Johnson's Rule results in an optimal sequence when
A)there are only two serial processes.
B)all jobs follow the same sequence through the processes.
C)the objective is to minimize makespan.
D)All of the above must be true for an optimal sequence

Quizplus · Accepted Answer

Johnson's Rule is used to find an optimal sequence when there are two serial processes, and the objective is to minimize the makespan. It can be used for different job sequences as well, so option B is not a requirement for the rule to provide an optimal solution. Therefore, all options are true and must hold for an optimal sequence to be obtained.
