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?

A) 1 hour
B) 2 hours
C) 4 hours
D) 7 hours
E) 10 hours

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

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

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: Where in the optimum sequence should car A be scheduled?

_____ 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.

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

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

In an assignment model where there are fewer jobs than resources

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

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

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

The following table contains information about five jobs waiting to be processed at work center number three. The sequence that would result using the SPT rule is

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

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.

Which of the following is the last step in the capacity/scheduling chain?

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