| [en] We call attention to delivery chain systems as an area for statistical process control
research and propose using elapsed time variables as delivery-quality measures. We propose a Shewhart-style control charting strategy that we term ‘bundling’ which describes creating and averaging related time variables to allow for a reduction in the number of charts needed for monitoring delivery chain systems. The major assumption is that several related delivery chain system time-variables (DCSTV) representing origin to destination pairs that deliver products to a common geographical region would shift together when being monitored for delay. In the context of strategic monitoring of aggregate systems, bundled charts can effectively signal when origin-destination pairs shift in a particular direction. Given that some of the DCSTV can be ‘bundled’ for representation on Shewhart charts, decision makers can be provided an accurate assessment of the predictability (or unpredictability) of a delivery chain. Providing more accurate promises of delivery time through the use of Shewhart-style charts will ultimately reduce levels of safety stock which results in a reduction in inventory holding costs. | |
