Question

The priority rule where jobs are processed according to the smallest ratio of time until due date to processing time is:

a) critical ratio (cr).
b) earliest due date (edd).
c) first come, first serve (fcfs).
d) minimum slack time (mst).
e) shortest processing time (spt).

Answer 1

The priority rule where jobs are processed according to the smallest ratio of time until due date to processing time is called critical ratio (CR).

This rule is used in production planning and scheduling to prioritize jobs based on their due dates and processing times.

Step-by-step explanation:

The priority rule where jobs are processed according to the smallest ratio of time until due date to processing time is called critical ratio (CR).

This rule is used in production planning and scheduling to prioritize jobs based on their due dates and processing times.

For example, let's say we have two jobs: Job A has a due date of 10 days from now and a processing time of 5 days, while Job B has a due date of 7 days from now and a processing time of 3 days.

We can calculate the critical ratio for each job by dividing the time until due date by the processing time. In this case, the critical ratio for Job A is 2 (10/5) and for Job B is 2.33 (7/3).

Based on the critical ratios, Job A would be given a higher priority because its critical ratio is smaller, indicating a tighter deadline in relation to its processing time.
