Methods, apparatuses and systems that facilitate the design, production and/or measurement tasks associated with manufacturing and other processes. In one embodiment, the present invention provides an understanding of how the multiple characteristics of a given process output are related to each other and to process inputs. This knowledge facilitates a reduction in measurement costs. It also facilitates an understanding of the sometimes complex interrelationships between design targets, design tolerances, process inputs, process control variables, average process output and variation in the process output. As discussed in more detail below, embodiments of the present invention facilitate 1.) determination of design target values, 2.) determination of design specification limits, 3.) design of process inputs, 4.) determination of process control variable settings, and/or 5.) reduction of measurement costs. |

1. An apparatus facilitating design, manufacturing, and other processes comprising:
a processor; a memory; a software application, physically stored in a computer-readable storage medium, comprising instructions operable to cause the processor and the apparatus to:
receive into the memory a plurality of article characteristic values associated with a set of articles having a range of variation as to a plurality of article characteristics resulting from a process;calculate correlation coefficient values characterizing correlations between the plurality of article characteristics;calculate predictor capability values for the plurality of article characteristics, wherein the predictor capability value for a given article characteristic is a function of the correlation coefficients corresponding to the given article characteristic;receive a selection of a predictor characteristic from the plurality of article characteristics based on the correlations between the plurality of article characteristics; and,determine the regression model(s) between the predictor characteristic and at least one of the remaining article characteristics in the plurality of article characteristics; andidentify a range for the predictor characteristic over which at least one remaining article characteristic is within design specifications. |
