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, … See more There are m machines and n jobs. Each job contains exactly m operations. The i-th operation of the job must be executed on the i-th machine. No machine can perform more than one operation simultaneously. For each operation … See more The proposed methods to solve flow-shop-scheduling problems can be classified as exact algorithm such as branch and bound and heuristic algorithm such as genetic algorithm See more The sequencing problem can be stated as determining a sequence S such that one or several sequencing objectives are optimized. See more As presented by Garey et al. (1976), most of extensions of the flow-shop-scheduling problems are NP-hard and few of them can be solved optimally in O(nlogn); for example, … See more • Open-shop scheduling • Job-shop scheduling See more
Webnon-preemptive flow-shop problem is also shown to be NP-complete. The best known algorithms for all known NP-complete problems have a worst case computing time larger than any polynomial in the problem size. Fur- thermore, any NP-complete problem has a polynomial time algorithm iff all the others also have polynomial time algorithms [9—11]. hiding my face emojiWebMar 17, 2024 · This paper addresses the hybrid flow shop scheduling problem by considering job rejection to minimize the sum of the total tardiness cost of the scheduled jobs and total cost of the rejected jobs as a single-objective problem.
