Question

Take Test: Unit VIII Assessment

Your response should be at least 200 words in length. You are required to use at least your textbook as source material for your response. All sources used, including the textbook, must be referenced; paraphrased and quoted material must have accompanying citations.

What are the objectives of Johnson’s Rule? Define the steps involved in applying Johnson’s Rule.

Describe how cost accounting is sometimes antithetical to the Theory of Constraints (TOC).

Discuss the most common approach to determining the appropriate run length of a simulation.

You have run a capacity resource profile on your shop. Products have been routed sequentially through resources A, B, C, and D. The capacity resource profile tells you that resource A is scheduled at 95% of capacity, resource B at 80% of capacity, resource C at 130% of capacity, and resource D at 100% of capacity. Assuming that the data we used to calculate the capacity resource profile was accurate, how would you employ the “drum, buffer, rope” thinking?

What is the role of judgment and evaluation in simulation?

Where in a dependent events sequence should an in-process quality inspection be placed? Why there?

In discussing batch size on an assembly line, the textbook makes the point that “one” and “infinity” are equally correct answers. How can this be?

What is sub-optimization in scheduling?

Johnson Rule

Johnson rule was to be the technique which could be used for the minimization of completion time for a job’s group which was process on two machines and at successive work centers and his rule reduced the number of idle duration between two work centers. His method could find the shortest makespan in three work centers if the additional constraints were met. The objectives of Johnson’s rule included the minimization of processing time for sequencing a group of jobs through two work centers, minimization of total idle times on the machines, and the minimization of flow time from the first jobs’ beginning until the finishing of last job.

There were several kinds of steps involved in Johnson’s rule in minimizing the processing duration of groups. In this, Johnson’s rules included the four kinds of steps that all group of jobs were to be listed and the processing time of each machine was also to be listed, selection of job with the shorted processing time was to be the step which referred that if the shortest duration lies on the first machine, the job was to be…
