Simulation Demos

Selected Animations of Simulation Studies

This page contains several animations of simulation studies performed using STROBOSCOPE or higher-level simulation tools built on top of STROBOSCOPE. To view these animations, it is necessary to download and install the Proof Demo Viewer.

The Moneta By-pass

(587 KB)

This is an animated presentation of a simulation study that measures the impact of a change in the regulations imposed by a railroad authority on the usage of a temporary railroad crossing by a highway contractor. The study was performed by Haldun Cor and is described in detail in his Masters Thesis.

The Devil is in the Deviations

This animation illustrates the effect of variability in the productivity of an earthwork operation. An initial and perfectly balanced case illustrates a "dream world" in which there is no variability in excavation, travel, and dumping times. Other cases with the same fleet but with various coefficients of variation applied to these times illustrate the queuing and resulting production loss that results when probabilistic activity times are used.

The long narrow curve

This animation is produced by StroboDirt, a programmable special-purpose simulator for earthwork operations based on STROBOSCOPE. The showcased simulation study explores the dynamic decisions and complex logic that can be modeled with StroboDirt. To view, run the self-extracting archive and open “Curve.psf” from within Proof. You can also interactively run this model over the web .
