A producer of pocket calculators estimates that the calculators fail at a rate of one every five years. The calculators are sold for $25 each with a one-year free replacement warranty but can be purchased from an unregistered mail-order source for $18.50 without the warranty.
What length of period of the warranty equates the replacement costs of the calculator with and without the warranty?
a bread manufacturer relies on maintenance employees to keep its rather quite old production equipment for their operation. Whenever the equipment breaks down, the maintenance team is able to repair the equipment quickly. However, they are less effective at avoiding these breakdowns and cannot predict when the equipment will break down. The maintenance group has modified the equipment over the years and, in any event, the manufacturer of the equipment is no longer in business. The maintenance employees teach each other how to repair the equipment, but have refused to document any of this information (saying that it is too difficult to document these details). The company owner has thought about firing the maintenance staff unless they document the maintenance procedures, but realizes that there is no one else who can repair the equipment. Discuss or explain the sources or types of power and contingencies (moderator) of power among the maintenance employees in this situation.

Assume that there is a
9%
rate of disk drive failure in a year.
a. If all your computer data is stored on a hard disk drive with a copy stored on a second hard disk drive, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
b. If copies of all your computer data are stored on
three
independent hard disk drives, what is the probability that during a year, you can avoid catastrophe with at least one working drive?
a. With two hard disk drives, the probability that catastrophe can be avoided is
nothing.
(Round to four decimal places as needed.)

- A department store sells a television set that was a one-year warranty (quality-assurance) that covers any product defects. When customers purchase a TV set, they also have the option to purchase an extended three-year warranty that covers any breakage or maintenance. The extended warranty sells for the same amount regardless of whether it is purchased at the same time as the TV set or at some other time. What is the only performance obligation of the department store ?arrow_forwardThree (3) computers together provide a replicated service. The manufacturers claim that each computer has a mean time between failure of five days; a failure typically takes four hours to fix. What is the availability of the replicated service?arrow_forwardTopford supplies X-Data DVDs in lots of 50, and they have a reported defect rate of 0.5% so the probability of a disk being defective is 0.005. It follows that the probability of a disk being good is 0.995. What is the probability of getting at least one defective disk in a lot of 50?

- The warehouse management system (WMS) of RoyaTech's Delaware Valley warehouse tracks service level at the warehouse. A service level failure at the warehouse is an event where a customer's order could not be shipped out in full by the promised shipping time. RoyalTech's ordering system prevents customers from placing orders on products that are not in-stock at the warehouse. Therefore, we can make the statement that "the WMS is guaranteed to show 100% service level at the warehouse." Choose the most appropriate statement in response: O True, because orders will be placed only for products that are available. O False, because service level can never be 100%. O False, because resource constraint or human error may delay the shipping even though inventory is available in the system. O False, because WMS calculations are faulty.arrow_forwardA local military base maintains a variety of different equipment. One of these is a sensitive radardevice that signals incursion of enemy planes into American airspace. Breakdowns of the device occur completely at random at an average rate of three per year.

For a specific failure mode, the value for "Severity" is equal to 6, the value for "Occurrence" is equal to 4 and the value for "Detection" is equal to 6, respectively. If the policy of the company is to take a further action for all failure modes with a Risk Priority Number (RPN) greater than or equal to 144, what should the company do with the aforesaid failure mode: Revisit the specific failure mode and re-calculate the RPN. Take further action because the value for RPN is above the threshold imposed by the company. Take further action because the value for Severity is life-threatening. Take further action because the value for Detection is life-threatening. Take further action because the value for Occurrence is life-threatening. Take NO further action because the RPN is NOT above the threshold imposed by the company.arrow_forward
