Path Score Based Approach for Deriving Machine Sequence in Multistage Process

Path selection in multistage manufacturing process has a considerable impact on product quality because uniform product quality cannot be ensured across all equipment. Accordingly, we present a method for choosing the best path while taking product quality into account. In this paper, we firstly introduce a quality index and categorize product grades. Building upon the criteria, we also propose an approach based on path scores to identify machine sequence paths that can improve product quality. To validate its efficacy, we apply the approach to the industry-like data, successfully pinpointing both the most and least favorable paths.
