OPS 571T Wk 3 – Apply: Week 3 Assignment

According to the theory of constraints, which of the following is an operational measurement that can be used to measure the firm’s ability to make money?

Multiple Choice

Inventory

Sales

Operating revenue

Unit cost

Overhead per unit

 

 

Which of the following is a “focusing step” of Dr. Eli Goldratt’s theory of constraints?

Multiple Choice

Reduce system constraints.

Reinforce system constraints.

Support system constraints.

If you have no system constraints, make some.

Identify system constraints.

 

 

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.

True or False

True

 

 

Company unions in Japan exist to foster a cooperative relationship with management.

True or False

 

 

Smaller transfer batches give lower work-in-process inventory and faster product flow.

True or False

 

 

Uniform plant loading is where you schedule production with different amounts of the same product each day of the week to permit variation to meet changing demand requirements.

True or False

 

 

In implementing a lean production system, you should work with suppliers to do which of the following?

Multiple Choice

Open facilities near your factory.

Focus workstation capacities.

Backflush.

Provide quality at the source.

Reduce lead times.

 

 

According to the theory of constraints, the term “productivity” is defined as all those actions that bring a company closer to its goals.

True or False

 

 

You have been called in as a consultant to set up a Kanban control system. The first thing to do is to determine the number of Kanban card sets needed. Your research shows that the expected demand during lead time for a particular component is 150 per hour. You estimate the safety stock should be set at 25 percent of the demand during lead time. The tote trays used as containers can hold 8 units of stock, and the lead time it takes to replenish an order is 2 hours. Which of the following is the number of Kanban card sets necessary to support this situation?

Multiple Choice

Uniform plant loading is a process of smoothing the production activity flow to dampen the reaction waves that normally occur in response to schedule variations.

True or False

 

 

Mr. Goldratt’s “theory of constraints” is useful only in manufacturing settings.

True or False

 

 

Quality at the source” requires factory workers to become their own inspectors.

True or False

 

 

On an assembly line, a process batch can be infinite.

True or False

 

 

Which of the following is an approach to dealing with a bottleneck?

Multiple Choice

Keep a buffer inventory in front of it to ensure that it always has something to work on.

Use Johnson’s sequencing rules on bottleneck operations.

Don’t worry about the bottleneck; it will take care of itself.

Move things to a faster bottleneck.

Pay an incentive bonus to workers on the bottleneck operation.

 

 

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.

True or False

 

 

To implement a flow process in developing a lean system a firm might do which of the following?

Multiple Choice

Improve capacity utilization.

Build product in anticipation of demand.

Reduce setup/changeover time.

Eliminate some fixed costs.

Implement groupware.

 

 

One way to find a bottleneck is to run a capacity resource profile.

True or False

 

 

Value stream mapping is used to visualize product flows through various processing steps.

True or False

 

 

The “dollar days” inventory measurement can be used in purchasing to discourage large work-in-process and producing earlier than is needed.

True or False

 

 

According to the theory of constraints, a bottleneck is any resource whose capacity is greater than the demand placed on it.

True or False

 

 

In setting up a kanban control system you need to determine the number of kanban card sets needed. If the expected demand during lead time is 25 per hour, the safety stock is 20 percent of the demand during lead time, the container size is 5, and the lead time to replenish an order is 5 hours, what the number of kanban card sets is needed?

Multiple Choice

An MRP system can allow for product rejects by building a larger batch than is demanded, but a JIT system cannot tolerate poor quality.

True or False

 

 

In a lean production system, we expect to see which of the following?

Multiple Choice

No extra inventory

Extra inventory of critical parts held “just-in-case”

More parts and fewer standardized product configurations

Managers being held responsible for quality of the work turned out

Closer management-labor relationships

 

 

A kanban control system uses a signaling device to regulate JIT flows.

True or False

 

 

In implementing a lean production system you should work with suppliers to do which of the following?

Multiple Choice

Calculate lead times.

Use quality circles.

Freeze windows.

Make frequent deliveries.

Achieve bottom-round management.
