An Exploratory Study on Stopping a Paced Line When Incompletions Occur

Abstract

This is an exploratory study of “hybrid” lines, i.e., “paced” lines whose cycle time can be extended (something like an “unpaced” line) when some task incompletions occur. Such a line should have its tasks classified into two categories; only the tasks in the first category have sufficiently high incompletion costs to justify extending the cycle time to ensure their completion. A heuristic procedure is developed to perform this classification, and we found that such hybrid lines may have a lower total cost (i.e. sum of labor and incompletion costs) than standard paced lines.
