B. Do not balance capacity, balance the flow
C. Do not allow bottlenecks to govern the flow of the line
D. An hour saved at a bottleneck operation is a mirage
E. A the amount in a process batch should be fixed when the batch is begun and not changed over time or along its route
Q:
Which of the following is one of Dr. Eli Goldratt's rules of production scheduling for optimized production technology?
A. Utilization and activation of a resource are not the same
B. Do not allow bottlenecks to govern the flow of the line
C. An hour lost at a bottleneck saves an hour for the entire system
D. Balance the capacities, not the flows
E. The Level of utilization of a bottleneck resource is not determined by its own potential but by some other constraint in the system
Q:
Looking at the loads that are placed on each resource by the products that are scheduled through them is called process flow profiling.
Q:
The term Dependent Events refers to a process sequence.
Q:
Departments within a firm often are at odds with each other because reward systems are often not synchronized with the basic goal of the firm: to make money.
Q:
JIT requires a stable production Level. When compared to synchronous manufacturing this is viewed as a negative aspect of JIT.
Q:
JIT requires vendors to be located nearby. When compared to synchronous manufacturing this is viewed as an advantage of JIT.
Q:
JIT requires work-in-process when used with kanban so there is inventory to pull. When compared to synchronous manufacturing this is viewed as a negative aspect of JIT.
Q:
The synchronous manufacturing approach uses backward scheduling.
Q:
The "dollar days" inventory measurement can be used in purchasing to discourage large work-in-process and producing earlier than is needed.
Q:
The "dollar days" inventory measurement results from a complex algorithm used to compute individual units of inventory and their respective ordering and holding costs.
Q:
The "dollar days" inventory measurement is chiefly used to focus management's attention on where inventory is located.
Q:
A process batch can be no larger than the transfer batch.
Q:
Larger transfer batches give shorter lead times and lower inventories and there is more material handling than smaller transfer batches.
Q:
Rather than try to adjust the master production schedule to change resource loads, it is more practical to control the flow at each bottleneck or CCR to bring capacities in line.
Q:
Transfer batch is another term for process batch.
Q:
Smaller transfer batches give lower work-in-process inventory and faster product flow.
Q:
On an assembly line a transfer batch can be one unit.
Q:
On an assembly line a process batch can be infinite.
Q:
A synchronous manufacturing system does not have excess capacity throughout the system, except for a bottleneck.
Q:
An MRP system can allow for product rejects by building a larger batch than is demanded, but a JIT system cannot tolerate poor quality.
Q:
Buffer inventory in front of a bottleneck is called a time buffer.
Q:
A way to find a bottleneck is to use one's knowledge of a particular plant, look at the system in operation and talk with supervisors and workers.
Q:
One way to find a bottleneck is to run a capacity resource profile.
Q:
According to the theory of constraints, Throughput is the rate at which money is generated by the system through sales.
Q:
According to the theory of constraints, throughput is the rate at which product is passed through the manufacturing system.
Q:
According to the theory of constraints, a capacity-constrained resource (CCR) is one whose utilization is close to capacity and could be a bottleneck if it is not scheduled carefully.
Q:
According to the theory of constraints, capacity is the time available for production.
Q:
According to the theory of constraints a non-bottleneck is any resource where capacity is less than the demand placed on it.
Q:
According to the theory of constraints a bottleneck is any resource whose capacity is greater than the demand placed on it.
Q:
According to the theory of constraints it is wrong to for manufacturers to try to match capacity with demand by attempting to balance capacity across a sequence of processes. Unbalanced capacity is better.
Q:
According to the theory of constraints the term productivity is defined as all those actions that bring a company closer to its goals.
Q:
Mr. Goldratt's "Theory of Constraints" is useful only in manufacturing settings.
Q:
From an operations standpoint, one of the goals of the firm under the theory of constraints is to increase throughput while simultaneously reducing inventory and reducing operating expense.
Q:
The operational measure of throughput is "the rate at which money is generated by the system through production of goods and services that might be sold".
Q:
Dr. Eli Goldratt feels that the goal of a firm is to make useful products efficiently.
Q:
Synchronous manufacturing refers to the entire production process working together in harmony to achieve the goals of the firm.
Q:
OPT stands for optimal purchasing technique.
