The Bubba Chump Shrimp Company processes and packages shrimp for sale to wholesale seafood distributors. The shrimp are transported to the main plant by trucks that carry 1,000 pounds (lb) of shrimp. Once the continuous flow process- ing of the shrimp begins, no inventory is allowed in buffers due to spoilage and all of the shrimp must be processed within 12 hours to prevent spoilage. The processing begins at the sorter, where the trucks dump the shrimp onto a conveyor belt that feeds into the sorter, which can sort up to 500 lb per hour. The shrimp then proceed to the desheller, which can process shrimp at the rate of 400 lb per hour. However, after 3 hours and 45 minutes of processing, the desheller must be stopped for 15 minutes to clean out empty shrimp shells that have accumulated. The veins of the shrimp are then removed in the deveining area at a maximum rate of 360 lb per hour. The shrimp proceed to the washing area, where they are processed at 750 lb per hour. Finally, the shrimp are packaged and frozen.
Note: All unit weights given are in "final processed shrimp." You do not need to account for the weight of the waste in the deshelling area. The plant operates continuously for 12 hours per day beginning at 8:00 a.m. Finally, there is negligible time to fill the sys- tem in the morning.
a. What is the daily process capacity of the desheller (in isolation from the other processes)?
b. What is the daily process capacity of the deveiner (in isolation from the other processes)?
c. What is the daily process capacity of the processing plant (excluding the packaging and freezing)?
d. If five trucks arrive one morning at 8:00 a.m., what is the total number of pounds of shrimp that must be wasted?
