Regional integrated energy site layout optimization involves multi-energy coupling, multi-data processing and multi-objective decision making, among other things. It is essentially a kind of non-convex multi-objective nonlinear programming problem, which is very difficult to solve by traditional methods. This paper proposes a decentralized optimization and comprehensive decision-making planning strategy and preprocesses the data information, so as to reduce the difficulty of solving the problem and improve operational efficiency. Three objective functions, namely the number of energy stations to be built, the coverage rate and the transmission load capacity of pipeline network, are constructed, normalized by linear weighting method, and solved by the improved p-median model to obtain the optimal value of comprehensive benefits. The artificial immune algorithm was improved from the three aspects of the initial population screening mechanism, population updating and bidirectional crossover-mutation, and its performance was preliminarily verified by test function. Finally, an improved artificial immune algorithm is used to solve and optimize the regional integrated energy site layout model. The results show that the strategies, models and methods presented in this paper are feasible and can meet the interest needs and planning objectives of different decision-makers.

The Impact

Construction 4.0 (a concept of Industry 4.0) is an ongoing transformation that aims at digitalization and automation of traditional construction and industrial practices using modern smart technology. The technological development especially of the construction sector is of utmost importance to meet the requirements of rapid construction projects aiming at quality work, increased productivity, and cost savings. One such technology that has come to the limelight is Virtual Reality (VR), which is a computer-generated smart environment that is artificially created using various types of hardware and software. This smart environment is created to resemble a real-life structure that can be explored, visualized, and interacted with by users using electronic devices for better decisionmaking before actual construction. The purpose of this paper is to design a Virtual Reality model using Building Information Modelling (BIM) and to examine the impact and influence of Virtual Reality Technology in the Indian construction industry with the help of a questionnaire survey. This study provides necessary information for implementing Virtual Reality technology in the construction industry. The results of this study provide a research road map to researchers for their future efforts.

A good arrangement of site layout on a construction project is a fundamental component of the project’s efficiency. Optimization on site layout is necessary in order to reduce the transportation cost of resources or personnel between facilities. Recently, the use of bio-inspired algorithms has received considerable critical attention in solving the engineering optimization problem. These methods have consistently provided better performance than traditional mathematical-based methods to a variety of engineering problems. This study compares the performance of particle swarm optimization (PSO), artificial bee colony (ABC), and symbiotic organisms search (SOS) algorithms in optimizing site layout planning problems. Three real-world case studies of layout optimization problems have been used in this study. The results show that SOS has a better performance in comparison to the other algorithms. Thus, this study provides useful insights to construction practitioners in the industry who are involved in dealing with optimization problems

Assembly Performance

The use of a 4D schedule as technological advancement has brought significant improvement to the planning and execution of construction projects, through visualizing step-wise construction progress, following a sequence of pre-planned activities, and finalizing a baseline schedule with necessary changes. Moreover, the application of immersive virtual reality (IVR) to create an interactive 4D BIM schedule of a planned structure has made it possible to create a detailed plan of any construction project. Because of these benefits, the use of 4D schedules and immersive virtual reality in the construction industry has increased, leading to improved planning and execution. However, past studies have given little attention to the applications of such technologies on modular projects. Thus, this research applied a 4D schedule, along with immersive virtual reality, on a modular project, and verified their benefits and effectiveness. The results showed that most of the participants who experienced a 4D BIM schedule, along with immersive virtual reality (4D/IVR), strongly agreed that it is an easy and straightforward way to visualize the project, understand the schedule, and find any errors. Moreover, while fewer than half of the participants scheduled the assembly sequence correctly with conventional schedule and 2D drawings, almost all of them sequenced the assembly successfully with 4D/IVR. Based on the findings, this research concludes that the implementation of a 4D BIM schedule, along with virtual reality technology, can enhance the fabrication and assembly performance of modules.
