Final answer:
Johnson's rule in Operations Management minimizes the makespan or total time taken by two work centers to complete their tasks.
Step-by-step explanation:
Johnson's rule is used in Operations Management to schedule two work centers. The goal of Johnson's rule is to minimize the makespan, which is the time required to complete all the jobs. In other words, it aims to minimize the total time taken by the work centers to complete their tasks.
For example, let's say there are two work centers, A and B, and four jobs. Johnson's rule helps to determine the sequence in which the jobs should be assigned to the work centers to reduce the overall time taken.
By minimizing the makespan, Johnson's rule helps to increase efficiency and productivity in production processes.
