Exam 26: Operations Scheduling

Table J.5 The following three jobs just arrived (end of hour 0)at Workstation A.They are the only ones waiting to be processed. -Use the information in Table J.5.The average past due using the slack per remaining operations (S/RO)rule is:

Utilization is the degree to which equipment,space,or the workforce is currently being used,measured as the ratio of average output rate to the maximum capacity.

Table J.6 All of the following three jobs just arrived (end of hour 0)at Workstation A.They are the only ones waiting to be processed. -Use the information in Table J.6.What is the job sequence at Workstation A,using the critical ratio rule?

The shortest processing time rule tends to produce a large variance in ________.

Table J.5 The following three jobs just arrived (end of hour 0)at Workstation A.They are the only ones waiting to be processed. -Use the information in Table J.5.The average past due using the ratio (CR)rule,is:

Table J.18 -Use the information in Table J.18 and sequence the jobs using the EDD rule.What is the average flow time?

When using the critical ratio (CR)priority sequencing rule:

________ is the amount of time by which a job missed its due date.

A job shop is accompanied by divergent flows and low-to-medium volume output rates.

A(n)________ specializes in medium- to high-volume production and uses line or continuous flow processes.

Table J.18 -Use the information in Table J.18 and sequence the jobs using the SPT rule.What is the average flow time?

Table J.18 -Use the information Table J.18 and sequence the jobs using the SPT rule.What is the average past due?

The percent of work time productively spent by an employee or a machine is called:

Table J.1 The framing department has six jobs waiting to be processed.It is now time zero.Times are expressed in terms of days. -Using the information in Table J.1 and the EDD rule,what is the average early time?

Table J.17 A company must take on seven new projects.Each project has a planning stage and a design stage,and the planning stage must be completed before the design stage can begin.Also,two project teams are available to work on these projects: Team 1 works only on planning stages of projects,and Team 2 works only on design stages of projects.The times to complete the project stage,in days,are shown in the following table. -Using the information in Table J.17 and Johnson's rule,on which day will project F be completed?

Table J.8 Auto Data produces custom engineering testing equipment.The following six jobs are currently in the design department.The time since each one arrived,the processing time,and the due date are shown below.All times are expressed in terms of days.Let now be the beginning of Day 1. -Using the information in Table J.8 and the SPT rule,what is the average days past due?

________ are a set of priority rules that apply to more than one aspect of a job.

Total inventory is equal to:

When choosing a priority sequencing rule:

Table J.9 There are three jobs available for processing at Workstation 1.They just arrived at Workstation 1,at the end of Day 0. -Using the information in Table J.9 and the critical ratio rule,what should be the sequence of jobs processed at Workstation 1?
