The manager of a car wash must decide whether to have one or two wash lines. One line will mean a fixed cost of $6,000 a month, and two lines will mean a fixed cost of $10,500 a month. Each line would be able to process 15 cars an hour. Variable costs will be $3 per car, and revenue will be $5.95 per car. The manager projects an average demand of between 14 and 18 cars anhour. Would you recommend one or two lines? The car wash is open 300 hours a month.

Jefferson Company’s demand for its only product exceeds its manufacturing capacity. The company provided the following information for the machine whose limited capacity is prohibiting the company from producing and selling additional units.  Actual run time this week 6,106 minutes Machine time available per week 8,600 minutes Actual run rate this week 4.32 units per minute Ideal run rate 6.00 units per minute Defect-free output this week 11,315 units Total output this week (including defects) 15,500 units 1. Compute the utilization rate.2. Compute the efficiency rate. 3. Compute the quality rate. 4. Compute the overall equipment effectiveness (OEE).

Compute the capacity (i.e. processing rate) for each of the following scenarios. Convertyour answers to parts per hour.a. A four-station line with single-machine stations, where the average processing timesare 15, 20, 10 and 12 minutes, respectively.b. A three-station line where the number of machines at stations 1, 2 and 3 is 2, 6, and3, respectively; and the average processing times are 10, 24 and 18 minutes,respectively.

A manager must decide between two machines. The manager will take into account each machine's operating costs and initial costs, and its breakdown and repair times. Machine A has a projected average operating time of 140 hours and a projected average repair time of 7 hours. Projected times for machine B are an average operating time of 70 hours and a repair time of 6 hours. What are the projected availabilities of each machine? (Round your answer to 3 decimal places). I don't want the answer. I just want to know HOW to do it.

An MI MI3 system has an arrival rate of 11 customers per hour. Each server has a service rate of 8 customers per hour. a. What is the utilization factor for this system? (Round your answer to 3 decimal places.) Utilization factor b. If all servers are kept busy, how many services will be completed per hour? (Round your answer to the nearest whole number.) Services completed per hour Mc Graw Hill ASUS

The Avis Company is a car rental company and is located three miles from the Los Angeles airport (LAX). Avis is dispatching a bus from its offices to the airport every 3 minutes. The average traveling time (a round trip) is 27 minutes. a. How many Avis buses are traveling to and from the airport? Note: Round your answer to the nearest whole number. Number of Avis buses b. The branch manager wants to improve the service and suggests dispatching buses every 1.0 minute. She argues that this will reduce the average traveling time (a round trip) to 4.0 minutes. Is she correct? If your answer is negative, then what will the average traveling time be? average traveling time is minutes

In an M/M/1 queueing system, the arrival rate is 5 customers per hour and the service rate is 7 customers per hour. If the service process is automated (resulting in no variation in service times but the same service rate), what will be the resulting performance measurements? (Round all answers to three decimals.)  What is the utilization? What is the expected number of customers in the system (L)? What is the expected waiting time (in hours) for the system (W)? What is the expected number of customers in the queue (Lq)? What is the expected waiting time (in hours) in the queue (Wq)?

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?
