Recent Research in Experimental Design for Quality Improvement with Applications to Logistics.

The success of Japanese industry in producing high quality products at low cost is cited. Consideration of certain aspects of scientific method leads to discussion of recent research on the role of screening designs in the improvement of quality. A projective rationale for the use of these designs in the circumstances of factor sparsity is advanced. In this circumstance the possibility of identification of sparse dispersion effects as well as sparse location effect is considered. A new method for the analysis of fractional factorial designs is advanced. Author
