With this system, it is estimated that 85 cars per hour can be serviced.

A manager must whether to buy machine A or B. Machine costs are as follows: A $52,000 each; B $100,000 each Product forecast and processing times on the machines are as follows Processing Time per unit (minutes) Product Annual Demand A B 1 8,000 2 18,000 3 10,000 Assume that only purchasing costs are being considered. Which machine would have the lowest purchase cost and how many of that machine would be need? Machines operate 8 hours a day 250 days per year. The machines differ in hourly operation costs. The A machines have an hourly operating cost of $12 each and B machines have an hourly operating cost of $30 each. What is the operating cost per year and which alternative should be selected to minimize total cost (for the first year) while satisfying the processing requirements?

A recurring maintenance job in a factory is being done by a three-man crew. Due to the nature of the job and space limitations, it was observed that two of the men were idle 37% of the time; one of the men was also idle an additional of the time, and at any given time only one man was required. The men were each paid P24.00 per hour. Each time the job was performed a set of tools and equipment with a value equivalent to P36.00 per hour was used. If the three-men crew could complete the work in 5 hours, which crew size would be the most economical

Four employees at a fast-food restaurant each perform one of the four activities in serving a customer: greet customer, take order, process order, and deliver order. The processing time for each activity is given as follows: Greet customer Take order Process order Deliver order A) 50% Assume demand is unlimited. What is the average labor utilization? B) 68% C) 40% Activity D) 162% Processing time per customer 2 seconds 30 seconds 60 seconds 5 seconds

Consider the flow in Figure 7–1 but assume that no patients require follow-upappointments. All patients first check in with the single receptionist, which takesan average of 6 minutes. They are then seen by one of two nurses who take weight,blood pressure, etc., which takes an average of 10 minutes. Finally, they are seenby a GP in an examination room, which takes an average of 16 minutes. There arethree GPs. The table below summarizes this data. Assume the clinic has no waitingroom or examination room constraints.Assume that there are eight patients arriving an hour during working hours.Resource Minutes per patient Number of resourcesReceptionist 6 1Nurse 10 2Doctor 16 3a. What is the capacity of each resource?b. Which resource is the bottleneck and hence what is the capacity of the system?

A work cell in a local manufacturer has a workstation with 4 machines that form a line (Machine 1-Machine 2-Machine 3-Machine 4). Each unit needs to pass through each machine in order to be completed. Each machine has a production capacity of four units per hour. What is the process time of the work cell in minutes per unit? 15 4 8 16

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 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)

Benny the Barber owns a one-chair shop. At barber college, they told Benny that his customers would exhibit a Poisson arrival distribution and that he would provide an exponential service distribution. His market survey data indicate that customers arrive at a rate of 4.0 per hour. It will take Benny an average of 8 minutes to give a haircut. Based on these figures, find the following: a. The average number of customers waiting. Note: Round your intermediate calculations to 3 decimal places and final answer to 2 decimal places. Average number of customers waiting b. The average time a customer waits. Note: Round your answer to 2 decimal places. Average waiting time minutes

A manager must decide which type of machine to buy, A, B, or C. Machine costs (per individual machine) are as follows: Machine Cost $50,000 A B $40,000 C $70,000 Product forecasts and processing times on the machines are as follows: PROCCESSING TIME PER UNIT (minutes) Annual Product Demand 1 2 3 4 18,000 25,000 15,000 9,000 A 1 5 4 5 A B C B Click here for the Excel Data File 6531 Total processing time in minutes per machine: a. Assume that only purchasing costs are being considered. Compute the total processing time required for each machine type to meet demand, how many of each machine type would be needed, and the resulting total purchasing cost for each machine type. The machines will operate 8 hours a day, 220 days a year. (Enter total processing times as whole numbers. Round up machine quantities to the next higher whole number. Compute total purchasing costs using these rounded machine quantities. Enter the resulting total purchasing cost as a whole number.) C 2 1 2 6

SkyChefs, Inc., prepares in-flight meals for a number of major airlines. One of the company’s products is grilled salmon in dill sauce with baby new potatoes and spring vegetables. During the most recent week, the company prepared 4,300 of these meals using 1,250 direct labor-hours. The company paid its direct labor workers a total of $11,250 for this work, or $9.00 per hour.   According to the standard cost card for this meal, it should require 0.30 direct labor-hours at a cost of $8.50 per hour.   Required: 1. What is the standard labor-hours allowed (SH) to prepare 4,300 meals?  2. What is the standard labor cost allowed (SH × SR) to prepare 4,300 meals? 3. What is the labor spending variance? 4. What is the labor rate variance and the labor efficiency variance?
