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.

- Describe the concept of Mean Time Between Failures (MTBF) and its significance in system reliability assessment.arrow_forwardThe 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_forwardi need the answer asaparrow_forward
- Explain 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_forwardDiscuss the concept of Mean Time Between Failures (MTBF) and how it is calculated. Explain its limitations and alternatives for measuring system reliability.arrow_forward
- How can human error affect system reliability, and what measures can mitigate it?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_forward1. Using examples, differentiate between series and parallel Reliability Block Diagrams (RBD) and show how to calculate system reliability in each case. 2.arrow_forward
- What is the reliability of the following parallelproduction process? R1 5 0.95, R2 5 0.90, R3 5 0.98.arrow_forwardA student preparing for finals has had a reoccurring dream about oversleeping for a final. On the night before the final, he creates the following wake-up system. Calculate the overall system reliability. The power from the power company is 0.98 reliable. The battery-operated clock is 0.95 reliable and has a back-up alarm clock with reliability of 0.85. Two friends, working in parallel are 0.70 and 0.60 reliable respectively. Will the student get up on time?arrow_forward*THE TABLE RELATED TO THIS QUESTION IS ATTACHED* Thank you! The Mid-West Enterprises currently sells a product consisting of three components arranged in series (i. e., all three components needs to be working in good condition) with the reliability of each component as shown in Figure 1 below. However, they want to improve the reliability of their product and are considering two alternate designs that mix the series-parallel configurations with the reliability of each component shown in Figures 2 and 3 below. Ignoring the cost and all other aspects, the management of Mid-West Enterprises has asked you to analyze each design option. Therefore, please answer the following questions clearly stating the logic and calculations needed. What is the reliability of each design in Figures 1 through 3 above?arrow_forward
