Moore's rule is a technique to minimize the number of late jobs for a group of jobs to be processed on one work centre/machine.

The elimination of idle time on both bottleneck and non-bottleneck operations is equally important.

The operations manager of a body and paint shop has five cars to schedule for repair.He would like to minimize the make-span to complete all work on these cars.Each car requires body work prior to painting.The estimates of the times required to do the work at each of the two stations are as follows: Using Johnson's rule where in the optimum sequence should car E be scheduled?

For the jobs listed below,which processing sequence would result using Johnson's Rule? Processing time (hrs.) 11eab92b_c479_cbf3_99e6_89f1b7be27d5

For the Theory of Constraints,the transfer batch denotes a portion of the production lot that could be moved to the bottleneck operation.

Forward scheduling is based on completing jobs exactly on their due date.

Monitoring and managing the work flow at each work centre on the shop-floor of a production facility is called:

A major reason for scheduling difficulty is variability in setup times,processing times,interruptions,and changes in the set of jobs.

In the drum-buffer-rope conceptualization used in the theory of constraints,the "drum" that sets the pace for production refers to:

In scheduling staff for services,flexible capacity is achieved by:

When sequencing jobs with sequence-dependent setup times the goal is to:

Given the following data for jobs awaiting processing at a manufacturing cell in which jobs are first processed by machine A,then by Machine B: In developing the sequence which will minimize make-span,what is the second job to be added to the sequence?

For services,the process of assigning work shifts to staff begins with forecasting the amount of work to be done during each hour (or shift)during the time period the schedule is being planned.

The total time needed to complete a group of jobs from the beginning of the first job to the completion of the last job is called the:

A schedule/control Gantt chart is a visual representation of progress on the shop-floor which shows _______ on a vertical axis,and _______ on the horizontal axis.

Scheduling that starts with the present time and continues into the future is called:

Two different approaches to load work centres in job scheduling are:

The purpose of a Gantt chart is to:
