- 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.A copier is able to operate for an average of 200 hours between repairs, and the mean repair time is two hours. Determine the availability of the copier.A manufacturer of microwaves has discovered that male shoppers, on average have lower values for microwave ovens than female shoppers. Additionally, male shoppers attribute almost no extra value to an auto-defrost feature, while female shoppers, on average, value the auto-defrost feature. The manufacturer has determined that men value a simple microwave at $70 and one with autodefrost at $80, while women value a simple microwave at $80 and one with auto-defrost at $150. If there is an equal number of men and women, what pricing strategy will yield the greatest revenue?
- A vendor is running a promotion whereby an end customer who purchases three boxes of golf balls at $20 per box in a single transaction receives an offer for one free box of golf balls if the customer fills out a request form and mails it to the vendor before a set expiration date (a mail-in rebate). The vendor estimates, based on recent experience with similar promotions, that 80% of the customers will complete the mail-in rebate required to receive the free box of golf balls. How should the consideration be allocated to the various deliverables in the arrangement?A worker at the State Unemployment Office isresponsible for processing a company’s forms when it opensfor business. The worker can process an average of 4 formsper week. In 2002, an average of 1.8 companies per weeksubmitted forms for processing, and the worker had abacklog of .45 week. In 2003, an average of 3.9 companiesper week submitted forms for processing, and the workerhad a 5-week backlog. The poor worker was fired and suedto get his job back. The court said that since the amount ofwork submitted to the worker had approximately doubled,the worker’s backlog should have also doubled. Since his backlog increased by more than a factor of 10, he must havebeen slacking off, so the state was justified in firing him.Use queuing theory to defend the worker (based on an actualcase!).A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used five workers, who produced an average of 80 carts per hour. Workers receive $10 per hour, and machine cost was $40 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $10 per hour, while output increased by four carts per hour.A) Compute labor productivity under each system. Use carts per worker per hour as themeasure of labor productivity.B) Compute the multifactor productivity under each system. Use carts per dollar cost (laborplus equipment) as the measure.C) Comment on the changes in productivity according to the two measures, and on which one you believe is the more pertinent for this situation.
- Imagine you are in line to enter a brand new shopping mall and you are very much excited because after months of waiting, you will now be able to enter shopping malls after the pandemic. The stores comprising the mall are very popular. These stores include Converse, Gucci, Jansport, Fendi and all other popular brands, and so the demand to enter is very high. Security guards only allow one person through the doors at a time. As a result, the line and the wait are quite long. To add to the chaos, the waiting crowd is made mostly of frequent shoppers who are growing very impatient and holding up the line with their constant complains. Together, these factors affect the flow of customers into the shopping mall, just as electric resistance affects the flow of charges through a current. 1. The type of customers (patient or impatient) the line is made up of will determine how orderly or chaotic the shopping mall is. Most wires are made up of what type of material and why? Name some examples…A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts.

If customers have installation or use problems with Ocala software products, they may telephone the technical support center and obtain free consultation. Currently, Ocala operates its support center with one consultant. If the consultant is busy when a new customer call arrives, the customer hears a recorded message stating that all consultants are currently busy with other customers. The customer is then asked to hold and is told that a consultant will provide assistance as soon as possible. The customer calls follow a Poisson probability distribution, with an arrival rate of six calls per hour. On average, it takes 7.1 minutes for a consultant to answer a customer's questions. The service time follows an exponential probability distribution. To improve customer service, Ocala Software Systems wants to investigate the effect of using a second consultant at its technical support center. (Round your…
