The Method for Selecting Multiple Suppliers Using One-sided Specification LimitBs Capability Index

Abstract

The potential supplier is an important for manufacturing process. This paper presents a new methodfor selecting multiple suppliers using one-sided specification limitos capability index (Cpu or Cpl ). This studydefined 4 parameters such as the number of suppliers, Cpu index, sample size and significant level (α).A Monte Carlo simulation with 10,000 runs under various situations was conducted for investigating.The proposed method provided actual Type I error rate close to the pre-defined significant level (α) for allsimulated cases.
