Chapter 12, Problem 41P
A manager is going to purchase new processing equipment and must decide on the number of spare parts to order with the new equipment. The spares cost $200 each, and any unused spares will have an expected salvage value of $50 each. The probability of usage can be described by this distribution:
If a part fails and a spare is not available, two days will be needed to obtain a replacement and install it. The cost for idle equipment is $500 per day. What quantity of spares should be ordered?
a. Use the ratio method.
b. Use the tabular method (see Table 13.3).

The Clark County Sheriff's Department schedules police officers for 8-hour shifts. The beginning times for the shifts are 8:00 a.m., noon, 4:00 p.m., 8:00 p.m., midnight, and 4:00 a.m. An officer beginning a shift at one of these times works for the next 8 hours. During
normal weekday operations, the number of officers needed varies depending on the time of day. The department staffing guidelines require the following minimum number of officers on duty:

The plant was located in an industrial area that had several pipelines in the general geographic area including a crude oil pipeline leading to a refinery, and a pipeline carrying pesticides to be processed and redistributed to local farms in the area. In July 2014, Ajay Patel, the logistics general manager received notification that there were some minor leaks along the pipeline that were being fixed. Workers in the area had experienced sudden headaches and lightheadedness and the company immediately moved to investigate the leak and address faulty seams that had eroded and weakened. The flow of naphtha was temporarily stopped for 72 hours so two portions of the pipeline could be removed, and the eroded portions replaced.
