If an operation has a design capacity of 168 hours, a planned downtime of 42 hours and an unplanned downtime of 6 hours, what is its efficiency?
A) 71.4%
B) 95.2%
C) 85.1%
D) 75.3%

Question

Quizplus · Accepted Answer

Efficiency is calculated as (Actual Operating Time / Effective Capacity) * 100. Effective Capacity is Design Capacity minus Planned Downtime. Here, Effective Capacity = 168 - 42 = 126 hours. Actual Operating Time = Effective Capacity - Unplanned Downtime = 126 - 6 = 120 hours. Efficiency = (120 / 126) * 100 = 95.2%.
