Question

Your Company plans to transport 20 horses to a racetrack in Denver. You know that it takes 12 hours to drive directly from Phoenix to Denver. You also know that you have to stop and feed the horses every 2 hours. You also need a six-hour sleep every 10-hour drive. If you were the logistics operations manager responsible for this move, what would be your critical ratio if you had only 2 days left to meet your deadline and you only have to consider feeding the horses and taking your required amount of nap?

Explanation / Answer

Job

A (Travel time)

12 hours

B (Feeding time)

24 intervals in two days

C (Sleeping time)

6 hours for every 10 hours derive

Critical ratio for Job A = Time to due date/Elapsed time to finish the job [2 days = 48 hours]

= 48/12

= 4

Critical ratio for Job B = 48/24 = 2

Critical ratio for Job C = 48/6 = 8

Job B is very important since it has the small ratio.

A value of 1.0 is "on schedule." A value less than 1.0 is behind, and larger than 1.0 is ahead of schedule.

Here all the ratios are greater than 1, so you can reach in ahead of schedule.
