Development of planning system for plywood production using “matrix designer”

The paper describes research and development of a software system for plywood mill operation planning. Various tasks related to planning of plywood operation can be successfully solved with the use of specialized software. The paper describes solution of the problem of calculating monthly production plans, which requires the use of advanced mathematical models and optimization algorithms. Therefore, special attention is devoted to the “matrix designer” - a special data structure for improving the efficiency of storing and using data by taking into consideration the block structure of constraints matrix. The paper also includes description of the system. The efficiency of the system had been confirmed on real operating data of plywood mills. The use of “matrix designer” allowed to speed up and simplify modification of the mathematical model while clarifying technical features of the mill.
