Operating prioritizes the refrigerated trucks found in grading, not all the way to reduce the waiting time down, but there are many possible ways to reduce the waiting time down. Which, in check in order to get the ship on Monday summarized in Figure 5 and 6, respectively, is how the First Come First Served spent waiting to receive the load by an average of 317 hours and 25 minutes. And when grading with Earliest Due Date is found to take the lead rather than ordering the same (First Come First Served) is up to 26%, which other methods can reduce the waiting time was as follows: Critical Ratio. reduce the waiting time was 12% Priority Queuing reduce the waiting time was 22% Shortest Processing Time reduce the waiting time was 24% Longest Processing Time reduce the waiting time was 12% and Weighted Fair Queuing reduce the waiting time to 24% by day. Monday is the ranking of the most powerful ranking Shortest Processing Time, Weighted Fair Queuing and Priority Queuing.
