- A typical retail transaction consists of several smaller steps, which can be considered components subject to failure. A list of such components might include: Let the eight probabilities of success be .92, .94, .99, .99, .98, .97,.95, and .96. What is the reliability of the system; that is, the probabilitythat there will be a satisfied customer? If you were the storemanager, what do you think should be an acceptable value forthis probability? Which components would be good candidatesfor backup, which for redesign?Assume that a computer has two 1TB disks, D0 and D1. The Mean Time to Failure (MTTF) ofeach disk is 1M hours.a. If the disk system is configured to have 2TB total storage capacity, when any of the two disksfails, the disk system fails. What is the MTTF of the disk system?b. Mirroring (RAID-1) is a technique can improve the reliability of disk systems by usingredundancy. Each data block will have two identical copies stored in both D0 and D1. Under thisconfiguration, the disk system has only 1TB total storage capacity; but it only fails when bothdisks fail (e.g. when the failed disk is being repaired, the second disk also fails). If the MTTR of afailed disk is 20 hours, what is the MTTF of the disk system now?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. The modules have reliabilities of 97%, 95%, and 99%. What is the reliability of the computer? A backup computer identical to the one being used will be installed to improve overall reliability. Assuming the new computer automatically functions if the main one fails, determine the resulting reliability. If the backup computer must be activated by a switch in the event that the first computer fails, and the switch has a reliability of 98%, what is the overall reliability of the system? Both the switch and the backup computer must function in order for the backup to take over.

What is the reliability of the system; thatis, the probability that there will be a satisfied customer? Ifyou were the store manager, what do you think should bean acceptable value for this probability? Which componentswould be good candidates for backup, which for redesign?One of the industrial robots designed by a leading producer of servomechanisms has four major components. Components’ reliabilities are .98, .95, .94, and .90. All of the components must function in order for the robot to operate effectively.a. Compute the reliability of the robot.b. Designers want to improve the reliability by adding a backup component. Due to space limitations, only one backup can be added. The backup for any component will have the same reliability as the unit for which it is the backup. Which component should get the backup in orderto achieve the highest reliability?c. If one backup with a reliability of .92 can be added to any one of the main components, which component should get it to obtain the highest overall reliability?Risks are prioritized based on the application of assessment criteria , and consideration of the organization's risk appetite . Select one: True False
- An office security system at PAC Ltd has two component parts, both of which must work for the system to function. Part 1 has a reliability of 80 percent, and part 2 has a reliability of 98 percent. Compute the reliability of the system.Company A has successfully launched its product in the market and has reaped rich dividends for the same. S is a top executive of the firm who is planning to move out to start the same business supported by a few investors. 6 months later, despite the product launch S has not been able to replicate the same success as in company A. Which of the following is a possible reason?The risks that the consequences of them are acceptable and no extra costs should be incurred to reduce hazard probability are categorized as: Select one: a. Intolerable b. Intolerable, Acceptable, and As low as reasonably practical (ALARP) c. As low as reasonably practical(ALARP) d. Acceptable
- 50-Step Assembly Line Consider an assembly line with 50 steps that are carried out sequentially. Each of the 50 steps has a defect probability of 1%. The final product produced on the assembly line is defective if any one of the 50 steps made a defect. At the end of the assembly line there are two operators independently inspecting the product. Each of them is recognizing a defective product with a 90% probability. Assuming that the product is not defective, it is moved to the shipping department. Otherwise, the product is scrapped. Probability that a defective product is produced (independent of the defect being found or not) (in decimal form): What is the probability that a defective product is moved to the shipping department?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:A product design engineer must decide if a redundant component is cost justified in a certain system. The system in question has a critical component with a probability of 0.96 of operating. System failure would involve a cost of GH¢20,000. What is the probability that the system will fail? Probability of the system failing is Blank 1. Fill in the blank, read surrounding text.
