第9章课后测验
1、which of the following statements is not true about the fundamental concepts of taguchi methods( ) a、quality should be controlled from three aspects: product design, process control, quality monitoring. b、quality should be designed into the product, and it does not come from inspection. c、quality minimizes the deviation from the target value and remains unaffected by the uncontrollable environment. d、quality costs should be measured by the function, which is expressed by the deviation from the target value.
