An object oriented library for sawmill simulation

This work shows an object oriented library that was designed to facilitate the development of simulation studies of sawmills. A group technology approach was used to minimize the number of objects in the library, which includes objects that have the functionality of the equipments found in these facilities, so that the analyst only needs to provide the layout, locate the transports and machines, and insert the parameters of the process. For large sawmills having state of the art production equipment, with optimization capacities in each machine, two applications of the library are shown. The study demonstrates the advantage of using an object orientation, and the usefulness of simulation is a tool for aiding in both the design and in the improvement of the operations of these facilities.
