Application of Paulownia wood based on fuzzy theory decision-making

This study examined parental and children’s perceived value preferences regarding wooden toy materials to facilitate more efficient toy selection while evaluating whether fast-growing Paulownia wood can serve as a valuable alternative to high-consumption timber species to promote green toy adoption. The research employed three common wood types used in toys, furniture, and construction – ash, beech, and Paulownia – to fabricate experimental toy prototypes. Through on-site observations and questionnaires, parental preferences were documented across five dimensions: surface characteristics, price, usage cycle, environmental friendliness, and suitability. Results were analyzed using fuzzy theory for data recording, SPSS 27 for descriptive statistics, and fuzzy analytic hierarchy process for solution validation. Findings indicate that while Paulownia showed slightly weaker advantages in surface characteristics and modest benefits in usage cycle and suitability, it demonstrated significant advantages in price competitiveness and environmental performance, suggesting substantial potential for wider adoption.
