Concept explainers
a)
To determine: Sequence of jobs based on decision rule Earliest Due Date (EDD).
Introduction: Earliest Due Date is the
b)
To determine: The average job tardiness for the sequence determined using EDD
Introduction: Earliest Due Date is the scheduling rule, which helps to arrange the sequence in the order. Here, job with the earliest due date would be served first. Then, the process would be going on from earliest due date to latest due date.
c)
To determine: The average number of jobs for the sequence determined using EDD
Introduction: Earliest Due Date is the scheduling rule, which helps to arrange the sequence in the order. Here, job with the earliest due date would be served first. Then, the process would be going on from earliest due date to latest due date.
d)
To determine: Whether the SPT would have better result in terms of job tardiness than EDD.
Introduction: Shortest Processing Tine is the scheduling rule, which helps to arrange the sequence in the order. Here, job with the shortest duration would be served first. Then, the process would be going on from shortest to largest duration.

- What information can you get from an average number of jobs (ANJ) in sequencing? a.Higher ANJ means higher work in process. b.Higher ANJ means lower tardiness. c.Higher ANJ means a higher make-span. d.Higher ANJ means longer actual processing time. Higher ANJ means lower flow time.arrow_forwardA work system has five stages with processing times of 58, 247, 91, 262, and 175 mins/unit. A product must go through these stages in a sequential order. What is the bottleneck processing time in mins/unit? (Only enter a number, do not enter any unitsarrow_forwardFind a sequence to minimize the number of tardy jobs (jobs with tardiness > 0). note : please give me excel formulas provide the equations using excelarrow_forward
- Suppose there is a set of jobs to be processed at a resource. Shortest processing timealways sequences the jobs in a different order than first-come-first-served. True or false?a. Trueb. Falsearrow_forwardSharpening your pencil is an operation that may be divided into eight small elemental motions. In MTM terms, each element may be assigned a certain number of TMUs: What is the tota l normal time for sharpening one pencil? Convert your answer into minutes and seconds.arrow_forwardThe earliest-due-date rule always minimizes the maximum tardiness across jobs. True orfalse?a. Trueb. Falsearrow_forward
- What are the tarde offs in Deciding how often update standard times due to minor changes in the work methods.arrow_forwardYou observe a bank and notice that a customer leaves the bank about every five minutes.These five minutes between customers are:a. the capacity of the process.b. the processing time of the last resource.c. the cycle time.d. the lead timearrow_forwardThe unit of measure that is chosen for tracking schedule progress can affect the quality of the work. Question 16 options: True Falsearrow_forward
- So how to calculate the following below: Avg. lateness = ? days Avg. completion time = ?? days Avg. number of jobs in the system = ? jobsarrow_forward492. All system resources are made exclusively available for job till its completion in process of a. Uniprogramming b. Multiprogramming with variable jobs c. Multiprogramming d. Multiprogramming with fixed jobsarrow_forwardWhy does the theory of constraints advocate that a manager’s attention be directed tothe bottleneck of a process?a. It is useful to lower the utilization of the bottleneck.b. The bottleneck has considerable influence on the average flow rate of a process.c. It is important to minimize the buffer inventory in front of the bottleneck.d. First-come-first-served scheduling of jobs at the bottleneck ensures that all jobs havethe same expected waiting time before they are processed at the bottleneck.arrow_forward
