Simulation study of production process in the sawmilling industry

Abstract

The production processes in primary sawmilling consist of a series of time-related technological operations, where logs are processed into lumber. The basic machines involved in these processes are power saws and band saws with great processing capacities, as a result of which bottle-necks and discontinuities may occur in further processing. In practice in the wood industry, problems of this kind are resolved during the design of the technological process where the known methodology is most efficiently used (8). This work suggests an additional methodology simulation study, whose results will be used as corrective arguments during the final decision making. The simulation study enables us to observe how the given technological process operates in due time and the influence of relevant factors on the operations and dynamics of the system based on results obtained in several experiments. The simulation language GPSS/FON is used for the performance of the observed model. Results are presented in tables and graphs.
