| Abstract: | Product competitiveness is the most important concern for industry and is decided by the interaction of engineering activity with the market environment. This paper describes the characteristics of technological product competitiveness in the market, by use of an ordinal scaling method based on rivalry comparison. The analysis was made for actual data extracted from data on consumer electrical products evaluated over a long period of time. Four methods were examined to quantify ordinal data for competitive evaluation elements. The maximum correlation ratio method was proved to be most reasonable for extracting detailed characteristics regarding product competitiveness in the market. It was also confirmed how the highest and lowest rankings in some element influence total competitiveness. The most competitive product in the electrical consumer market gets the highest ranking in performance evaluation, first or second ranking in timing, and above average ranking in cost, with no major setback in reliability. |
