improvement, including the safety issues, should be indispensable, i.e., it is necessary to incorporate the MOO solving methods.

“…Tunnel-induced damage has become a major concern because potential damage could be caused by tunneling to the surrounding buildings and subsurface structures (Bilotta and Russo, 2011). The influence of the tunneling process on the surrounding buildings could be complicated, and it could be extremely difficult to precisely study the interaction because of the high uncertainty in the tunneling process, surrounding conditions, soilstructure interactions, and building material properties (Zhang et al, 2017d). A settlement risk caused by the tunneling process is presented in Fig.…”

“…Though 16 variables in total are identified, only a few variables may be able to be adjusted in practice. Among those 16 variables, x11, x9, and x16 are identified as the three most significant variables influencing tunnel-induced damages (Zhang et al, 2017d).…”

“…However, because of the high complexity and uncertainty, tunnel-induced damages could be very complicated and very difficult to be rigorously analyzed (Zhang et al, 2019). To investigate the tunnel-induced damages, quite a number of variables and constraints could be involved, and many of them are very difficult to be measured because of the complexity (Zhang et al, 2017d). This means that it would be difficult to apply the analytical and numerical models without accurately identifying the causal relationships between inputs and outputs in complex projects, such as the tunnel-induced damage mitigation problem.…”

“…However, different objectives and criteria are identified that are closely related to the management of tunnel-induced damages. For example, three objectives, minimizing the accumulative settlement, daily settlement, and building title rate, were identified in the study of Zhang et al (2017d) for the analysis of tunnel-induced damage to the adjacent buildings. It was found that controlling these three objectives within their respective standards (30 mm, 2 mm/day, and 3.0‰ for the accumulative settlement, daily settlement and building tilt rate, respectively) was critical to reduce the tunnelinduced damage to the adjacent buildings (2011).…”

I have to say deepest gratitude only goes to my supervisor Prof. Zhang Limao for his sincere guidance and kind support throughout the research. After the completion of my undergraduate study, I had worked for several years, and I lost. I lost my motivation and didn't know what should I do next. I had tried part-time jobs for years, and out of those experiences, I thought being a teacher may be the right thing for me. I believed I was good at learning and I loved sharing my knowledge and communicating with others.That's why I decided to get back to school, pursuing a doctoral degree so that I could be a teacher one day. To be honest, however, I was not that confident. It took courage for me to make this decision, and I would try my best without doubt, but I also acknowledge that I had left school for too many years, and I wasn't very sure if I could catch up and become a qualified doctoral candidate in time. So, firstly, I have to thank prof. Zhang for giving me the opportunity to be a doctoral student here. Secondly, it was his demanding and supportive supervision that really changed me. I had to admit that I was kind of stressed at the beginning, for that I was way behind from the schedule. I had too much to learn, and it was my own responsibility to catch up in time. However, prof. Zhang tutored me with unbelievable patience. I cannot even remember how many times and how much time prof. Zhang had spent to teaching me even if I made the stupidest mistakes. I just know that I may achieve nothing if without his great patience and valuable, inspiring, and professional tutorial. What's more, he sets an example of being a good supervisor for me. He not only helps me become a qualified doctoral student, but also his professionalism, dedication, and meticulous attitude enlighten me of what a great supervisor is and make me determined to be one as he does. Now, I know how, I am confident and I am resolved that I will become a qualified professor.Surely, I am also deeply grateful to my family, my parents and my beloved sister.You are always there to support. Thank you.

Decision-making is critical to the success of safety management in construction projects. Due to the simultaneous evaluation of numerous criteria and objectives, multiple criteria decision making (MCDM) is essential for decision problem-solving. Several MCDM methods are continuously being developed and are progressively used to solve real-world construction safety challenges. This study aimed to understand the progress of the MCDM methods and their application in construction safety. A total of 52 articles were found after conducting a systematic literature review (SLR) using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) review method. The research trend is then described using bibliometric analysis in terms of the number of publications per year, sources of documents, influential authors and countries, highly cited articles, and research areas. The findings indicated that AHP (analytic hierarchy process), and its fuzzy version, FAHP, were applied mainly in construction safety research. The key areas where MCDM methods were focused on are safety risk assessment, safety culture, and safety programs. The study findings are expected to assist construction practitioners by allowing them to use the best and optimal MCDM method for problem-solving related to safety.

Selecting Appropriate Risk Response Strategies Considering Utility Function and Budget Constraints: A Case Study of a Construction Company in Iran

et al. 2022

Successful implementation of construction projects worldwide calls for a set of effective risk management plans in which uncertainties associated with risks and effective response strategies are addressed meticulously. Thus, this study aims to provide an optimization approach with which risk response strategies that maximize the utility function are selected. This selection is by opting for the most appropriate strategies with the highest impact on the project regarding the weight of each risk and budget constraints. Moreover, the risk assessment and response strategy of a construction project in Iran as a case study, based on the global standard of the project management body of knowledge (PMBOK) and related literature, is evaluated. To handle the complexity of the proposed model, different state of the art metaheuristic algorithms including the ant lion optimizer (ALO), dragonfly algorithm (DA), grasshopper optimization algorithm (GOA), Harris hawks optimization (HHO), moth-flame optimization algorithm (MFO), multi-verse optimizer (MVO), sine cosine algorithm (SCA), salp swarm algorithm (SSA), whale optimization algorithm (WOA), and grey wolf optimizer (GWO). These algorithms are validated by the exact solver from CPLEX software and compare with each other. One finding from this comparison is the high performance of MFO and HHO algorithms. Based on some sensitivity analyses, an extensive discussion is provided to suggest managerial insights for real-world construction projects.
