CPS Analysis & Optimization 3

Question 1

Which simulation method is best suited for analyzing the effect of random variation in a complex process with multiple interdependent steps?

Accepted Answer

Monte Carlo simulation

Answer

Monte Carlo simulation runs thousands of iterations with randomly sampled input values to model the probabilistic behavior of complex systems.

Question 2

A process produces 500 units; 30 have at least one defect and 12 units are scrapped. What is the first pass yield?

Accepted Answer

94.0%

Answer

First pass yield equals units passing without any defect divided by total units: (500−30)/500 = 470/500 = 94.0%.

Question 3

In the Theory of Constraints, which step follows identifying the system constraint?

Accepted Answer

Exploit the constraint

Answer

After identifying the constraint, the next step is to exploit it — maximize its output before investing in additional resources.

Question 4

A control chart shows eight consecutive points above the centerline but within control limits. This pattern indicates:

Accepted Answer

A special cause is likely present

Answer

Eight or more consecutive points on one side of the centerline is a Western Electric run rule violation indicating a non-random special cause.

Question 5

Which analysis technique maps how information and materials flow from supplier to customer to identify bottlenecks and waste?

Accepted Answer

Value stream mapping

Answer

Value stream mapping documents every step, delay, and information flow across the entire process from supplier input to customer delivery.
