A service firm is willing to provide preventive maintenance under either of two options: #1 is $500 and covers all necessary repairs, and #2 is $350 and covers any repairs after the first one. Which option would have the lower expected cost: pay for all repairs, service option #1, or service option #2?

DuLarge Marine manufactures diesel engines for shrimp trawlers and other small commercial boats. One of their automated machines has caused several problems. Over the past 30 weeks, the machine has broken down as indicated below. Each time the machine breaks down, the firm loses an average of $3,000 in time and repair expenses. If preventive maintenance were implemented, it is estimated that an average of only one breakdown per week would occur. The cost of preventive maintenance is $1,000 per week.

For an additional fee, a customer purchasing a Whirlpool appliance, such as washing machine, can purchase a three year service contract. The contract provides free repair service and parts for the specified appliance using an authorized Whirlpool service provider. When a person with Whirlpool service contract needs to repair an appliance such as washing machine, he or she calls the whirlpool repairs and parts department to schedule an appointment. The department makes the appointment and gives the caller the date and approximate time of the appointment. This process is very lengthy. It may take two weeks to schedule a repair visit.In above case what changes could be made to make this process more efficient with the development of Information system. Discuss in detail various phases of System Development life cycle that are involved in this case.
Four regional less-than-truckload (LTL) carriers handle shipments traveling from Lexington, Kentucky, to Springfield, Illinois. All four companies say that their normal service time to deliver these shipments is two business days. The four carriers compete with each other on the basis of price and service quality rating, as shown in the following table. The price reported in the table is the (nondiscounted) cost per hundredweight (cwt) of sending a 600-pound shipment from Lexington to Springfield at freight class 70. The service quality rating measures a carrier’s loss and damage record and goes from 0 (poor quality) to 100 (high quality).

- At the beginning of each week, a machine is in one of four conditions: 1 = excellent; 2 = good; 3 = average; 4 = bad. The weekly revenue earned by a machine in state 1, 2, 3, or 4 is 100, 90, 50, or 10, respectively. After observing the condition of the machine at the beginning of the week, the company has the option, for a cost of 200, of instantaneously replacing the machine with an excellent machine. The quality of the machine deteriorates over time, as shown in the file P10 41.xlsx. Four maintenance policies are under consideration: Policy 1: Never replace a machine. Policy 2: Immediately replace a bad machine. Policy 3: Immediately replace a bad or average machine. Policy 4: Immediately replace a bad, average, or good machine. Simulate each of these policies for 50 weeks (using at least 250 iterations each) to determine the policy that maximizes expected weekly profit. Assume that the machine at the beginning of week 1 is excellent.arrow_forwardWill and Jason Najami are going to open a swimming pool service this summer. They will put in pools, repair damaged ones, and provide a pool cleaning service. They have decided to use a service guarantee as their primary service recovery tool. How can they make sure that their service guarantee is effective?arrow_forwardA plastic injection molding machine operates 334 days a year. It is the bottleneck workstation in a process that produces plastic housed wall clocks. Industrial engineers collected data on the probability of machine breakdowns, the costs of preventive maintenance, and the cost of a breakdown. Number of Molding Machine Breakdowns per Day Probability of a breakdown 0 0.32 1 0.27 2 0.22 3 0.13 4 0.06 The cost of preventive maintenance is high due to performing it between 1 and 4 a.m. each day by two machine experts. The preventive maintenance cost is $2,030 per day including replacement parts, cleaning, and software upgrades. The cost of a breakdown of $1,940 is also high because the downstream workstations can only work until all work-in-progress inventory is completed; then the entire process must stop.

- A crew of mechanics at the Department of Transportation garage make minor repairs to snowplows during the winter. The snowplows break down at an average rate of 5 vehicles per day and breakdowns are distributed according to the Poisson distribution. The mechanic can service an average of 8 vehicles per day with a repair time distribution that approximates a negative exponential distribution. Assume an 8 hour day. What are the chances that 3 vehicles are in the service system? Group of answer choices 9% 38% 63% 19%arrow_forwardobs arrive at Loaf Machine Shop. Assume the arrival rate is five jobs per hour.

In some circumstances, where AJAX is too busy and does not have capacity to fulfil deliveries or they do not cover certain areas, only then will Prybloxx make use of a different courier company. Prybloxx has recently had a significant influx of customer complaints regarding goods that have not been delivered, delivered long after the agreed delivery time or damaged once they arrive at the customer. Prybloxx is aware of the effect that this could have on demand for their product, customer goodwill and are now investigating insourcing the delivery of their product to customers. Prybloxx has noted that they have two alternatives in insourcing this department – they can either purchase a local courier company that is considered a going concern or they can purchase all of the required assets and set up such a department themselves.

The goal is to cut costs, reduce delivery-related accidents and cope with a labour shortage in one of the world’s fastestaging nations. Kim is confident that his Dilly robots will start deliveries within three years. Woowa Brothers Corp, the company behind Baedal Minjok, raised US$320mil fromHillhouse Capital, Sequoia Capital and GIC in the US to help develop a prototype that’s set to roll out soon.

- A city in Ohio is considering replacing its fleet of gasoline-powered automobiles with electric cars. The manufacturer of the electric cars claims that this municipality will experience significant cost savings over the life of the fleet if it chooses to pursue the conversion. If the manufacturer is correct, the city will save about $1.5 million dollars. If the new technology employed within the electric cars is faulty, as some critics suggest, the conversion to electric cars will cost the city $675,000. A third possibility is that less serious problems will arise and the city will break even with the conversion. A consultant hired by the city estimates that the probabilities of these three outcomes are 0.30, 0.30, and 0.40, respectively. The city has an opportunity to implement a pilot program that would indicate the potential cost or savings resulting from a switch to electric cars. The pilot program involves renting a small number of electric cars for three months and running them…arrow_forwardEastern Motors Auto Dealership wanted to estimate the average CLV over a 5 year time horizon of a customer who purchases a new vehicle. The average vehicle sells for $28,939 and has a margin of 6%. Based on historical averages, 83 of people buying a new vehicle at Eastern will return for service 9 times over the next 5 years. Though it varies considerably, Eastern generates approximately $92 in margin on each service visit after accounting for parts and direct labor costs. What is the estimated 5 year value of the service component (only) of a customer who purchases a new vehicle at Eastern Motors?arrow_forwardAn injection molding system has a first cost of $90,000, and an annual operating cost of $42,000 in year 1, increasing by $5000 per year thereafter. The salvage value of the system is 30,000 if you sell after 1 year of use. The salvage value decreases by $5,000 each year thereafter. The maximum useful life of the machine is 4 years. Using a MARR of 20% per year, determine the ESL and the corresponding Equivalent Annual Cost of the system.arrow_forward
