Concept explainers
a)
To determine: The decrease in the reliability of plan 1.
Introduction:
Reliability:
Reliability can be termed as the measure of the capability of a product or any service to perform its intended job under a predetermined set of conditions. The product or service will yield the same results on the repeated trials. It is the degree of consistency of a measure.

- A floor cleaning robot contains 4 modules that are critical to its operation. The modules and their individual reliabilities are listed below. Movement module 0.98 Data Storage Module 0.999 Learning Module 0.99 Vision Module 0.94 What is the probability that the system will be up and running? Suppose this number is too low and it is desired to improve the reliability through redundant elements. What would be the new reliability from each one of these changes? a. back up the Vision module with an identical module. b. back up the movement module with an identical module, but not the vision module.arrow_forwardExplain the concept of Mean Time Between Failures (MTBF) and its significance in system reliability.arrow_forwardDescribe the concept of Mean Time Between Failures (MTBF) and its significance in system reliability assessment.arrow_forward
- The ABC Bank processes loan applications through 3 clerks set up in series, with reliabilities of 0.90, 0.80, and 0.99. a. The bank manager decided to provide redundancy to the two least reliable clerks. Reliability measures of the redundants are equal to the corresponding primary clerk. What is the new system reliability? Show illustration and complete solution. b. What will be the system reliability if the bank replaces the clerk with reliability measure of 0.80 and his redundant, with a 90% reliable clerk? Show illustration and complete solution.arrow_forwardExplain the concept of system reliability and its significance in technology.arrow_forwardJ 2 A system consists of 3 components in series. The reliability of each component over the anticipated lifetime and its cost are given in the table below. You already have one component for each kind, you may purchase additional components and operate them in parallel (add redundancy) at each stage. Assume a budget of $20 is available. What is the maximum possible system reliability? How many additional components of each type should be purchased? component: 1 , 2, 3 Reliability: 0.9, 0.8, 0.7 Unit cost: 9, 4, 3arrow_forward
- What is the reliability of the system shown?arrow_forwardDiscuss the concept of Mean Time Between Failures (MTBF) and how it is calculated. Explain its limitations and alternatives for measuring system reliability.arrow_forwardHow can human error affect system reliability, and what measures can mitigate it?arrow_forward
- 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?arrow_forward1. Using examples, differentiate between series and parallel Reliability Block Diagrams (RBD) and show how to calculate system reliability in each case. 2.arrow_forwardIn the context of system reliability, explain the difference between Mean Time Between Failures (MTBF) and Mean Time To Recovery (MTTR). How do these metrics impact system design?arrow_forward
