Analyzing quality-control trends with moving slope charts.
We have developed and evaluated a new procedure for detecting trends in quality-control measurements and applied it to laboratory data. The method requires the use of sequential or "moving" slope estimates to identify trends. Formulae are derived to estimate the regression error for the moving slope directly from the standard deviation of the analytical measurements obtained during characteriza...
متن کاملControlling Quality in Software Inspections using Control Charts Controlling Quality in Software Inspections using Control Charts
Software inspections are an efficient way of controlling and reducing the number of faults throughout the software life cycle [Ebenau94a]. A process, more or less stable and formal, is used when inspecting a document and by using statistical quality control [Mills88] the software inspection process can be monitored. Further, an early warning system can be implemented into organisations which ca...
متن کاملNonparametric Shewhart-type Quality Control Charts in Fuzzy Environment
Nonparametric control charts are presented in order to figure out the problem of detecting changes in the process median (or mean), or changes in the variability process where there is limited knowledge regarding the underlying process. When observations are reported imprecise, then it is impossible to use classical nonparametric control charts. This paper is devoted to the problem of c...
متن کاملFUZZY CONTROL CHARTS FOR VARIABLE AND ATTRIBUTE QUALITY CHARACTERISTICS
This paper addresses the design of control charts for both variable ( x chart) andattribute (u and c charts) quality characteristics, when there is uncertainty about the processparameters or sample data. Derived control charts are more flexible than the strict crisp case, dueto the ability of encompassing the effects of vagueness in form of the degree of expert’spresumption. We extend the use o...
