You are asked to assess the current service model for a manufacturing line featuring 8 machines. Based on empirical data you have determined that machines have a 20% likelihood of being down and in need of repair. There are currently 2 workers capable of running and repairing machines. Each of the 8 machines can produce 18 units/hour. The overhead for running each of the 8 machines is $700 per day per machine. Each operator is paid at an hourly rate of $16. [You can assume an 8-hour work day] a. Determine the total amount of lost work time. b. Should you hire an additional worker to run the 8 machines in this manufacturing line?

A mechanic at the Department of Maintenance makes minor repairs to faulty golf electric carts. The carts break down at an average rate of 4 carts per day and breakdowns are distributed according to the Poisson distribution. The mechanic can service an average of 6 carts per day with a repair time distribution that approximates a negative exponential distribution. Assume an 8 hour day. a- What is the utilization rate for the mechanic? b- What is the average time in hours that a cart is out of service?
A cashier at a supermarket is able to deal with on average, 480 customers per 8 hour shift. Calculate the service rate?
A copier is able to operate for an average of 200 hours between repairs, and the mean repair time is two hours. Determine the availability of the copier.
This problem illustrates balking. The Oryo Cookie IceCream Shop in Dunkirk Square has three competitors. Sincepeople don’t like to wait in long lines for ice cream, thearrival rate to the Oryo Cookie Ice Cream Shop depends onthe number of people in the shop. More specifically, whilej 4 customers are present in the Oryo shop, customersarrive at a rate of (20 5j) customers per hour. If more than4 people are in the Oryo shop, the arrival rate is zero. Foreach customer, revenues less raw material costs are 50¢.Each server is paid $3 per hour. A server can serve anaverage of 10 customers per hour. To maximize expectedprofits (revenues less raw material and labor costs), howmany servers should Oryo hire? Assume that interarrivaland service times are exponential.
A Company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 7 workers, who produced an average of 87 carts per hour. Workers receive $15 per hour, and machine coast was $43 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $14 per hour while output increased by four carts per hour. a) Compute the multifactor productivity (MFP) (labor plus equipment) under the Prior to buying the new equipment. The MFP (carts/S) = Blank 1 (round to 4 decimal places). b) Compute the productivity changes between the Prior to and after buying the new equipment. The productivity growth = Blank 2% (round to 2 decimal places) Blank 1 Add your answer Blank 2 Add your answer
2. A repair and inspection facility consists of two stations: a repair station with two technicians, and an inspector station with 1 inspector. Each repair technician works at the rate of 3 items per hour; the inspector can inspect 8 items per hour. Approximately 10% of all items fail inspection and are sent back to the repair station. (This percentage holds even for items that have been repaired two or more times.) If items arrive at the rate of 5 per hour, what is the long-run expected delay that items experience at each of the two stations, assuming a Poisson arrival process and exponentially distributed service times? What is the maximum arrival rate that the system can handle without adding personnel?

Prior to buying the new equipment, the company used 4 workers, who produced an average of 87 carts per hour. Workers receive $13 per hour, and machine coast was $32 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $18 per hour while output increased by four carts per hour.a) Compute the multifactor productivity (MFP) (labor plus equipment) under the Prior to buying the new equipment. The MFP (carts/$) = ( ) (round to 4 decimal places).b) Compute the % growth in productivity between the Prior to and after buying the new equipment. The growth in productivity = ( ) % (round to 2 decimal places)

1) An operator is used for loading and unloading of parts to automated machines. Loading time is 1 minute; unloading time is 2 minutes, machining time is 30 minutes, Operator travel time between the machines including the inspection time is 4 minutes. Cost of operator is C₁=40 TL/Hour, cost of a machine is C₂-200 TL/Hour. What is the cost per unit of production if optimum number of machines is assigned to the operator? (Note: Times are given in minutes and costs are per hour) a) 231 TL/unit b) 6930 TL/unit c) 115.5 TL/unit d) 240 TL/unit e) 132 TL/unit 2) An operator is used for loading and unloading of parts to automated machines.
