Abstract:

Related to the building environmental quality and human health, the materials' comfort attribute and its scientific evaluation has of positive significance. The rough sets fuzzy evaluation method was introduced to evaluate the comfort level of ten kinds of common wood-based materials. First, the primary factor set that affect the comfort of wood-based materials was definited, and then it was minimized to a number of five by using the rough sets Skowron differential matrix. Fuzzy evaluation grade of all materials on comfort were achieved and sorted after the membership function and membership degrees were fixed. Finally, the final results were analyzed and grouped comparison with the radar chart aided. The combination of rough sets and fuzzy method provides a new evaluation method for better choosing and utilizing the wood-based materials according to whose comfort attributes.

Key words: wood-based materials, comfort level, rough sets theory, fuzzy evaluation
