Permutation flow-shop scheduling problem
WebNP -complete problems form an extensive equivalence class of combinatorial problems for which no nonenumerative algorithms are known. Our first result shows that determining a shortest-length schedule in an m -machine flowshop is NP -complete for m ≥ 3. (For m = 2, there is an efficient algorithm for finding such schedules.)

WebA special type of flow shop scheduling problem is the permutation flow shop scheduling problem in which the processing order of the jobs on the resources is the same for each subsequent step of processing. We used genetic algorithms to optimize permutation flow shop scheduling problems on the basis of their makespan values. Flow-shop scheduling is an optimization problem in computer science and operations research. It is a variant of optimal job scheduling. In a general job-scheduling problem, we are given n jobs J1, J2, ..., Jn of varying processing times, which need to be scheduled on m machines with varying processing power, while trying to minimize the makespan – the total length of the schedule (that is, when all the jobs have finished processing). In the specific variant known as flow-shop schedulin…
