Selection of time study methods for forest operations

Standardisation of worktime is an essential element used in modern forest management. First attempts of standardisation were developed for the industry. The solutions used in the earliest research have been constantly modified for several decades, in order to adjust them as much as possible to the diversified nature of forest works. The earliest time studies were conducted with the use of manual chronometers. As the techniques and technologies of forest works grew more advanced, the measurement means and accuracy standards hitherto applied appeared insufficient. Introducing video methods into analyses of work processes and application of computer-aided techniques in data processing resulted in a significant decrease in labour intensity of measurements and improved their accuracy. The standard to be achieved in the future is to complement the analyses in question with data generated by the computer operating systems, installed on multi-operational forest machines to control the wood processing.
