TAILIEUCHUNG - Simulation of forest harvesting alternative processes and concept design of an innovative skidding winch focused on productivity improvement
In contexts in which mechanized harvesting is limited, such as in the northwestern Black Sea region of Turkey, it is important to improve timber harvesting productivity while preserving operators’ safety and reducing environmental damage. This study aims to introduce a methodology in which the harvesting process is simulated with discrete-event simulation (DES) software in order to identify bottlenecks. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2015) 39: 350-359 © TÜBİTAK doi: Simulation of forest harvesting alternative processes and concept design of an innovative skidding winch focused on productivity improvement 1, 1 1 Giuseppe DI GIRONIMO *, Alessio BALSAMO , Gianpiero ESPOSITO , 1 2 3 Antonio LANZOTTI , Kenan MELEMEZ , Raffaele SPINELLI 1 Department of Industrial Engineering, University of Naples Federico II, Naples, Italy 2 Department of Forest Engineering, Bartın University, Bartın, Turkey 3 Trees and Timber Institute, National Research Council of Italy (CNR IVALSA), Sesto Fiorentino, Italy Received: Accepted: Published Online: Printed: Abstract: In contexts in which mechanized harvesting is limited, such as in the northwestern Black Sea region of Turkey, it is important to improve timber harvesting productivity while preserving operators’ safety and reducing environmental damage. This study aims to introduce a methodology in which the harvesting process is simulated with discrete-event simulation (DES) software in order to identify bottlenecks. An alternative process is compared to the original within the DES software, carrying out further steps oriented to the generation of new innovative product concepts. As a case study, the design of an innovative skidding winch is proposed. The development of the product was focused towards customer satisfaction by collecting customer requirements and identifying quality characteristics with a quality function deployment approach. Contradictions identified in the design phase were solved using the TRIZ contradiction toolkit, generating different product concepts. Inventive solutions provided by TRIZ were designed within parametric CAD software. The concepts were compared in a virtual environment, eventually selecting an optimal solution. The results showed that, with
