. The Newcoat Painting Company has for some time been experiencing high demand for its automobile repainting service. Because it has had to turn away business, management is concerned that the limited space available to store cars awaiting painting has cost them in lost revenue. A small vacant lot next to the painting facility has recently been made available for rental on a long-term basis at a cost of $10 per day. Management believes that each lost customer costs $20 in profit. Current demand is estimated to be 21 cars per day with exponential interarrival times (including those turned away), and the facility can service at an exponential rate of 24 cars per day. Cars are processed on a FCFS basis. Waiting space is now limited to 9 cars but can be increased to 20 cars with the lease of the vacant lot.Newcoat wants to determine whether the vacant lot should be leased. Management also wants to know the expected daily lost profit due to turning away customers if the lot is leased. Only…

The call centre operates eight hours a day (0900-1700) five days a week and is closed on weekends. Call volumes and demand fluctuate, but there is one noticeable peak period between mid October and January inclusive (15 weeks). Records show that the average call numbers during the off-peak period is 250 calls per day, whilst on peak days call numbers average 608 calls per day. The call centre is staffed by a team of 3 permanent staff members. Full time staff can handle up to a maximum of 12 calls per hour each and it has been shown that the full time staff can cope with all the calls during off-peak periods. Temporary staff are engaged for the peak period and, generally, can answer 8 calls per hour. Temporary staff, sourced from a local recruitment agency cost £76.75 per 8 hour day shift inclusive of all agency fees. A specialist IT company has proposed installing an enhanced call handling system which, it is claimed, will increase productivity enabling permanent staff to…
Charles Lackey operates a bakery in Idaho Falls, Idaho. Because of its excellent product and excellent location, demand has increased by 5555% in the last year. On far too many occasions, customers have not been able to purchase the bread of their choice. Because of the size of the store, no new ovens can be added. At a staff meeting, one employee suggested ways to load the ovens differently so that more loaves of bread can be baked at one time. This new process will require that the ovens be loaded by hand, requiring additional manpower. This is the only production change that will be made in order to meet the increased demand. The bakery currently makes 1,800 loaves per month. Employees are paid $8 per hour. In addition to the labor cost, Charles also has a constant utility cost per month of $800 and a per loaf ingredient cost of $0.35 Current multifactor productivity for 640 work hours per month =0.27loaves/dollar (round your response to three decimal places).

Winchester Hospital is a privately owned institution. The hospital is at full capacity, but the governing board would like to see an increase in revenue. They’ve tasked you, the hospital administrator, with finding ways to accomplish this. If you are able to raise revenue, the board will provide you with a significant year-end bonus. Currently, 50% of Winchester’s rooms can be converted from having one bed to having two beds, allowing for more patients to be admitted. Doctors, nurses, and other hospital staff are firmly against this move, especially because additional hiring is not planned. These stakeholders make up the vast majority of the hospital workforce. Evaluate this situation using both the utilitarianism and individualistic (ethical egoism) approaches. Define each approach and describe how each would resolve the decision. What would you expect the outcome of each decision to be? Support your conclusions with facts from the situation.
Ex 5 Fitzsimmons & Fitzsimmons (2008) compare 2 capacity management strategies. Part of their comparison is presented below: Capacity plan: Level Capacity Chase Demand Customer waiting Generally low Moderate High Long run Labour skill level Low Forecasting Short run a) Motivate why the forecasting horizon is longer for Level capacity plans. b) Which assumption is used to reach the conclusion that a level capacity plan has a shorter customer waiting time?
Thomas Pang Furniture produced 70,000 Executive chairs per week. The effective capacity is 71,000 chairs. The production line operates 5 days per week with two 6-hour shifts per day. The line was designed to process the Executive chairs at the rate of 1,200 per hour. Determine the design capacity, utilization and efficiency for this plant when producing the Executive chair. Thomas Pang Furniture now needs to increase production of the Executive chairs. A second production line will be added. Effective capacity on this second line is the same as the first line at 71,000 Executive chairs. The first line is operating at a higher efficiency but output on the second line will be no more than 75% because the crew will be primarily new hires. Determine the expected output of this second line.
