OPNS D30 Operations Management National Cranberry Cooperative 1. Process flow diagram and bottleneck operations For the process flow diagram, see Exhibit 1. The bottleneck operation is Drying (rate: 600 bbls/hr). Let’s consider the wet and dry processing separately: * Wet processing: RP1 can dechaff up to 3,000 bbls/hr, but only dry 600 bbls/hr. Thus, the bottleneck operation of wet processing is drying, and the bottleneck rate is 600 bbls/hr. * Dry processing: RP1 can destone 4
