“…Factors. Most scholars used DEMATEL model for research [37][38][39][40][41][42], and some experts and scholars also combined two or more mathematical models based on previous studies, such as AHP-DEMATEL model [43], Fuzzy-DEMATEL model [44,45], Grey-DEMATEL model [46,47], DEMA-TEL-ANP model [48], COWA-DEMATEL model [49], DEMATEL-TOPSIS model [50], DEMATEL-COPRAS model [51], DEMATEL-ISM model [52][53][54][55], and DEMA-TEL-ISM-MICMAC model [56]. To a certain extent, they have enriched the theoretical and practical research on the identification methods of key influential factors.…”

With the global resource and environment problems becoming increasingly prominent and the government procurement scale growing rapidly, the implementation of green procurement for government public project will have a significant impact on the protection of resources and environment. Identifying the key influential factors of bid evaluation in government public project green procurement is of great significance for promoting the construction of government public project green procurement system. Based on the Decision-Making Trial and Evaluation Laboratory (DEMATEL) method, Back Propagation (BP) neural network is introduced to determine the direct-relation matrix, optimizing the traditional DEMATEL method. This paper uses the BP-DEMATEL model to identify key influential factors of bid evaluation in government public project green procurement by algorithmic design. Among 56 indicators, which have formed a set of index system of bid evaluation in government public project green procurement, 20 key influential factors are identified, providing reference for the government to implement green procurement in the field of public project. The research results not only enrich and improve the theoretical and practical research in the field of government public project green procurement, but also solve the defects of traditional DEMATEL method that the method is too subjective and tedious when obtaining the influence degree between each pair of factors to construct direct-relation matrix through questionnaire surveys or expert scoring method, thus expanding the scope of the application of the DEMATEL method.

“…Professor Warfield (1974) firstly proposed ISM to analyze the hierarchical structure of complex systems by combing graph theory and Boolean algebra. ISM enables complex systems within multivariable elements and vague structures to be visualized in hierarchical structures and explained by multilevel of influence paths (Lin et al, 2021). The process of structuring the elements in terms of the issue is realized by mathematical computer tools and helps to show how the elements interrelate with each other during the system.…”

PurposeRisk factors related delay hinder the schedule performance of most construction projects in the world. It is a critical challenge to realize the advantages of prefabricated construction projects (PCPs) under the negative effect of schedule delay. This paper aims to propose an exhaustive list of risk factors impeding the progress of PCPs and evaluate the collected risk factors based on the cause–effect relations. The ultimate goal is to improve the understanding of the complex relations among various risk factors related delay in PCPs, and also offer managers a reference on aspect of schedule risk management.Design/methodology/approachThis paper proposes a hybrid method of GT–DEMATEL–ISM, that is combing grounded theory, DEMATEL (decision-making trial and evaluation laboratory) and ISM (Interpretative Structural Modeling), to collect, evaluate and structure risk factors related delay for PCPs. The research procedure of this methodology is divided into three stages systematically involving qualitative and quantitative analysis. In the first stage, GT is utilized to implement qualitative analysis to collect the risk factors leading to schedule delay in PCPs. While, the quantitative analysis is to analyze and evaluate the collected risk factors based on the cause–effect relations in the next two stages evaluation by the DEMATEL focuses on quantifying the priority and intensity of the relations between factors. Additionally, ISM is employed to construct the hierarchical structure and graphically represent the pairwise relations between factors.FindingsThe outcome of qualitative investigation by grounded theory proposes a theoretical framework of risk factors related delay for PCPs. The framework contains three levels of category, namely, core category, main category and initial category and provides a list of risk factors related delay. Following this finding, evaluation results by the DEMATEL classify factors into cause and effect groups and determine 11 critical delay risk factors. Meanwhile, the findings show that risks referring to organizational management issue foremost impact the progress of PCPs. Furthermore, a systemic multilevel hierarchical structure model is visually constructed by ISM to present the pairwise linkages of critical factors. The model provides the risk transmission chains to map the spread path of delay impact in the system.Originality/valueThe contribution of the study involves twofold issues. Methodologically, this research proposes a hybrid method GT–DEMATEL–ISM used to identify and analyze factors for a complex system. It is also applicable to other fields facing similar problems that require collecting, evaluating and structuring certain elements as a whole in a comprehensive perspective. The theoretical contribution is to fill the relevant research gap of the existing body of knowledge. To the best knowledge of the authors, this paper is the first attempt to integrate qualitative and quantitative research for risk analysis related delay and take the insight into the whole process of PCPs covering off-site manufacture and on-site construction. Furthermore, the analysis of findings provided both a micro view focusing on individual risk factor and a managerial view from a systematic level. The findings also contribute the effective information to improve the risk management related schedule delay in PCPs.

“…The incredible rise of the expansion of high-speed rail, lower tracking intervals, a more complex operating environment, and shorter departure times are all results of larger train fleet sizes and shorter departure times. (Shangguan, 2022;Lin, 2021) So it is crucial to improve the general level of safety in the railway setting. Train operation and the issue of train combinations on station platforms are two of the fundamental scheduling issues for railway safety: this aspect increases the complexity of train traffic problems, particularly in high-speed stations.…”

Rail transport has been changing the mobility of people. The Railway's development has pointed the focus on the safety management of trains and infrastructure, particularly related to passengers. This paper focuses on the methods adopted to guarantee high safety in railways; for this reason, it was interesting to present a literature analysis about this topic. The authors short-listed 48 articles for indepth analysis. Bibliometric research and a thorough literature assessment were conducted to evaluate the safety management in the Railway area. Today, the attention of experts and railway managers is very high on high-speed railways because of their high-risk levels. For this reason, many advanced technologies have been developing all over the World, thanks to the new artificial intelligence tools and machine learning, to guarantee a constantly high degree of safety. Especially the stations and specifically, the platform zones, are crucial hotspots for railway accidents, particularly suicide events. Some prevention techniques showed an increment in safety quality and made Railway the safest transport infrastructure. So, a resilient model applied to safety railways could improve even more substantial safety degree.
