“…The system is used by a forestry company in Karelia. In [9,10], we provide the mathematical model and solution approach to optimizing the profit measured as revenue from the sale of products, net of harvesting, and transportation costs. During several case studies involving 198 sites and 14 machines harvesting up to 200,000 cubic meters from an available stock volume of about 300,000 cubic meters, an increase in profit by 5 to 10% was observed.…”

The paper describes a modular methodology for the design of manufacturing information systems (MIS) on the example of forestry industry. The need to develop such methodology is justified by the current demand of forestry companies to increase the return on investment in information systems implementation. The proposed modular design methodology makes it possible to design and implement MIS that takes into account the specifics of a forestry enterprise and is less expensive compared to competing solutions. The advantage becomes possible due to the use of an integrated modular approach to a wide range of forestry companies "many companies-one tool" based on universal integrated platform solutions. This approach uses a matrix relation of a specific forestry enterprise with a universal technological process. The novelty of the proposed methodology is the automation of developing the mathematical model of a forestry enterprise by choosing unified procedures from the available set and tuning the parameters to account for the specifics of a particular enterprise. This allows using a unified set of functional diagrams, which reduces the time and cost of designing and modifying MIS based on them. The consistent approach to selecting the unified procedures leads to obtaining the mathematical model of a forestry enterprise, which becomes the core of its MIS. Application of this methodology makes it possible to design, implement and scale MIS for forestry companies faster and cheaper than using traditional approaches.

This paper describes an approach to the optimal planning of wood harvesting and timber supply for forest companies of Russia. Software and tools successfully used in other countries (e.g., Finland, Sweden, Canada, etc.) are not as effective in Russian conditions for a number of reasons. This calls for the development of an original approach to solve this problem with respect to Russia’s specific conditions. The main factors affecting the operation of wood harvesting companies in Russia were determined. The optimization problem was formulated taking into account all important features of wood harvesting specific to the country. The mathematical model of the problem was formulated and analyzed. An important requirement is that the solution algorithm should find high-quality plans within short computation times. The original problem was reduced to a block linear programming problem of large dimension, for which an effective numerical solution method was proposed. It is based on the multiplicative simplex method with column generation within Dantzig–Wolfe decomposition and uses heuristics to determine feasible solutions based on the branch and bound method. We tested the solution approach on real production data from a forest company in southern Karelia with a planning horizon up to a year. This case study involved 198 sites and 14 machines harvesting up to 200,000 cubic meters from an available stock volume of about 300,000 cubic meters. An increase in profit by 5% to 10% was observed, measured as revenue from the sale of products, net of harvesting and transportation costs.
