Patient perceptions of health care quality are critical to a health care service provider's long-term success because of the significant influence that perceptions have on the outcome of the healthcare process and on patient behavioral decisions. It is a critical strategy for health care...

Discrepancy measure can be utilized as a uniformity measure for comparing factorial designs. A so-called discrete discrepancy has been used to evaluate the uniformity of factorials. In this paper we give linkages among uniformity measured by the discrete discrepancy, generalized minimum...

The objective of this paper is to study the issue of lower bound of the wrap-around L2-discrepancy value on asymmetrical designs with two and three mixed levels. We present a new lower bound of wrap-around L2-discrepancy, and by numerical simulation and some examples, we show that our lower...

This article develops a new mechanism to foldover designs involving factors with multi-level. By exhaustive search we identify the optimal foldover plans. This paper aims to study the issue of the optimal foldover plans for three-level designs, in view of the uniformity criterion measured by the...
