Due to more complex structure and increasing prefabrication rate of precast concrete buildings, the assembly order between their constituent components is getting attention. In solve sequence planning optimization (ASPO) problem in Building Information Modelling (BIM) Improved Genetic Algorithm (IGA) are organically combined propose a new method called BIM-IGA-based ASPO method. This uses BIM for parametric modelling, IGA search an optimal sequence, then again visual simulation further test...

Good cooperation mechanism is an important guarantee for the advancement of industrialization construction. To strengthen partnership between producers, we analyze behavior evolution trend both parties using evolutionary game theory. Based on original model, coordination and prefabricated producers explained under condition punishment incentive. The results indicate that stable strategies exist noncooperation, are influenced by initial proportion decision‐making processes. government can...

Real-time detection of workers is crucial in construction safety management. Deep learning-based detecting methods are valuable, but always challenged by the possibility target missing or identity errors under complex scenarios. To address these limitations, previous research depended on re-training for new models datasets, which prohibitively time-consuming and incur high computing demands. However, we demonstrate that better model might not rely more weights; instead, a training-free can...

With the increasing popularity of prefabricated buildings, more and precast plants have been equipped with multiple production lines to increase productivity meet growing market demand. Sharing equipment, human, transportation resources is a typical feature integrated scheduling management for on lines. In response these characteristics, this article studies optimization multi-line components. on-time delivery lower costs as goals, mathematical model established scenario. This adopts genetic...

The frequent occurrence of various urban disasters poses risks to human survival and welfare, it is great significance evaluate the medical system carrying capacity (UMSCC), monitor spatial temporal patterns UMSCC identify their obstacle factors improve public rationalize resource allocation. In this paper, Yangtze River Delta agglomeration (YRDUA), which includes 27 major cities, taken as a case study. A evaluation model constructed gravity center shift trajectory analyzed by using ArcGIS...

The potential of emerging information technology has been proposed by many researchers and practitioners in the construction industry, including smart construction. Meanwhile, acceptance use is one major subjects for current study practice. Furthermore, although there are applications benefits development system, issue that it unclear why this adopted, factors enhance its implementation unknown. Therefore, an model (EITAM) was proposed, our hypotheses were tested structural equation modeling...

Purpose The purpose of this paper is to identify risk factors in building information modeling (BIM) technology application, analyze the correlation between factors, and find most influential using interpretative structural model (ISM), put forward a response targeted suggestions, provide reference for widespread BIM application. Design/methodology/approach Literature reviews, ISM, questionnaire survey expert interviews were used paper. First, application their relationships determined by...

Due to the more complex structure, greater size, and longer constructing period, most construction projects are facing risks than before need effective methods tools manage risks. However, because of mathematic formulas, difficulty collecting data , or low profit margin etc., professionals finding that few risk management sufficient, they typically rely on their experience in practical construction-project management. To solve these problems, we present Building Information Modeling (BIM) as...

This study establishes a tripartite evolutionary game model based on the assumptions of bounded rationality and interaction behavior governments, owners, general contractors to examine how strategies are changing for three stakeholders regarding building information modeling (BIM) application in engineering-procurement-construction (EPC) projects. The theoretical was validated effects critical factors stakeholder decision making were discussed using case numerical simulation analysis....

As a sustainable and cleaner type of facility, prefabricated buildings face more design barriers than traditional non-prefabricated buildings. Identifying managing these is key to improving the success rate building design. However, direct studies on are extremely rare. The present study solved this problem by combining multiple methods, including grounded theory (GT), structured self-intersection matrix (SSIM), analytic network process (ANP), linear weighted sum method (LWSM). GT was...

As its relatively large storage capacity and the ability of identifying tracking materials equipment in real-time without any direct contact or line-of-sight compared to traditional bar codes, Radio frequency identification (RFID) technology has been more adopted many sectors identified as one ten greatest contributory technologies 21 st century. To systematically shed light on potential applications RFID for uninitiated readers, this paper first presents principle brief history technology....

It has been found that a low level of trust among members construction project team leads to poor performance in China. Many researchers have described the challenges, consequently advocating partnering as an attractive approach for more valuable cooperation. Because substantial investments poured into projects since year 2000, research will improve and be meaningful Chinese industry.The purpose this paper is investigate attributes affecting owners' contractors, understand potential...

As an effective way to reduce costs and increase efficiency of EPC projects, BIM technology has drawn a lot attention in numerous countries. Existing studies have failed reveal the decision‐making mechanisms owners general contractors projects dynamic method. This study investigates underlying logic collaboration application by analyzing behaviors based on evolutionary game model. The results show that most suggestions promote are “increasing proportion initially strategies,” incremental...
