Question

Indicate the following statements are true or false, and explain why each is true or false: Indicate the following statements are true or false, and explain why each is true or false

E. Similar production lines producing the same products can have the same throughput with different levels of WIP

F. The bottleneck station always has the longest processing time

G. The amount of variability in processing times cause the cycle time to increase and the throughput to decrease

H. The practical worst case performance level is the optimum level of performance that is used to evaluate the actual performance of the line and it is fixed when the amount of work in process is changed

I. The push production system promotes larger work in process levels

J. Non-preemptive stops of the machines are not random occurrences?

K. Steady state concept is important in the queueing analysis ?

Explanation / Answer

E) FALSE

SIMILAR PRODUCTION LINES that produce on ear more similar products, when using separate WIP levels, the total throughput is not guaranteed to be the same

F) False

A bottleneck is the process step with the lowest capacity. It is often the process step with the longest processing time but we generally look at capacities to make a judgment

G) TRUE

Variability is present in all production systems and it causes decrease in throughput and increase in cycle time

H) FALSE

IT DEPICTS A SCENARIO WHEN THE SYSTEM IS WORSE or better THAN practical worst case performance and there is a significant room for improvement

I) TRUE

PUSH SYSTEM promotes larger work in process levels while pull set controls work in process explosions

J) True

K) TRUE

Steady sate assures that the system is in balance where assumptions are made on what is happening and predictions are based on these assumptions
