Ron Satterfield's excavation company uses both Ganit scheduling charts and Gantt load charts. Today, which is the end of day 7, Ron is reviewing the Gantt chart depicting these schedules: Job #151 was scheduled to begin on day 3 and to take 5 days. It got started on time and is 1 day ahead of schedule. Job #177 was scheduled to begin on day 1 and take 4 days. It is currently on time. Job #179 was scheduled to start on day 6 and take 2 days. It actually got started on day 5 and is progressing according to plan. Job #211 was scheduled to begin on day 5, but missing equipment delayed it until day 6. It is progressing as expected and should take 3 days. Job #215 was scheduled to begin on day 5 and take 5 days. It got started on time but has since fallen behind 1 day. This exercise contains only part a a) Add the actual progress to the Gantt schedule shown on the right (on which the planned timings have been already plotted as blue lines).

Given the data below, using the SPT heuristic sequencing rule, determine the completion date and tardiness for each job as well as the average completion time and average tardiness for all four jobs. Which of the following statements is true? Job Processing time (days) Due date (in days) A 10 10 B 5 8 C 15 25 D 8 15 a.Jobs B and D will have no tardiness b.The tardiness for Job A is 12 days c.The average tardiness is 19.75 d.The average completion time is 6.5
state whether or not each situation would be considered “compensable time” (and why or why not). An employee of a fast food chain has to arrive at work 15 minutes early to change into the“mascot” costume and it typically takes another 15 minutes at the end of the shift to change outof the costume and properly store it. Due to the cost of the costume, employees are notallowed to take the costume home. The “mascots” typically work from 10am – 2pm, to coverthe lunch rush periods. How much time would be “compensable” for the mascots, assumingthe conditions/schedule listed above?2) George is a Radiology Technician at a local hospital and when on call, is required to be nofurther than 30 minutes away from the facility. Is the “on call” time, compensable?
So how to calculate the following below: Avg. lateness = ? days Avg. completion time = ?? days Avg. number of jobs in the system = ? jobs
The following jobs are waiting to be processed at the same machine center. Jobs are logged as they arrive: In what sequence would the jobs be ranked according to the following decision rules: (a) FCFS, (b) EDD, (c) SPT, and (d) LPT? Alldates are specified as manufacturing planning ca.lendar days. Assumethat all jobs arrive on day 275. Which decision is best and why?
