Quality Analysis in Serial Production Line with Repairs: A Markov Chain Approach

摘要

In this paper, we present a quality flow model to analyze product quality in serial production lines with 100% inspections and repairs. Specifically, the serial production line consists of multiple inspection stations. After each inspection, defective parts will be repaired and sent back to the line. Two Markov chain models are introduced to analyze quality propagations along the serial production line. Analytical expressions of final product quality are derived and structural properties are investigated.
