“…In this study, the mean value µ, standard deviation σ, key index R, and discrete value δ were calculated, which reflected the average level, degree of variation, importance of each indicator, and the consistency of the respondents' opinions, respectively. Bajjou and Chafi [63] believed that the larger the σ, the greater the variation in the indicator score. The discrete value δ is the ratio of standard deviation to mean value.…”

The prefabricated building has been proven to be an effective approach for enhancing the sustainability of the construction industry. In recent years, the Chinese government has promulgated a series of policy documents to promote the advancement of prefabricated buildings. However, in practice, there are still numerous problems related to design, production, and construction, as well as the coordination between various stages. This study aimed to fill the gap in research regarding the application of EPC (Engineering–Procurement–Construction) in prefabricated buildings in China. As most of the risks of projects are borne by general contractors in the EPC mode, the risks faced by prefabricated building projects using EPC were systematically analyzed in this study from the perspective of general contractors. After learning about the risks of assembly construction in different countries, this study conducted a questionnaire survey to establish an evaluation system, and a comprehensive evaluation method was put forward to determine the weight of each indicator. Furthermore, an evaluation model based on grey–fuzzy theory was developed in this study, which was applied to a real project in Nanjing, China. The results indicated the applicability of the established evaluation system and model and determined the risk level of the project. Additionally, in this case study, it was found that construction and design were the major factors determining the risk level of the project. This study contributes to the body of knowledge regarding the integration of EPC in prefabricated buildings, which has practical application value for general contractors when conducting risk assessments.

“…This includes material-related waste, to which the word waste predominantly refers in construction, but also waste associated with inputs such as workforce, time and equipment (e.g., activity start delays, rework, unused employee creativity, long approval process, etc.) [90]. The core principles of lean thinking within the construction industry include waste reduction, process focus in production planning and control, end customer focus, continuous improvements, cooperative relationships and systems perspective [15].…”

The relevance of supply chain management (SCM) is being increasingly recognized in the construction industry. However, its implementation has been limited and is still challenging for researchers and practitioners. An adequate and systematic understanding of context-specific core concepts and practices are considered fundamental to foster its implementation. This paper aims to provide a holistic look into the existing research on elements underlying SCM in the construction industry. It adopts a systematic literature review method to examine almost two decades of publications and uses a comprehensive SCM framework to synthesize the findings. The results revealed a set of 19 core elements clustered in five subject areas (i.e., ‘strategic management’, ‘logistics’, ‘relationships’, ‘best practices’ and ‘organizational behavior’) that have a prominent role in construction SCM. Every core element was analyzed in detail and the results were discussed in the context of other evidence. This study produced the first comprehensive picture of the current state of knowledge, providing relevant contributions to enhance the understanding and implementation of SCM within the construction industry.

“…However, investigating practices alone does not guarantee lean performance improvement. The appraisal of waste is a favorable approach to enhance production system performance as it may specify possible areas of progress and sources of ineffectiveness (Bajjou and Chafi, 2019).…”

Purpose This study aims to propose a method for measuring lean supply chain management (LSCM) maturity based on the main lean practices and existing waste of a supply chain. Design/methodology/approach A three-stage approach was developed. First, a thorough literature review was performed to raise concepts and previous findings on maturity models (MMs) and LSCM. This review’s outcomes were then validated by experts in the field using the fuzzy Delphi method (FDM). Subsequently, the proposed model was illustrated and assessed based on a multi-case study. Findings All companies attained high outcomes in the elimination of the waste pillar. The pillars of logistics management, continuous improvement and information technology management also stood out in the three organizations’ results. The company with the lowest maturity level operates in a make-to-order production policy, which may harm the lean supply in its supply chain. Practical implications The proposed model can reveal external opportunities and threats and internal strengths and weaknesses in supply chains (SCs). It is also capable of providing a clear roadmap for SC improvement in companies. Originality/value To the best of the authors’ knowledge, no study to date has proposed a MM in the LSCM context using FDM and considering the crucial relationship between lean practices and wastes.
