Concept explainers
a)
To determine: The percentage of scanners that are expected to fail.
Introduction:
Mean time between failures (MTBF):
The mean time between failures is a term which denotes the time that is elapsed between the first failure of a product and the second failure of a product. It is calculated during the normal system operation.

EBK OPERATIONS MANAGEMENT
- day, a FedEx competitor processes approximately 70,000 shipments. Suppose that they use the same Service Quality Index as FedEx and identified the following numbers of errors during a five-day week (see the “FedEx: Measuring Service Performance” box): These values are hypothetical and do not reflect any real company’s actual performance. Complaints reopened: 125 Damaged packages: 18 International: 102 Invoice adjustments: 282 Late pickup stops: 209 Lost packages: 2 Missed proof of delivery: 26 Right date late: 751 Traces: 115 Wrong day late: 15 Compute the Service Quality Indicator by finding the weighted sum of errors as a percentage of total shipments.arrow_forwardThe mean repair time of a reproduction machine every time it becomes defective is 5 hours, and is assumed to be available 95% of the time. What is its mean time between failure (MTBF)?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_forward
- Reliability metrics includes: Select one: a. Probability of failure on demand, Rate of occurrence of failures/Mean time to failure, and Availability b. Probability of failure on demand c. Availability d. Rate of occurrence of failures/Mean time to failurearrow_forwardCan you answer this question?arrow_forwardThe 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_forward
- Please Answer Quality Management Question A milling machine has an expected life of 10 years from the time it is installed into a production line. Assume the exponential distribution is appropriate. What is the probability that the machine will fail between 5 and 12 years after being installed into the production line? Suppose the three milling machines were designed in parallel into the production line system. What is the probability that the production line system will survive 10 years?arrow_forwardThe output from a process contains a 0.02 defective unit. Defective units that go undetected into final assemblies cost $25 each to replace. An inspection process, which would detect and remove all defectives, can be established to test these units. However, the inspector, who can test 20 units per hour, is paid $8 per hour, including fringe benefits. Should an inspection station be established to test all units?a. What is the cost to inspect each unit?b. What is the benefit (or loss) from the inspection process?arrow_forwardAn operation consists of two steps , the first of which has a reliability of 97% and the second a reliability of 99%. What is the probability that the operation will fail? please I need full explanationarrow_forward
- Output from a process contains 0.01 proportion of defective units. Defective units that go undetected into final assemblies cost $26 each to replace. An inspection process, which would detect and remove all defectives, can be established to test these units. The inspector, who can test 21 units per hour (which matches the current production rate), would be paid $9 per hour, including fringe benefits. Assume that the line will operate at the same rate (i.e., the current production rate) regardless of whether or not the inspection operation is added. A. Without the inspector, what is the current hourly cost of defects? (Round your answer to 2 decimal places.) B. If the inspection operation is added, what would be the cost to inspect each unit? (Round your answer to 2 decimal places.) C. What would be the benefit (or loss) from establishing the inspection process per unit? (Input the amount as a positive value. Round your answer to 2 decimal places.)arrow_forwardIf the manufacturer offers service contracts of Six years on these picture tubes, what percentage can be expected to fail from wear-out during the service period?arrow_forwardA garage door opener has three sections, which have reliabilities of .9, .8, and .9. The lowest of these has an identical backup that automatically goes on if the original fails. All three parts must operate to perform its intended function. The system reliability is closest to:arrow_forward
