- What happens to availability when the mean time between failures (MTTR) gets close to zero? Is it possible to adequately convey the current situation?arrow_forwardAs the engineering manager of air conditioning units for Acme Bus Company, you receive a notice that there might be some flaw in the units because a virus-like upper respiratory infection has spread through the school children who were bussed a long way for a special summer session. The suspicion is reinforced early in the fall school year when only a few of the 80 students showed up at the pick-up points two weeks after the bus runs started. These are new buses put into service at the beginning of the summer, thus there is no previous experience with them. You go to your boss to advise an immediate withdrawal of the buses but he refuses on the grounds that there is no evidence. How should you proceed? What steps should you take to resolve the issues? Write briefly analyzing this case and explaining your answer.arrow_forwardWhat is the role of configuration management in ensuring system reliability and consistency?arrow_forward
- Maintenance may be classified into FOUR (4) categories. Describe it in detail and explain the type of maintenance.arrow_forwardOakwood Hospital is considering using ABC analysis to classify laboratory SKUs into three categories: those that will be delivered daily from their supplier (Class A items), those that will be controlled using a continuous review system (B items), and those that will be held in a two-bin system (C items). The following table shows the annual dollar usage for a sample of eight SKUs. Rank the SKUs, and assign them to their appropriate category. SKU Code Dollar Value Annual Usage 1 2 3 4 5 6 7 8 $0.01 $0.03 $0.45 $1.00 $4.50 $0.90 $0.30 $1.50 1,200 120,000 100 44,000 900 350 70,000 200arrow_forwardWhat is the impact on availability as the mean time between failures (MTTR) approaches zero?
