Web1. mar 2005 · An important subclass of flow shop scheduling, permutation schedules, has been studied in the literature. In this subclass, the order in which each machine processes … Flow-shop scheduling may apply as well to production facilities as to computing designs. A 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. Zobraziť viac 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 … Zobraziť viac The sequencing problem can be stated as determining a sequence S such that one or several sequencing objectives are optimized. 1. (Average) Flow time, $${\displaystyle \sum (w_{i})F_{i}}$$ 2. Makespan, Cmax Zobraziť viac 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 Zobraziť viac 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 of each job, execution time is specified. Zobraziť viac 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, F2 prmu Cmax can be solved optimally by using Johnson's Rule.
