Flow shop scheduling example
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 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. Taillard provides … See more The sequencing problem can be stated as determining a sequence S such that one or several sequencing objectives are optimized. 1. (Average) … 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 • Open-shop scheduling • Job-shop scheduling See more WebFlow shop scheduling problems widely exist in industrial production and mechanical manufacturing. For example, in a steel-making process, molten steel is casted into …
