_____ is a technique that managers can utilize in order to minimize the makespan for a group of jobs to be processed on two machines or at two work centers.

Splitting a large lot after one operation beyond a bottleneck operation would reduce the overall waiting time of the bottleneck operation.

The theory of constraints has a goal of maximizing flow through the entire system.

The following table contains information about five jobs waiting to be processed at work center number three. Using the EDD rule, the sequence of jobs would be

The operations manager of a body and paint shop has five cars to schedule for repair. He would like to minimize the makespan to complete all work on these cars. Each car requires body work prior to painting. The estimates of the times required to do the body and paint work on each are as follows: What is the idle time at the paint work center for the optimal schedule?

Line balancing is a major factor in the design and scheduling of low-volume systems because of batch processing.

The quantity sent to a bottleneck operation could be split into two or more process batches to better utilize a bottleneck resource rather than process the entire batch.

A Gantt chart is a basic scheduling tool that works best for high-volume systems.

In theory of constraints scheduling, the __________ refers to the schedule and the __________ refers to inventory used to ensure that the bottleneck is never idle.

Ensuring that the constraining resource is used to its maximum is an example of constraint

Average completion (flow) time for a schedule sequence at a work center is

Which of the following is present in the manufacturing scheduling hierarchy but is absent in the service scheduling hierarchy?

The operations manager of a body and paint shop has five cars to schedule for repair. He would like to minimize the makespan to complete all work on these cars. Each car requires body work prior to painting. The estimates of the times required to do the body and paint work on each are as follows: Where in the optimum sequence should car A be scheduled?

Scheduling in service systems often takes the form of: (I) appointment systems. (II) reservation systems. (III) makespan systems.

In an assignment model where there are fewer jobs than resources

The SPT priority rule always results in the lowest average completion time.

The Hungarian method is limited to a maximum of two jobs per resource.

Makespan is the total time needed to complete a group of jobs.
