All are techniques for dealing with bottlenecks.

Which of the following is one of the four principles of bottleneck​ management? A. Increasing capacity at bottleneck stations is a mirage. B. Release work orders to the system at the​ bottleneck's capacity pace. C. Lost time at a​ non-bottleneck is lost system capacity. D. Increased​ non-bottleneck capacity is increased system capacity. E. Bottlenecks should be moved to the end of the system process.

B. Release work orders to the system at the​ bottleneck's capacity pace.

The third step in Theory of Constraints​ application, "subordinate all other decisions to Step​ 2," means​ that: A. the analyst should seek to increase capacity of both the bottleneck and non-bottleneck resources. B. the analyst should schedule non-bottleneck processes to support the bottleneck schedule. C. the analyst should wait for authorization before proceeding with any system-wide changes. D. the analyst should seek to increase capacity of only the bottleneck resources.

B. the analyst should schedule non-bottleneck processes to support the bottleneck schedule.

Consider consecutive processes A-B-​C, where process A has a capacity of 20 units per​ hour, process B has a capacity of 25 units per​ hour, and process C has a capacity of 30 units per hour. Where would an operations manager want any​ inventory? A. in front of process C. B. in front of process B. C. in front of process A. D. Inventory should not exist anywhere

C. in front of process

There are three consecutive steps in a customer service process. The first two steps are each capable of serving 25 customers per hour while the third step can process only 20 customers per hour. Which of the following statements regarding this system is​ true? A. The entire system is capable of processing 25 customers per hour. B. The first and second steps are bottlenecks for the system. C. There are floating bottlenecks in the system. D. If the first two steps are run at full​ capacity, then the third step has a waiting line.

D. If the first two steps are run at full​ capacity, then the third step has a waiting line.

The second step in Theory of Constraints​ application, "exploit the​ bottleneck(s)," means that the analyst​ should: A. repeat the analysis process to look for other bottlenecks. B. consider increasing capacity of the bottleneck. C. schedule nonminusbottleneck resources to support the bottleneck. D. create a schedule that maximizes the throughput of the bottlenecks.

D. create a schedule that maximizes the throughput of the bottlenecks.

D. when the bottlenecks need work.
