If this sounds like a familiar scenario at your mill or plant, please acquaint yourself with Metso Factor Network Analysis Tool (Metso FactNet). Metso FactNet is Metso's powerful data analysis software that can allow you to unlock the process information stored away in your historical operating data. Metso FactNet is a multivariate analysis system designed for analyzing large amounts of interrelated process and quality data. Metso FactNet combines multivariate statistics with a sophisticated pattern recognition system. The pattern recognition system allows users to incorporate their own process expertise into the system, creating robust and accurate process models. The Metso FactNet models quantify the effect of process and operating conditions on final quality and operating costs. Once Metso FactNet models have been developed, the Metso FactNet Optimizer can be used to determine the optimum operational parameters to minimize operating costs while meeting quality or operational constraints. Off-line Analysis Off-line troubleshooting involves tapping into historical mill information that contains process variables and/or quality variables of interest and applying the Metso FactNet tools to identify where the disturbance is coming from and what effects that change has had on the rest of the process. On-line Analysis In addition to this type of off-line analysis, Metso FactNet has been used in a wide range of on-line applications in the pulp and paper as well as the power industry. On-line implementation for analysis, control and optimization requires a wide range of capabilities to provide robust, accurate and maintainable systems.
