Question
••• D.12 The wheat harvesting season in the American Midwest is short, and farmers deliver their truckloads of wheat to a giant central storage bin within a 2-week span. Because of this, wheat-filled trucks waiting to unload and return to the fields have been known to back up for a block at the receiving bin. The central bin is owned cooperatively, and it is to every farmer’s benefit to make the unloading/storage process as efficient as possible. The cost of grain deterioration caused by unloading delays and the cost of truck rental and idle driver time are significant concerns to the cooperative members. Although farmers have difficulty quantifying crop damage, it is easy to assign a waiting and unloading cost for truck and driver of $18 per hour. During the 2-week harvest season, the storage bin is open and operated 16 hours per day, 7 days per week, and can unload 35 trucks per hour according to an exponential distribution. Full trucks arrive all day long (during the hours the bin is open) at a rate of about 30 per hour, following a Poisson pattern. To help the cooperative get a handle on the problem of lost time while trucks are waiting in line or unloading at the bin, find the following:
- a. The average number of trucks in the unloading system
- b. The average time per truck in the system
- c. The utilization rate for the bin area
- d. The probability that there are more than three trucks in the system at any given time
- e. The total daily cost to the farmers of having their trucks tied up in the unloading process
- f. As mentioned, the cooperative uses the storage bin heavily only 2 weeks per year. Farmers estimate that enlarging the bin would cut unloading costs by 50% next year. It will cost $9,000 to do so during the off-season. Would it be worth the expense to enlarge the storage area?

During discussions with the Police to deal with the turbulence, the Police suggested that a mobile patrol would be adequate because the disorder was largely contained. However, the CEO of Paria insisted on permanent police presence. The CEO then offered to compensate the Police, if they agreed on a permanent on site presence during the turmoil. The Police thereafter indicated that they will provide 10 officers at a rate of $5000 per day, which they will maintain during the entire strike period. A few weeks after the strike was over, the Commissioner of Police, sent an invoice to Paria Oil Company for the cost of protection for two months. However, Paria Oil refused to compensate, and argued that the Police have a duty under law to protect the company from any pending violence and lawlessness.

An American distributor stops by every six weeks to take orders. Because the orders are shipped directly from Italy, they take five weeks to arrive. Charlie's Pizza uses an average of 160 pounds of pepperoni each week, with a standard deviation of 26 pounds. Charlie's prides itself on offering only the best-quality ingredients and a high level of service, so it wants to ensure a 99 percent probability of not stocking out on pepperoni.
