Development of a rule-based inference model for human sensibility engineering system

Human Sensibility Engineering System (HSES) has been applied to product development for customer’ s satisfaction based on ergonomic technology The system is composed of thiee parts such as human sensibility analysis, inference mechanism, and piesentatton technologies Inference mechanism translating human sensibility into design elements plays an important role in the HSES In this paper, we propose a rule-based inference model for HSES The rule-based inference model is composed of five rules and two inference approaches Each of these rules reasons the design elements for selected human sensibility words with the decision variables from regression analysis In terms of forward inference These results are evaluated by means of backward inference By compaiing the evaluation results, the inference model decides on product design elements which are closei to the customer 's feeling and emotion Finally, simulation results are tested statistically in oider to ascertain the validity of the model
