RESOURCE-ORIENTED MODELING AND SIMULATION IN CONSTRUCTION

In modeling for simulation, the proper representation of crucial real- world variables is of prime importance. This paper describes the creat ion of a model that allows simulation of the construction process to b e conducted in a simple fashion, in the field, and in a way that is or iented to the attributes of the specific resources available for the p rocess. The developed model uses resources and their attributes as var iables. This allows for consideration of resources of different sizes for the same work task, calculation of running task durations during s imulation, rule-based release of resources from queues, and maintenanc e of detailed statistics on each type and size of resource used in the system. Experimentation with established equipment mixes and conditio ns as shown in published handbooks for earthwork processes has verifie d the capability of the system to predict production rates for differi ng equipment mixes and site conditions.
