Integrating Economic Performance and Process Simulation Models in Evaluating Sawmill Design Alternatives
Keywords:Process simulation, machine breakdown, economic performance
AbstractThis paper describes a simulation study that combines an economic performance measure and a process simulation model. This integrated approach is capable of capturing the operational and cost behavior of a sawmill system over time by taking into consideration the effects of the stochastic occurrence of machine breakdowns and other processing delays. The method is demonstrated using an actual design problem involving a profiler chipper-canter mill.
