Evaluating Lead Time Standard Deviation with Regard to the Lead Time Syndrome

摘要

Extending lead time standard deviation is a key figure that directly influences the due date reliability of a production process. Extending or reducing the planned lead time when trying to improve the due date reliability, does not only change the mean lead time, but also strongly affects the value of the lead time standard deviation. This connection is also associated with the Lead Time Syndrome of production control, which serves as a discussion framework. The aim of this paper is to investigate the lead time standard deviation influencing variables. As a result, various triggers of standard deviation will be discussed.
