摘要: | 供应商选择问题是在处理与比较两个制程的差别,并且选出一个制程能力较高者当成所属之供应商。其中,良率是一个被广泛运用于制程表现的绩效指标。在此篇研究中,我们面对多品质特性的供应商选择问题时,藉由使用良率指标 来比较两个供应商的制程优劣,并选出两者之间其产品拥有较高良率的一方做为我们所选择的供应商。在此,我们使用两个阶段的假设检定来做抉择,并且提供在实行假设检定时所需要的临界值,以作为供应商选择的判定标准。另外,为了使检定力得以在可容许范围内,我们亦提供了所需要的抽样样本数。这些成果将会使业界或使用者在做这类问题时更加方便,并且准确。最后,我们运用并说明在现实工厂里的一个实际例子,来比较两个供应商如何做选择,并验证此研究的可行性。 Supplier selection is to deal with comparing two processes and selecting the one that has a significantly higher capability value. Process yield has been widely used on process performance. In this paper, we consider the supplier selection problem with multiple characteristics by using the yield index to compare two production processes and select one that has higher production yield. Testing hypotheses with two phases for comparing two processes are considered. Critical values of the testing hypotheses are calculated to determine the selection decisions. Sample size required for a designated selection power and confidence level is also investigated. These results provide useful information to practitioners. An application example on comparing two production processes is presented to illustrate the practicality of the proposed approach to a real problem in the factory. |
