Chapter B, Problem 13P
Summary Introduction
Interpretation: Whether the manager should hire any new personnel and the recommendations to the manager are to be concluded.
Concept Introduction: Poisson distribution is the tool helps to calculate the probability of happening in fixed period of time. Exponential distribution is the expected value of time elapsed between the two events.

Failsafe Textiles employs three highly skilled maintenanceworkers who are responsible for repairing the numerous in-dustrial robots used in its manufacturing process. A workercan fix one robot every 8 hours on average, with an exponen-tial distribution. An average of one robot fails every 3 hours,according to a Poisson distribution. Each down robot coststhe company $100.00 per hour in lost production. A newmaintenance worker costs the company $80.00 per hour insalary, benefits, and equipment. Should the manager hireany new personnel? If so, how many people? What would yourecommend to the manager, based on your analysis?

- Blue Lotus is a bike shop located near a beach resort, which rents its bikes to guests staying in the resort. When a customer requests to rent a bike and no bikes are available (they are either with another customers or being cleaned for rental), customer waits until a bike is available. Once a bike rented out to a customer, the customer keeps it for an average of 1 day. Upon return, the bike is cleaned and tuned-up, which takes half a day (0.5 day). Suppose Blue Lotus has 7 bikes, and demand for bike rental is 4.1 per day. What is the average amount of time a customer waits to receive a bike? (Hint: From the perspective of customer waiting time, 0.5 day of cleaning time would be part of the processing time" so, p = 1+0.5 =1.5 days. Assume CVa = CVp = 1 in your calculations).

A used cleaning vehicle will cost $85,000 and have a $20,000 market (salvage) value at the end of its five-year life. A new system with advanced features will cost $150,000 and have a $40,000 market value at the end of its five-year life. The new system is expected to reduce labor hours compared with the used system. Current street-cleaning activity requires the used system to operate 8 hours per day for 20 days per month. Labor costs $50 per hour (including fringe benefits), and MARR is 12% per year.]arrow_forwardPerformance Evaluation and Risk Aversion Jill Lewis is the office manager of PureBreds Inc.Her office has 30 employees whose collective job is to process applications by dog owners whowant to register their pets with the firm. There is never a shortage of applications waiting to be processed, but random events beyond Lewis’s control (e.g., employees out sick) cause fluctuations inthe number of applications that her office can process. Jill is aware that it is important that the applications be processed quickly and accurately. Alex Zale, the district manager to whom Jill reports,bases his evaluation of Jill on the number of applications that are processed.Required1. If Jill is risk averse, how should Alex compensate her? Why?a. Flat salary.b. Straight commission based on the number of applications processed.c. Flat salary with a bonus based on the number of applications processed.d.

When taking off, the run time of an airplane on the runway is 33 seconds. Planes are on average waiting 6 minutes and 48 seconds for takeoff. On average there are 16 planes taking off per hour. How many planes are either on the runway or waiting to take off?

A bureaucrat in Raleigh has determined the cost associated with lost productivity due to breakdowns is $300/day. This same bureaucrat thinks it would be a good idea to have two repair crews instead of one. Vehicles still break down at the same rate of 4/day. Each crew can still service 5 /day. Assume that each crew handles half of the breakdowns. Each crew costs $400/day. The cost associated with the lost productivity of an idle vehicle is still $300/day. What is the cost of waiting for this new system?arrow_forward

What is the cost of service for this new system?arrow_forwardA crew of mechanics at the Highway Department Garage repair vehicles that break down at an average of λ = 8 vehicles per day (approximately Poisson in nature). The mechanic crew can service an average of μ = 11 vehicles per day with a repair time distribution that approximates an exponential distribution. The crew cost is approximately $300 per day. The cost associated with lost productivity from the breakdown is estimated at $150 per vehicle per day (or any fraction thereof). What is the probability that there are more than two vehicles in the system?arrow_forwardA large food-processing corporation is considering using laser technology to speed up and eliminate waste in the potato-peeling process. To implement the system, the company anticipates needing $3 million to purchase the industrial-strength lasers. The system will save $1,200,000 per year in labor and materials. However, it will incur an additional operating and maintenance cost of $250,000 per year. Annual income taxes will also increase by $150,000. The system is expected to have a 10-year service life and a salvage value of about $200,000. If the company's MARR is 18%,justify the economics of the project using the PW method.arrow_forward
- In a company two mechanics maintain two very important machines in a production process, which usually break down on average every 16 hours. This time between breakdowns has an exponential distribution. A mechanic spends on average 10 hours repairing a machine (time with exponential distribution). Determine how much time a machine spends on average in the system.arrow_forwardA 10 station automated assembly system produces an ideal cycle time (Tc) of 14 seconds/cycle. When a defective part enters any assembly station it sometimes causes a station jam or stoppage. Defective parts occur at a rate of 0.07 and a jams due to defective parts occur at a rate of 0.4. When a jam occurs, it takes on average 74 seconds to clear and restart the station. Determine the production rate of acceptable parts (Rap) to the nearest 1 part/hour.arrow_forwardDuring a plant start-up, the operators should go through the start up sequence quickly to reduce the downtime and increase the profitability of the plant. there should be as few operators as possible near the column to ensure that any major accidents will result in lower injuries and fatalities. the operators should fully depend on the automated start up sequence without any intervention to increase the smoothness of the start up. Othere should be as many operators as possible near the column to ensure that any operational emergencies can be safely and quickly managed.arrow_forward
