MTS法を利用した操作レバーの最適化設計

―MTシステムによる使用感の設計―

抄録

By using the MT system, we measured product usability, which is said to be difficult to perform, we quantified the contribution ratio of each design parameter to usability, and then we designed the parameter for the optimum usability. The usability of an operating lever for a receipt printer was optimized. The product that was optimized was examined by both calculation of the MT system and test subjects of the real sample. In both tests, extremely desirable results were obtained. To minimize the burden on the test subjects, the number of the test samples was small, resulting in multicollinearity in the calculation. However, a unique measure was taken to obtain the preferred result. As a result of this examination, the optimal usability was ensured even with a small number of parts, and furthermore cost reduction was realized. In the future,this method can be widely applied as a method to design a product and obtain the optimal usability.
