Nettet1. mar. 1993 · First, Johnson's rule, which solves optimally the classical two-machine flow-shop case without setup times and second, an algorithm proposed in [5] for the case where all jobs of a group have to be processed consecutively. This algorithm optimally solves problems with setup times which are very large compared to the processing times. NettetJohnson's algorithm (JA) is perhaps the most classical algorithm in the scheduling area. JA gives the optimal solution to the two machine flow shop to minimize the makespan in polynomial time.
