Abstract: Understanding the ergonomic needs of passengers and driver of a car has widespread implications. For this, the major ergonomic attributes of a car need to be identified and prioritised. Twenty ergonomic attributes were identified and the voice of customers (VoC) about these attributes was captured from consumer survey based on fuzzy Kano model. The results of the survey were integrated with quality function deployment (QFD) to develop a new framework 'house of ergonomics deployment (HED)', which prioritises these attributes. These priorities are compared with the priorities obtained from fuzzy analytic hierarchy process (FAHP). Car manufacturers and automobile designers can use these priorities during the product development phase, for improving the ergonomic appeal of a car and to stay ahead in the competition. Prospective buyers can be benefited by comparing the ergonomic attributes among the various models of car.

Keywords: automobile design and development; car ergonomics; fuzzy Kano model; quality function deployment; QFD; fuzzy AHP; prioritising attributes; systems.
