Combining Simulation and Optimization Models for Hardwood Lumber Production

Abstract

Published literature contains a number of optimization and simulation models dealing with the primary processing of hardwood and softwood logs. Simulation models have been developed primarily as descriptive models for characterizing the general operations and performance of a sawmill. Optimization models, on the other hand, were developed mainly as analytical tools for prescribing optimal production plans but with minimal concern on real-time day-to-day operations of a sawmill. This paper describes a combined simulation and optimization model that considers both the determination and the implementation of optimal production schedules. Emphasis centers of the performance and utilization of various machine centers, including production delays, buffer decks, queue capacities, operating time, and equipment and resource utilization.
