Software system for sawmill operation planning

The paper describes research and development of software system for optimal planning of sawmill operation. This work is a part of long-term activity carried out by Petrozavodsk State University (PetrSU) in the field of scientific research, software development and customer projects for enterprises of pulp-and-paper and forestry industry of Russia. The system uses advanced mathematical models and optimization algorithms, developed by IT-park of PetrSU, to solve a series of planning tasks for any number of orders and any configuration of process equipment of a hardwood sawmill. The developed mathematical model takes into account all features, limitations and parameters of process equipment, as well as of raw material and production orders. The efficiency of solutions had been validated on real production data of several sawmills in Russia. The system has friendly and flexible user interface and can be easily modified to handle new customer-specific requirements.
