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...

Purpose The development of communication and artificial intelligence technologies has raised interest in connectivity increased autonomy automated earthmoving equipment for earthwork. These changes are motivating work to reduce uncertainties, terms improving object detection capability reducing strikes accidents on site. purpose this study is illustrate industrial drivers earthwork systems; ide...

Despite of the advances in construction planning and scheduling software, construction managers and planners are still facing problems in achieving accurate planning, scheduling and costing due to the one-off nature of the construction projects and the inherently uncertain site conditions and soil characteristics. The aim of the research presented in this paper is to introduce a new methodology...

This paper presents EarthMover, a discrete-event special-purpose simulation modeling tool for earthwork planning geared towards practitioners. The paper explores the capabilities of the system by modeling an earth moving operation of moderate complexity. The operation is initially modeled with default parameters and is sucessively improved based on insights obtained from the static and dynamic ...

Earthwork projects involve moving specific amounts of earth from a discrete set of source locations to a discrete set of destinations. Constructors use different methods and equipment to move earth depending primarily on haul distance and equipment availability. Successful earthwork projects involve successively refined cycles of construction plan preparation and evaluation. The construction pl...
