A measuring model of process capability to consider sampling error

[[abstract]]Most products have multiple characteristics, and customers accept products whenever all process capabilities of each characteristic satisfy preset specifications. Obviously, univariate process capability indices cannot meet the requirements stated as above. And Chen et al. (2001) used point estimation to evaluate process capability, even though the method agrees with 100% tests. If the check is sampling, the process capability must consider sampling error. So the research constructs a measuring model of process capability to consider sampling error to evaluate process capability for a multi-process produce based on Cpk which was proposed by Kane (1986).[[notice]]補正完畢[[incitationindex]]E

Applied Product Capability Analysis Chart in Measure Step of Six Sigma

[[abstract]]This paper will apply product capability analysis chart PCAC in Measure step of Six Sigma. Because the test model is sampling, sampling error must be consider. Thus minimum value will be used to evaluate process capability. Besides the paper used minimum value to evaluate process capability, we also applied the concept of Six Sigma in PCAC and construct PCAC of Six Sigma standard. Finally, PCAC of Six Sigma standard will apply in Six Sigma project of Offset Ratchet Wrenches which manufactured by Y company.[[incitationindex]]SCI[[incitationindex]]SSCI[[booktype]]紙
