In a manufacturing company at present, the pattern shop and themaintenance department are located in the same room. One largecounter is used by both maintenance personnel to get tools andparts and by sand molders that need various patterns for themolding operation. Peter and Bob, who work behind the counter, areable to service a total of 10 people per hour (or about 5 per houreach). On the average, 4 people from casting/maintenance and 3people from the molding/pattern department arrive at the counterper hour. People from the molding department and from casting deptarrive randomly, and to be served they form a single line. Pete andBob have always had a policy of first come, first served. This is apoisson arrival pattern exponential service time model. Because ofthe location of the pattern shop and casting department, it takesabout 6 minutes for a person from the casting/maintenancedepartment to walk to the counter, and it takes about 2 minute fora person to walk from the molding. Separating the maintenance shopfrom the pattern shop had a number of advantages. It would takepeople from their department only 2 minutes now to get to thedepartment counter. Using time and motion studies, George was alsoable to determine that improving the layout of the maintenancedepartment would allow Bob to serve 6 people from the maintenancedepartment per hour, and improving the layout of the patterndepartment would allow Pete to serve 7 people from the molding shopper hour. This would act as a single server system for both thedepartments separately. In the present system how much minutes arespent in casting ? Give only numeric answer
