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 submitted this question a couple days ago. However, I am still a little confused. Here was the original question: Collins Little Company has a staff of 4 employees, each working 8 hours per day at a rate of $20/hour. Their overhead expenses are $200/day. Collins processes and closes on 12 titles each day. They are considering purchasing a computerized title search system that will allow the processing of 20 titles per day. With the new system, they could cut their staff to 2 employees working the same hours at the same pay, but their overhead expenses would double to $400 per day. 1. Compute the labor productivity with the old system (in titles / hour). 2. Compute the labor productivity with the new system (in titles / hour). 3. Compute the multifactor productivity with the old system (in titles / dollar). 4. Compute the multifactor productivity with the new system (in titles / dollar). One of the answers is: Labor Productivity = 12/(4*8) Another is: Labor Productivity =…
A 3 year-old a computer-controlled fabric cutting machine, which had a $25,000 purchasing price, has a current market (trade-in) value of $10,000 and expected O&M costs of $4,000, increasing by 1,000 per year. The machine is required to have an immediate repair that costs $2,000. The estimated market values are expected to decline by 20% annually (going forward). The machine can be used for another 7 years at most. The new machine has a $40,000 purchasing price. The new machine's O&M cost is estimated to be $4,000 for the first year, decreasing at an annual rate of $100 thereafter. The firm's MARR is 10%. Assume a unique minimum AEC(10%) for both machines (both the current and replacement machine). Using the information above, determine the economic service life along with the optimum annual equivalent cost of the defender (This is an infinite Horizon decision problem). a) n=4 and AEC=Between $8,400 and $8,800 b) n=4 and AEC=Between $8,000 and $8,400 c) n=5 and AEC=Between $8,400 and…
. 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 142 hours and a projected average repair time of 7 hours. Projected times for machine B are an average operating time of 65 hours and a repair time of 2 hours. What are the projected availabilities of each machine?
1. Calculate the average customer arrival rate and service rate per hour. 2. Calculate the probability of zero patients in the system (P0), probability of one patient (P1), and probability of two or more patients simultaneously arriving during the night shift. 3. Using a criterion that if the probability is greater than 1 percent, a backup OR team should be employed, make a recommendation to hospital administration. I'm not sure how to find the answers to the empty boxes.

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 2 minutes. The average traveling time (a round trip) is 20 minutes. How many Avis buses are traveling to and from the airport? The branch manager wants to improve the service and suggests dispatching buses every 0.5 minute. She argues that this will reduce the average traveling time (a round trip) to Avis’s offices to 2.5 minutes. Is she correct? If your answer is negative, then what will the average traveling time be?
Planning service capacity involves consideration of the mean arrival rate and the mean service rate. When the mean arrival rate exceeds or gets too close to the mean service rate the quality of the service declines. The operating point is the ratio of mean service rate to mean arrival rate. According to the text, what is the best operating point for the typical service operation? O 120% 100% 90% 70%
Jobs arrive randomly at a particular assembly plant; assume that the arrival rate is five jobs per hour. Service times (in minutes per job) do not follow the exponential probability distribution. Two proposed designs for the plant’s assembly operation are shown: SERVICE TIME SERVICE TIME DESIGN MEAN STANDARD DEVIATION A 5.5 2.75 B 4 0.6 A.What is the service rate in jobs per hour for each design?b. For the service rates in part (a), what design appears to provide the best oR fastest service rate?c. Use the M/G/1 model to compute the operating characteristics for each design.i. The average number of customers in the waiting lineii. The average number of customers in the system.iii. The average time a customer spends in the waiting line (in hours)
In a job shop, effective capacity is only 43 percent of design capacity, and actual output is 71 percent of effective output. What design capacity would be needed to achieve an actual output of 11 jobs per week? What is its effective capacity?a. The Design Capacity needed to achieve the required actual job outputs = (round to whole number)b. The Effective Capacity needed to achieve the required actual job outputs = (round to whole number)
