碩士 === 崑山科技大學 === 企業管理研究所 === 93 === The purpose of this study is tried to improve the inequality loads between instep and sole. We chose Ching-lhu, the biggest ODM factory of adidas as our case study. At first, we sent questionnaires to the cadres of quality control department and producing department and got the potential critical factors through the questionnaires. We used DMAIC of Six sigma as the study steps. In the improvement section, we found the better loads through the Taguchi method and then used Response surface mythology to adjust the findings of Taguchi method to get the best loads. For WB: The best loads are: presing of marking(2.5 kg), using time of prime(1 hr), using time of cement(1 hr), toe last sword tempareture(50 ℃), sole attaching time(120 sec), deposited time(7.5 min), prime oven’s upper tempareture(57.5 ℃), presure of water pressing(9 kg), time of water pressing(5 sec), presure of sole attaching(37.5 kg), time of sole attaching(13.5 sec), prime oven’s bottom tempareture(62.5 ℃), cement oven’s upper tempareture(55 ℃), cement oven’s bottom tempareture(65 ℃). For TFA: The best loads are: presing of marking(2.5 kg), using time of prime(1 hr), using time of cement(1 hr), toe last sword tempareture(50 ℃), sole attaching time(120 sec), deposited time(7.5 min), prime oven’s upper tempareture(67.5 ℃), presure of water pressing(9 kg), time of water pressing(6 sec), presure of sole attaching(37.5 kg), time of sole attaching(13.5 sec), prime oven’s bottom tempareture(62.5 ℃), cement oven’s upper tempareture(55 ℃), cement oven’s bottom tempareture(65 ℃). Producing through the loads above, the sigma level of the factory is improved from 3.2 sigma to 4.5 sigma.
