Answer to Problem 10PA

After necessary calculations, it can be seen that the average flow time is 25, lateness is 9.5, and tardiness is 11.25.

Explanation of Solution

Under the given order rule:

The average lateness will be;

  =14+3+7+12+6+16+8+388=768=9.50

The average tardiness will be;

  =0+3+7+12+6+16+8+388=908=11.25
