Abstract : The current paper assesses a log yard design methodology. The method is derived from a procedure developed in the early 1980’s and is updated using simulation software and analytic tools which allow for a more thorough evaluation of yard performance. The purpose of the proposed method is to offer a rigorous procedure for log yard design and to assist the industry in making decisions concerning log yard operation. The methodology used in this experiment is divided into six steps: 1 collecting data on resources and relevant activities, 2 modeling material flow, 3 establishing flow priorities, 4 determining the required space for each activity, 5 developing preliminary plans and 6 evaluating said plans using simulation modeling tools. The method was carried out in partnership with a forest product company which was considering options for mill yard improvements. Results indicate that the methodology is useful to guide decision makers when developing a log yard design. Moreover, integrated with simulation tools, it provides for a robust evaluation of log yard performance through investigations using sensitivity analysis. Finally, handling equipment capacity and the dynamic interaction between each activity within the yard can now be determined and observed, which was not possible with previous methods.
