AVR supplies food for the vending machines at a university. As the machines are mistreated by the university students, management has to repair them. The machines break down at an average of three per hour and the breakdowns are distributed in a Poisson pattern. The time the machines are down costs the company $25/hr and each maintenance worker earns $4/hr. One worker can service the machines at a rate of five per hour, exponentially distributed; two workers working together can service at seven per hour, exponentially distributed; and a crew of three can service at eight per hour, exponentially distributed. How large should the crew size be for optimum cost?

- 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 $17 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 34 trucks per hour according to a negative exponential distribution. Full trucks arrive all day long (during the…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.

- A bank has 1 enquiries staff and six tellers. Customers enter the system and walk up to the enquires counter for the enquiries queue or they go to the tellers station where they join a single queue for the 6 tellers.The arrival rate at the enquiry counter, lambda 8 customers per hour and the service rate at the enquiry counter, Mu 6 minutes per customer. The arrival rate at the tellers’stations, lambda 10 clients per hour and the service rate at the tellerstations, Mu 4 minutes per client. Find the total time customers spend at the bankA crew of mechanics at the Highway Department garage repair vehicles that break down at an average of 3 vehicles every 12 minutes (approximately Poisson in nature). The mechanic crew can service an average of 3 vehicles every 10 minutes with a repair time distribution that approximates an exponential distribution. The crew cost is approximately $150 per hour. The cost associated with lost productivity from the breakdown is estimated at $50 per hour. Which is cheaper, the existing system with one service crew or a revised system with two service crews? Note that the average waiting time for adding the second crew is 0.01.Kitty Wonderland (KW) makes toys for cats. KW’s managers have recently learned that they can calculate the average waiting time for an order from the time an order is received and the time it is manufactured. They have asked for your help and have provided the following information. Expected number of orders for the product: 2,000 Manufacturing time per order: 4 hours Annual machine capacity in hours: 10,000 After learning about the average waiting time, KW’s managers are confused. They do not understand why, if annual machine capacity is greater than the average number of orders for the product, there would be any waiting time at all. Briefly answer the following questions Calculate the average waiting time per order. The managers have asked for your suggestions on what they can do to minimize or eliminate waiting time. How would you respond? Management is expecting sales to increase. Will average waiting time increase or decrease? Explain briefly.
