CMS Process Engineering & Optimization 4

Question 1

Takt time in a manufacturing process is calculated as:

Accepted Answer

Available production time divided by customer demand rate

Answer

Takt time sets the pace of production by dividing available production time by the rate of customer demand.

Question 2

Which statistical tool is used to quantify the relationship and strength of correlation between two process variables?

Accepted Answer

Scatter diagram

Answer

A scatter diagram plots pairs of data points to visually assess and quantify the correlation between two variables.

Question 3

In FMEA, Risk Priority Number (RPN) is calculated by multiplying:

Accepted Answer

Severity × Occurrence × Detection

Answer

RPN = Severity × Occurrence × Detection, and higher RPN values indicate failure modes requiring immediate corrective action.

Question 4

A manufacturing engineer implements continuous flow to replace batch processing. The primary benefit is:

Accepted Answer

Reduced work-in-process inventory and shorter lead times

Answer

Continuous flow reduces WIP buildup and waiting time between operations, dramatically cutting total lead time.

Question 5

Which type of maintenance strategy schedules equipment service based on calendar intervals regardless of actual condition?

Accepted Answer

Preventive (time-based) maintenance

Answer

Preventive maintenance uses fixed time intervals (e.g., monthly or annually) to service equipment before failures occur.
