Study of the factors that affecting automobile seat comfort

Research and development of automobile seat comfort is generally still focused on the ergonomics aspect. Whereas consumers expectations for automobile seat comfort will continue to rise, so focus on ergonomics aspect are still inadequate to meet these expectations. Therefore, it is necessary to research and assessment of automobile seat comfort based on other factors that are based on consumers preferences. Consumers preferences have qualitative nature. In this research, a heuristic method is applied to make consumers preferences in the numeric value (quantitative). The heuristic method is combination method of Analytic Hierarchy Procedure (AHP), Entropy method and Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS). The heuristic method is applied to obtain the weight of each factor and assess the comfort of alternatives, but in this research the results obtained are still in the process of weighting factors. Based on these calculations, the most influential factor on automobile seat comfort is social factor.
