Abstract
In this research, we analyzed the automotive market bringing the automotive performance from about 300000 models from which they were open to the public from 1982 to 2006 years about 20000 models by Data Envelopment Analysis. DEA is the method that can make clear about superiority or inferiority of business unit with multi-dimensional index and showing improvement of business unit. As a result, we can show trends from graph where horizontal axis was assigned as each performance index and vertical axis was assigned as each efficiency value obtained by DEA. We showed design index of automotive in the future by sensitivity analysis. From the above-mentioned method, we can confirm DEA is the effective method as method of evaluating products with multidimensional index.
