ABSTRACT
In the face of increased competition and globalization, supply chain management has become a crucial aspect of securing competitive advantage. Within this, the quality offered by suppliers is vital. Thus, in this paper, we develop a model to select the best supplier based on process quality from the perspective of the buyer. We first employ the process capability index , which can provide an exact measure of process yield, to evaluate the process quality of suppliers. However, must be estimated from preliminary samples or obtained subsamples. This increases uncertainty and can lead to miscalculation. To ensure the reliability of assessment, we derive the lower confidence limit of to serve as a standard of process quality assessment and construct a process capability analysis chart to select the best supplier. The chart also provides recommendations for process improvement to serve as a reference for suppliers with poor performance. Finally, we present two real-world case studies to demonstrate the practical applicability of the proposed method.

从采购公司的角度开发基于质量的供应商选择模型
摘要
面对日益激烈的竞争和全球化,供应链管理已成为确保竞争优势的关键方面。在这一点上,供应商提供的质量至关重要。因此,在本文中,我们开发了一个模型,可以从买方的角度根据过程质量选择最佳的供应商。我们首先采用过程能力指数,它可以提供过程收率的准确度量,以评估供应商的过程质量。然而,必须从初步样本或获得的子样本中估算出来。这增加了不确定性,并可能导致计算错误。为了确保评估的可靠性,我们推导了下限的置信度作为过程质量评估的标准,并构建过程能力分析图以选择最佳供应商。该图表还提供了流程改进的建议,以作为绩效不佳的供应商的参考。最后,我们提供了两个实际案例研究,以证明所提出方法的实际适用性。
