Discrete-Event Simulation for Estimating Emissions from Construction Processes
Publisher: American Society of Civil Engineers
Abstract: Whereas estimating emissions from construction processes is crucial to evaluating emission-reduction plans, current approaches can only estimate emissions from an average rather than operational perspective due to an ...
Simulation-Based Estimation of Fuel Consumption and Emissions of Asphalt Paving Operations
Publisher: American Society of Civil Engineers
Abstract: Although energy saving and emission reduction are crucial for sustainable construction, asphalt paving operations are seldom evaluated in terms of fuel consumption and emissions. Current methods for estimating fuel consumption ...
Computer Vision–Based Disruption Management for Prefabricated Building Construction Schedule
Publisher: ASCE
Abstract: Prefabricated building construction (PBC) projects are prone to schedule delays and budget overruns due to disruptions. Hence it is necessary to timely detect and evaluate disruptions and respond in order to put a disrupted ...
Wind Tunnel Test on Cable Dome of Geiger Type
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents preliminary results of an aeroelastic wind tunnel test on a cable dome. The structural design of the model is given in detail. Similarity requirements based on dimensional ...
Particle Swarm Optimization for Construction Site Unequal-Area Layout
Publisher: American Society of Civil Engineers
Abstract: Layout of temporary facilities on a construction site is essential to enhancing productivity and safety, and is a complex issue due to the unique nature of construction. This paper proposes a particle swarm optimization ...
Permutation-Based Particle Swarm Optimization for Resource-Constrained Project Scheduling
Publisher: American Society of Civil Engineers
