WebMean flow time minimized by SPT • For single-machine scheduling, minimizing the following is equivalent: • Mean flow time • Mean waiting time • Mean lateness • Minimize … Flow-shop scheduling is a special case of job-shop scheduling where there is strict order of all operations to be performed on all jobs. Flow-shop scheduling may apply as well to production facilities as to computing designs. See more 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 … 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 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 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. … See more The sequencing problem can be stated as determining a sequence S such that one or several sequencing objectives are optimized. 1.
