Earthmover-Simulation Tool for Earthwork Planning
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 ...
متن کاملOptimized Earthwork Planning Methodology for Land Development Projects
An earthwork for land development projects, which possesses around 20% of the total project cost, consists mainly of simply repetitive tasks such as loading, hauling, dumping, and returning and depends largely on heavy construction machines. The goal of earthwork planning is to minimize the project cost and duration by determining soil allocation, equipment configuration, and haul route. Due to...
متن کاملEnvironmental impact of geometric earthwork construction in pre-Columbian Amazonia.
There is considerable controversy over whether pre-Columbian (pre-A.D. 1492) Amazonia was largely "pristine" and sparsely populated by slash-and-burn agriculturists, or instead a densely populated, domesticated landscape, heavily altered by extensive deforestation and anthropogenic burning. The discovery of hundreds of large geometric earthworks beneath intact rainforest across southern Amazoni...
متن کاملFeatures and Formulae
Feature structures are a representational device used in several current linguistic theories. This paper shows how these structures can be axiomatized in a decidable class of first-order logic, which can also be used to express constraints on these structures. Desirable properties, such as compactness and decidability, follow directly. Moreover, additional types of feature values, such as "set-...
متن کاملFramework for an intelligent earthwork system Part I. System architecture
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...
