Real-time quality control system for automated lumbermills

This paper describes a system under development for real-time sawmill production monitoring using existing process control equipment. The resulting system ties together various machine centers in a sawmill by using marking and reading techniques that are similar to barcoding, and a PC-based expert system that will collect information from the machine centers and provide real-time advice to supervisors and maintenance personnel. The system provides both a real-time quality control function and monitoring function to ensure that the correct production strategy is being followed to match marketing plans.
