ABSTRACT: Accurate and visual information of working locations is vital for efficient resource planning and location-based scheduling of earthworks, which is missing in existing linear schedules. Thus, construction managers have to depend on subjective decisions for resources allocation and progress monitoring from location aspects. This has caused uncertainties in planning and scheduling, and ...
Recently, there has been an increase in the demand to enhance the intelligence of construction equipment and systems. Especially for semiautonomous and autonomous systems that have great potential for impact on the construction industry, artificial intelligence approaches are required to generate instructions and plans necessary to perform tasks in dynamically changing environments on their own...
Improving safety and productivity of earthwork operations is of paramount importance, especially in congested sites where collisions are more probable. Automated Machine Guidance and Control technology is expected to improve both safety and productivity of earthwork operations by providing excavator operators with higher level of support regarding the path planning of excavators based on site c...
This paper applies an evolutionary algorithm, the particle swarm optimization (PSO), to design the optimum open channel section. Depth, channel side slope and bottom width are considered as the variables for rectangular, triangular and trapezoidal channels, respectively. The objective function is minimizing the construction cost of the channel section. MATLAB software is used for programming an...
One of the most important factors that affects construction costs of highways is the earthwork cost. On the other hand, the earthwork cost strongly depends on the design of vertical alignment or project line. In this study, at first, the problem of vertical alignment optimization was formulated. To this end, station, elevation and vertical curve length in case of each point of vertical intersec...
