The following jobs are waiting to be processed at the same machine center. Jobs are logged as they arrive:

Job Due Date Duration (days)
A 314 5
B 315 3
C 313 8
D 312 16
E 325 40

All dates are specified as manufacturing planning calendar days. Assume that all jobs arrive on day 275. Assume each job starts at the beginning of the day and finishes at the end of the day (a job that begins on day 275 and takes 8 days will finish on day 282, and the next job begins in the morning of day 283). Compute all times based on initiating work on day 275.

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

Respuesta :

Answer:

The average job lateness for the sequence developed is 328 days

Explanation:

Given that the initial work day is base on day 275, the following is going to be the new sequence of the given jobs:

Job Due Date

A 318 5

B 317 3

C 320 8

D 327 16

E 364 40

Therefore, the average job lateness is calculated as follows:

(318+317+320+327+364)/5=328 Days
