These tests can sometimes signal an impending failure (for example, iron particles in the oil), and preventive maintenance is then performed (at a relatively low cost), eliminating the risk of failure (failure would result in a relatively high cost). However, oil analysis costs money and it is not perfect- it can indicate that a unit is defective when in fact it is not, and it can indicate that a unit is non-defective when in fact it is. As a possible substitute for oil analysis, the company could simply change the oil periodically, thereby reducing the probability of failure. The fleet manager for the Southern Company, an electrical utility based in Atlanta (parent of Georgia Power), has four alternatives: (1) do nothing, (2) use oil analysis only, (3) replace oil only, or (4) replace oil and do oil analysis. For option (1) the probability of failure is 0.1, and the cost of failure is $1,200. For option (2), the probability of failure remains at 0.1. If the unit is about to fail, the oil analysis will indicate this with probability 0.7; if the unit is not about to fail, the oil analysis will indicate this with probability 0.8. The oil analysis itself costs $20, and if it indicates that failure is about to occur, the oil will be changed at the cost of $14.80 and nravantiva mointanonna will ha narformad The cost of nravantive main anonna to ractora n unit that is about to fail in $500 wherenc Type here to search 51 100% 0 ENG US Virtual Classroom X CO Apps Bookmarks 49 WhatsApp X + G 0 X Other bookmarks Aa 12:23 AM 5/27/2022
