This paper presents a study of the fuzzy analytical hierarchy process (FAHP) for theprioritization of factors having important effects on the surface roughness of wood andwood-based materials in the planing process. Firstly, a three-level hierarchical model wasdevised. Secondly, the FAHP method was employed to determine the weights of thefactors. Finally, the prioritization of the factors was carried out taking into account theweights. The results showed that the most significant factors are feed speed (0.300),tool geometry (0.222), and material defect (0.107). Consequently, this study provides avaluable guide to the wood industry to improve the surface quality of wood and woodbasedproducts.
