TL;DR: This review formulates a clear picture of the current practice of these digital technologies and summarizes the main area of application and limitations of each technology when utilized in OSC.
Abstract: Off-site construction (OSC) is known as an efficient construction method that could save time and cost, reduce waste of resources, and improve the overall productivity of projects. Coupled with digital technologies associated with the Industry 4.0 concept, OSC can offer a higher rate of productivity and safety. While there is a rich literature focusing on both OSC and Industry 4.0, the implementation of associated digital technologies in the OSC context has not been fully evaluated. This paper intends to evaluate the current literature of digital technology applications in OSC. Scientometric analyses and a systematic review were carried out evaluating fifteen typical digital technologies adopted by OSC projects, including building information modelling (BIM), radio frequency identification devices (RFID), global positioning systems (GPS), the Internet of Things (IoT), geographic information systems (GIS), sensors, augmented reality (AR), virtual reality (VR), photogrammetry, laser scanning, artificial intelligence (AI), 3D printing, robotics, big data, and blockchain. This review formulates a clear picture of the current practice of these digital technologies and summarizes the main area of application and limitations of each technology when utilized in OSC. The review also points out their potential and how they can be better adopted to improve OSC practice in the future.

TL;DR: In this article, a prediction model was established by system dynamics, including direct CECI, indirect and operational CECIs, to accurately predict the peak of the peak carbon emission of the construction industry in China.
Abstract: China has become the world's largest carbon emitter, and its commitment to peak carbon emissions by 2030 is important for global development. The construction industry is one of China's biggest carbon emitters, and its peak has a direct impact on China's carbon commitment. Due to the regional heterogeneity of different provinces, the carbon emission of construction industry (CECI) at provincial level is of unique significance. To accurately predict the peak of provincial CECI, a prediction model was established by system dynamics, including direct CECI, indirect CECI and operational CECI. Taking Jiangsu province as an example, the single and multiple scenario settings with increasing R&D investment, promoting energy-saving buildings and implementing carbon trading from 2016 to 2030 was carried out, indicating that: 1) Without any carbon emission reduction measures, the CECI would maintain an annual growth rate of 5.58% to reach 530.61 million tons by 2030, and the indirect and operational CECI account for the majority of total with an average annual growth rate of 8.02% and 2.79% respectively. 2) All three measures had good carbon reduction effects, which would reduce the total CECI by 26.46% 21.68% and 10.68% respectively by 2030, but only when implemented simultaneously can CECI peak before 2030, 308.77 million tons at 2029. In the end, three policy implications was put forward. The framework presented in this paper provided a basis for the prediction of peak CECI in a province or state, which can help policy makers plan a more reasonable low-carbon development roadmap.

TL;DR: In this article, an interpretive structural model (ISM) is developed to show the inter-relationship of different criteria and their levels of importance in the vendor selection process, revealing that attitude and willingness for business and after sales service are as important factors as quality, delivery and practice.
Abstract: Vendor selection is one of the most important activities of a purchasing department. Traditionally, vendors are selected for their ability to meet the quality requirement, delivery performance and the price offered. However, as they are selected not only to meet the immediate requirement but also future needs, one needs to consider many other factors when selecting a reliable vendor. Analyses some of the most important criteria which have been classified into four categories: autonomous, dependent, linkage and driver depending on their driver power and dependence. Develops an interpretive structural model (ISM) to show the inter‐relationship of different criteria and their levels of importance in the vendor selection process. Reveals that “attitude and willingness for business” and “after sales service” are as important factors as quality, delivery and practice. These criteria are dependent on all the others. This analysis could provide a meaningful analytical base in the vendor selection process.

TL;DR: A weighting matrix applied to the elements of a maximal cycle set permits a set of digraphs to be developed, which allows for more detailed interpretation of a cycle.
Abstract: The interpretation of complex structural models is facilitated by a variety of operations that can be carried out by a computer. Several of these involve partitions on a reachability matrix, which describes a contextual relation among the elements of the system under study. When partitioning of the reachability matrix in various ways does not permit adequate interpretation, cycles are usually the source of difficulty. A weighting matrix applied to the elements of a maximal cycle set permits a set of digraphs to be developed, which allows for more detailed interpretation of a cycle. When still further development is needed, the maximal cycle sets can be identified and placed in a hierarchy based on an inclusion relation. This hierarchy suggests a natural order of study of the system proceeding from the least complex maximal cycle sets to the most complex sets.

TL;DR: In this article, the authors present the results of an interview survey of major construction clients about their expectations from and drivers for pre-assembly on their projects and identify time, cost, quality and productivity benefits through minimization of on-site operations and duration, less congestion on site, improved health and safety along with greater and more predictable quality.
Abstract: Pre-assembly is an important facet of the strategy to re-engineer construction. It can be categorized as: modular building; volumetric pre-assembly, non-volumetric pre-assembly and component manufacture/subassembly. This paper presents the results of an interview survey of major construction clients about their expectations from and drivers for pre-assembly on their projects. In particular, time, cost, quality and productivity benefits through minimization of on-site operations and duration, less congestion on site, improved health and safety along with greater and more predictable quality are identified. To get the best out of pre-assembly, clients acknowledge that they must be able to freeze the design early, provide reasonable lead times and provide time for presite prototyping. Clients' past experience has been mixed, with some citing tangible benefits, but others experiencing poor-quality products and a limited and disjointed supply chain - these mitigate against efforts to increase pre-assembly as p...
