Answer to Question #279424 in Mechanical Engineering for aaron

Question

Find out the reliability using markov analysis for load sharing units?

(b) A manufacturing company operates two production lines when both lines are operating, the production rate on each line is 500 units per hour. At this production rate the failure rate of line 1 is 3 failures per 8-hr day (CFR) and the failure rate of line 2 is 2 failures per 8-hr day. When one line fails, the production rate of the second line must be increased in order to make production quotas. At the increased rate of 800 units per hour, the failure rate of line 1 is 6 per 8 hr day and the failure rate of line is 3 per 8-hr day. Find the reliability and the MTTF and the reliability of the production system over a 1 hr and over an 8 hr production run.

Answer 1

• The first cost of the asset:

Here the formula derived for the book value of an asset will be:

Book Value = Initial cost − Accumulated depreciation 

 

Thus, the first cost will be:

Book Value = Initial cost − Accumulated depreciation

$62,000 = Initial cost − 3 × depreciation/year

$62,000 = Initial cost − $78,000

Initial Cost = $62,000 + $78,000

Initial Cost = $140,000

Part-B)

• The assumed salvage value:

Salvage Value:

Salvage Value = Initial Cost − Total asset life × Depreciation/year

Salvage Value = $140,000 − (5 × $26,000)

Salvage Value = $140,000 − $130,000

Salvage Value = $10,000
