Testing capability indices for one-sided processes with measurement errors
In the manufacturing industry, many product characteristics are of one-sided tolerances. The process capability indices C p (u, v) and C l p(u, v) can be used to measure process performance. Most research work related to capability indices assumes no gauge measurement errors. This assumption insufficiently reflects real situations even when advanced measuring instruments are used. In this paper...
متن کاملTesting capability indices for manufacturing processes with asymmetric tolerance limits and measurement errors
Most research works related to process capability indices assume no gauge measurement errors. However, such an assumption inadequately reflects real situations even when advanced measuring instruments are employed. If we do not take into account these errors, conclusions drawn from process capability are therefore unreliable. In this paper we study the sampling distribution of capability indice...
متن کاملOne-sided Process Capability Assessment in the Presence of Measurement Errors
In the manufacturing industry, many product characteristics are of one-sided specifications. The well-known process capability indices CPU and CPL are often used to measure process performance. Most capability research works have assumed no measurement errors. Unfortunately, such an assumption is not realistic even if the measurement is conducted using highly sophisticated advanced measuring in...
متن کاملOne-sided Process Capability Assessment in the Presence of Gauge Measurement Errors
Montgomery [31] recommended some minimum quality requirements on . For existing processes, the capability must be no less than 1.25, and for new processes, the capability must be no less than 1.45. For existing processes on safety, strength, or critical parameters, the capability must be no less than 1.45, and for new processes on safety, strength, or critical parameters, the capability must be...
متن کاملProcess Capability Analysis with Focus on Indices for One- sided Specification Limits
In this thesis some aspects of process capability analysis are considered. Process capability analysis deals with how to assess the capability of manufacturing processes. Based on the process capability analysis one can determine how the process performs relative to its product requirements or specifications. An important part within process capability analysis is the use of process capability ...
