Question: An integrated-level capacity analysis will be performed on a new warehouse. The warehouse is serviced by a crane. Incoming parts are placed on the conveyor-1
An integrated-level capacity analysis will be performed on a new warehouse. The warehouse is serviced by a crane. Incoming parts are placed on the conveyor-1 (accumulating-accumulating) system (40 feet long, 30 feet/min, 3 feet space requirement per piece) and must gain access to the crane before exiting conveyor-1. Crane also serves shipment orders that have a higher priority than incoming parts. For a shipping order, the crane pulls the part from the warehouse and requires it to be placed on the non-accumulating conveyor-2 (50 feet long, 30 feet/min, 3 feet space requirement per piece). At the end of Conveyor-2 there are three operators for packing the parts. Packed parts are removed from the system. Introducing tracks arrive in a uniform distribution 24 hours a day (minimum 9 minutes and maximum 15 minutes). The average time required for the crane to store or pull a part from storage fits the triangular distribution (minimum 2 min, peak 3 min, and maximum 5 min). Shipment orders are released every 4 minutes for only 7 hours of the day. Packing time for an operator follows a normal distribution with a mean of 6 minutes and a standard deviation of 1.5 minutes. Operators are only on the first shift of the day but must wait until all shipping orders are completed. A 5-day operation of the system will be simulated. At the start of the simulation, 75 items will be loaded into the warehouse. The average inventory level across the entire warehouse will be reported. In addition, the area occupied on each conveyor and the crane utilization rate will be reported. Packaging operators will work during the first 8 hours of the day; therefore, the occupancy rates will be made over this 8-hour period.
