Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

Table A.4.6-5 Summarized Life Cycle Costs (LCC) . _ MTBF tHr) Failures/ Availability Downtime Procurement Ten~year Total year Hourslyear cost ($) Operating CosVyear Cost Linear 806.8 10.9 99.5°/O 43.7$3.7M $4.5M $445,673 Ring 1 ,335,942 10.9 99.9°/O .04__ $3.9M $4.1 M $413,652 ~ Parallel ~3.3~1C ~21.7 ~99.9°>, ~1.55*10~ $/.1M ~$7.4M ~ $73,,504 The conclusions are: · The fault tolerant ring has the lowest lO-year cost: $200,000 more to procure but $400,000 less including lO-year operating costs. The linear and ring systems suffer about Me same number of failures per year, but the ring is down less than one hour per year due to its redundancy. In reality, the ring and the parapet system operate many years between unavailability failures of more Man a few seconds (resulting from switching to parapet circuits). The parallel system is $2.4M more expensive to operate Man Me linear system. If geography does not permit a cost-effec~ve ring, a parallel system is much more expensive. To justify Me redundancy and lower downtime, operations benefits should be $54,920~our (=$2.4M / 43.7 fur). A.4.7 References and Standards References I.
