The two … In operations research, Johnson's rule is a method of scheduling jobs in two work centers. Its primary objective is to find an optimal sequence of jobs to reduce makespan (the total amount of time it takes to complete all jobs). It also reduces the amount of idle time between the two work centers.

Nettetmaxproblem, Johnson (1954) gave a decision rule, now popularly called Johnson’s rule: For any two jobs J i,J j∈ N, if min{p i,q j} ≤ min{q i,p j}, then schedule job J i earlier than job J j. Based on this rule, a solution algorithm, known as Johnson’s algorithm, can be designed, which has a time complexity of O(nlogn).

NettetJohnson's algorithm is one approach that can often be applied. The algorithm is easily stated and understood, and can be readily implemented in SAS®. In addition to directly helping with scheduling, the programming illustrates some interesting SAS capabilities, and the final code is very simple and straightforward. Background and Introduction NettetJohnson’s Rule is: From the list of unscheduled jobs, select the one with the shortest processing time in either work center. If the shortest time is at the first work center, do the job first in the schedule otherwise do the job last in the schedule. Remove the job assigned in Step 2 from the list of unscheduled jobs.
