This paper adopts the stochastic simulation method that pertains to geostatistics, on the basis of simulated DEM realizations with spatial autocorrelation errors, to explore the error propagation mechanism of DEM-DON-DLG under the digital photogrammetry environment. It follows this procedure: first, produce 100 error-disturbed DEMs by means of sequential Gaussian simulation; next, attain 100 re...

The importance of proper verification and validation (V&V) of simulation models and experiments is well accepted in the modeling and simulation community. There is currently a push to improve the scientific aspects of modeling and simulation, including validation. To determine the amount of validation performed in practice, we analyze 110 health care simulation papers from the last eight years ...
