and only one is needed for the dry berries. This leaves two available to process wet berries, which at the rate of 1,050 bbls./hr. only need one as well.

We assume that one dryer can only process either bulk or bagged berries and not both at the same time. That is, one dryer can process 150 bbls./hr. of bagged berries or 200 bbls./hr. of bulk berries. With three drying units this gives an output rate of 150, 200, 300, 400, 450, or 600 bbls./hr. If we use the figures from Table B in the case we can find that 81.7% of the berries are bulk and the remaining 18.3% berries are to be bagged. At the 1,050 bbls./hr. rate for 12 hours (12,600 bbls. total) this corresponds to 10,294.2 bbls. bulk and 2,305.8 bbls. bagged. We also know that the bagged berries can be picked up at any time during 24 hours and it is thus advantageous to process bulk berries first during the day and then process bagged berries after hours. We also assume that berries prepared for baggin may also be used for bulk. Using the aforementioned assumptions, we can see that with three dryers we can process the bulk berries at a rate of 600 bbls./hr. and then switch to processing bagged berries at a rate of 450 bbls./hr.

Using these rates we can find out how long trucks have to wait before they can empty their contents into a dumpster. When analyzing the waiting time of the trucks we assume 12 hours of continuous arrival and the dumpsters may be loaded at
