- An 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 explanationA 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:An early warning security fence has three major components each must perform in order for the system to perform. Their reliabilities are .4, .3, and .2. The system reliability is equal to:
- Selecting an appropriate strategy for software test could be crucial for the success of the whole business. Consider the following scenario. Five software components were re-released into the field during the last three months. Each shipment resulted in a certain component exhibiting a major defect, for a total of three defects. These defects had to be immediately fixed with a hot patches. Other four components did not manifest any failures. Now we are standing in front of the next customer release and trying to decide which component(s) should be tested most prior to release. Which one of the following two strategies is appropriate? Focus testing on the component that failed in every previous release, since defects are usually cluster together. Do not focus testing on the component that failed in previous releases, since, most likely, all defects have been already exhausted thereA recent engineering change at Sullivan Wrist Calculator places a backup component in each of the two least reliable transistorcircuits. The new circuits will look like the following: R2 R3 R4 R5 .90 .95 .98 .90 .99R1.90 .90 What is the reliability of the new system?A six-sigma green belt candidate finds P/T ratio of his gauge as 0.632. The gauge has no bias. He tried improving his gauge precision, but failed to do so. He plans to use averages of repeated measurements in his quality improvement project. How many repeated measurements does he need to make on a part to have a P/T ratio of 0.200 based on the measurement averages? Answer:
- Rick Wing, salesperson for Wave SolderingSystems, Inc. (WSSI), has provided you with a proposal forimproving the temperature control on your present machine.The machine uses a hot-air knife to cleanly remove excess solder from printed circuit boards; this is a great concept, butthe hot-air temperature control lacks reliability. According toWing, engineers at WSSI have improved the reliability of thecritical temperature controls. The new system still has the foursensitive integrated circuits controlling the temperature, butthe new machine has a backup for each. The four integratedcircuits have reliabilities of .90, .92, .94, and .96. The fourbackup circuits all have a reliability of .90.a) What is the reliability of the new temperature controller?b) If you pay a premium, Wing says he can improve all fourof the backup units to .93. What is the reliability of thisoption?The guidance system of a ship is controlled by a computer that has three major modules. In order for the computer to function properly, all three modules must function. Two of the modules have reliabilities of .97, and the other has a reliability of .99.Which errors manifest most often during performance testing?

What is the reliability of this option?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.
