Abstract or Summary
  • Plywood production scheduling for years has been considered, more or less, a sacred activity in which only a select group of individuals with the experience and knowledge could take part. With the advancements in computer technology and related fields, the plywood industry is in a position where more people can become involved in an otherwise restricted area of production planning. The objective of this study was to design a computer-assisted scheduling package that feasibly schedules jobs through the four operations of a dry-end department. The program, which satisfies this objective, was modeled after a local plywood plant. Though, because of the size of the facility and the limitations of the mini-computer on which this program was developed, only a fraction of the plants entire product line was used. The analysis of the program concentrates on evaluating the feasibility issue. That is, two trial runs were conducted to determine whether the program could generate feasible schedules. The test results for both runs indicated that the computed schedules were feasible. However, this does not warrant its practical use in an actual mill environment. Further analysis indicated that the current heuristic for scheduling the patcher, jointer, and dryer operations is not suitable for ensuring satisfactory levels of machine utilization. One possible resolution that was cited is to reformulate this heuristic so that makespan is minimized.
