4.7. Glen Evans is an emergency medical technician for a local res-cue team and is routinely called on to render emergency care to cit-izens facing crisis situations. Although Glen has received extensivetraining, he also relies heavily on his equipment for support. Duringa normal call, Glen uses five essential pieces of equipment, whoseindividual reliabilities are 0.98, 0.97, 0.95, 0.96, and 0.99, respectively.a. Glen claims his equipment has maximum probability of fail-ure of 5%. Is he correct?b. What individual equipment reliabilities would guarantee anoverall reliability of 96%?

Problem 13-4 (Algo) There is a 3 percent error rate at a specific point in a production process. If an inspector is placed at this point, all the defects can be detected and eliminated. The inspector would cost $11 per hour and could inspect units in the process at the current production rate of 52 per hour. If no inspector is hired and defects are allowed to pass this point, there is a cost of $12 per defective unit to correct the defects later on. Assume that the line will operate at the same rate (i.e., the current production rate) regardless of whether the inspector is hired or not. a. If an inspector is hired, what will be the inspection cost per unit? (Round your answer to 3 decimal places.) Cost per unit b. If an inspector is not hired, what will be the defective cost per unit? (Round your answer to 3 decimal places.) Cost per unit

A lathe machine worked 10 hours on a shift for 150 days. During this period, 3 failures occurred. The maintenance operators spent 4 hours, 3.5 hours, and 6 hours respectively, to repair each of these failures. a) What is the Mean Time Between Failure (MTBF) for the lathe machine? b) What is the Mean Time to Repair (MTTR) for the lathe machine? c) What is the Failure Rate? d) What is System Availability?
Background: Data about the frequency of adverse events related to inappropriate care in hospitals come from studies of medical records as if they represented a true record of adverse events. In a prospective, observational design we analyzed discussion of adverse events during the care of all patients admitted to three units of a large, urban teaching hospital affiliated to a university medical school. Discussion took place during routine clinical meetings. We undertook the study to enhance understanding of the incidence and scope of adverse events as a basis for preventing themMethods: Ethnographers trained in qualitative observational research attended dayshift, weekday, regularly scheduled attending rounds, residents' work rounds, nursing shift changes, case conferences, and other scheduled meetings in three study units as well as various departmental and section meetings. They recorded all adverse events during patient care discussed at these meetings and developed a classification…

Cycle-Time Analysis Variability is often considered to be the enemy of efficient and effective management. One approach to managing cycle times to improve delivery dependability is to map out the associated activities in a value-added process using a process flow diagram (see diagram in problem þelow). This allows the manager to identify and measure the specific activities so that the management process can be made more effective. The following problem illustrates the use of cycle time analysis. Problem Company X has recently completed an analysis of its primary value-added process. As part of this analysis, the major flows have been mapped such that the process has been broken down into 10 major activities. To better understand the process, the times to complete,each of these activities have been carefully monitored over the past month. The results of this monitoring follow.

Case of Wrong Leg Amputation In one of the most tragic surgical errors, 52-year-old Willie King was supposed to have a diseased leg amputated in 1995. Instead, the surgeon took the wrong one off. As in many wrong site surgerycases, there were a series of mistakes that led to the wrong leg be ing amputated. The incorrect leg was listed in a number of key places including the blackboard in the operating room, the hospital's computer system, and the operating room schedule. The staff had sterilized and prepped the wrong leg for surgery before the surgeon, Dr. Rolando Sanchez, appeared in the operating room. The doctor's defence later was that both legs were unhealthy and would have to be amputated in any event. He was fined $10,000 and received a six-month medical license suspension. The cases against the surgeon and hospital were settled for $1.15 million. A. Define a 'negligent ac t' and state its elements. B. Use of res ipsa loquitur in medical malpractice cases appears to have had the…

A fleet repair center resets its computerized diagnostic system after every 15 trucks to help ensure there are limited major downtimes from system failure. The reset takes 22 minutes on average with a CV of 0.3. Each trucks diagnosis takes 28 minutes on average with a CV of 1.75 not considering the resets. 1. What is the effective process time and its CV? 2. If the reset system is not used, failures will occur after 57 hours on average with an average repair time of 3 hours. The CV of repair time is 0.9. What is the effective process time and its CV? Is the maintenance system beneficial if it prevents breakdowns? Just consider effective processing time parameters. 3. The maintenance program costs $10,000 annually. The average profit per car from the diagnostic service is $75. Assume the service center operates 250 days per year, 10 hours per day. Is the maintenance program economically beneficial? What assumptions are needed?

Each day, a FedEx competitor processes approximately 50,000 shipments. Suppose that they use the same Service Quality Index as FedEx and identified the following numbers of errors during a 5-day week (see the "FedEx: Measuring Service Performance" box). These values are hypothetical and do not reflect any real company’s actual performance. Description Weight Number of Errors Complaints reopened 3 145 Damaged packages 10 17 International 1 109 Invoice adjustments 1 284 Late pickup stops 3 207 Lost packages 10 4 Missed proof of delivery 1 28 Right date late 1 752 Traces 3 115 Wrong day late 5 11 Compute the Service Quality Indicator by finding the weighted sum of errors as a percentage of total shipments. Do not round intermediate calculations. Round your answer to three decimal places. Service Quality Indicator (SQI): %
