Robust sequential bifurcation (RSB) is an outlier-resistant factor screening method. It combines robust statistics with the sequential bifurcation procedure, which can handle the factor screening problem when response data is contaminated. Due to the low relative efficiency of robust estimator (median & MAD) and apparent discrepancy between the rob...

The conventional sample range is widely used for the construction of an R-chart. In an R-chart, the sample range estimates the standard deviation, especially in the case of a small sample size. It is well known that the performance of the sample range degrades in the case of a large sample size. In this paper, we investigate the sample subrange as...

The continuous-space single- and multi-facility location problem has attracted much attention in previous studies. This study focuses on determining the globally optimal facility locations for two- and higher-dimensional continuous-space facility location problems when the Manhattan distance is considered. Before we propose the exact method, we sta...
