Abstract: During the product planning stage in Quality Function Deployment (QFD), the final importance of the technical characteristics was crucial to optimize the whole House of Quality (HoQ) and to make configuration decisions for the next stage. Traditional methods didnt consider both market competitive evaluation information and technical competitive evaluation information. To deal with this problem, a method to determine the importance of technical characteristics was presented. With the information in the existing HoQ, by considering market competitive evaluation and technical competitive evaluation, based on the available linguistic terms and experts knowledge, the Artificial Neural Network (ANN) was introduced to realize neural network-based fuzzy reasoning, the final importance of the technical characteristics was determined by this new method. An example was given to illustrate the feasibility of the proposed method.

Key words: quality function deployment, importance of technical characteristics, competitive evaluation, artificial neural network, fuzzy reasoning
