The following jobs are waiting to be processed at Rick? Solano's machine center.? Solano's machine center has a relatively long backlog and sets a fresh schedule every 2? weeks, which does not disturb earlier schedules. Below are the jobs to be scheduled? today, which is day 241 ?(day 241 is a work? day). Job names refer to names of clients and contract numbers. Compute all times based on initiating work on day 241.

(Job) (Date Job Received) (Due Date Duration (days))

BR-02 225 270 25

CX-01 230 320 35

DE-06 235 360 40

RG-05 231 310 30

SY-11 228 300 15

Using the FCFS? (first come, first? served) decision rule for sequencing the jobs, the order is:

The average tardiness (job lateness) for the sequence developed using the FCFS rule? =

The percentage utilization for the sequence developed using the FCFS rule?

The average completion time for the sequence developed using the FCFS rule?

The average number of jobs in the system for the sequence developed using the FCFS rule? =

Expert Solution

Using the FCFS (first come, first served) decision rule for sequencing the jobs, the order is:

BR-02, SY-11, CX-01, RG-05, DE-06

The average tardiness (job lateness) for the sequence developed using the FCFS rule = 12

The percentage utilization for the sequence developed using the FCFS rule = 32.88 %

The average completion time for the sequence developed using the FCFS rule = 78

The average number of jobs in the system for the sequence developed using the FCFS rule = 2.69

Problem 3: Rick goes to career fair booths in the technology sector for data science jobs (e.g., Facebook, Amazon, IBM, etc.). His likelihood of receiving an off-campus interview invitation after a career fair booth visit depends on how well he did in MIE 263. Especially, an A in MIE 263 results in a probability p=0.95 of obtaining an invitation, whereas a C in MIE 263 results in a probability of p=0.15 of an invitation. (Whether a student will get an...

The amount of time that a truck spends in waiting at the distribution center for unloading is a random variable with a mean of 30 minutes and a standard deviation of 20 minutes. Suppose that a random sample of 9 trucks is observed. Find the probability that the average waiting time of trucks is: (1) Less than 20 minutes (2) Between 20 and 40 minutes
