An analysis of line‐stop strategy in just‐in‐time manufacturing

In pursuit of zero‐defect quality, a growing number of JIT manufacturing firms often consider a line‐stop strategy that allows workers to stop the assembly line when abnormalities occur during production process, and to repair defects immediately as they occur. The line‐stop strategy contrasts with a traditional off‐line repair strategy that either scraps the defects or sends them to a separate repair station. Develops an expected total cost model to demonstrate the cost‐effectiveness of the line‐stop strategy over the off‐line repair strategy in JIT environments. Computational experiments indicate that cost savings resulting forum using the line‐stop strategy are greater than those using the off‐line repair strategy.
