Article Abstract

[This abstract is based on the authors' abstract.] A multiple stream process is investigated in which only a fraction of the total streams can be monitored at a given time. This situation occurs when speed of production is great and includes a large number of streams, but the monitoring process is not fully automated. The adaptive fractional-sampling approach applied to the 52 stream filling operation in a beverage bottling facility is shown to give superior results to the fixed fraction scheme and provides great flexibility.
