Introduction of Application Cases of Conference Matrices to Quality Improvement Research

Using the conference matricesConference matrices reduces the number of experiments to 1/3 to 1/2 of the mixed orthogonal arrayOrthogonal array. About 90% of the research subjects are qualityQuality improvement and processProcess improvement such as new product development, productivity improvement, elimination of pollutants, and defective product countermeasures by changing conditionsCondition. This chapter explains qualityQuality improvement research with the case studies related to 90%.
