Webmachines and a machine is not kept idle if a job for the machine is ready for processing. Noting that minimizing the makespan is equivalent to minimizing idle time on the last machine, Johnson proposed an algorithm to solve the n/2/F/Cmax problem in O(n log n) time. Johnson further presented an algorithm to solve the Webaco-flowshop. A Java Program to solve the Flow-Shop Scheduling Problem using Ant Colony Algorithms. The implemented method is based on the paper "An ant approach to …

WebAbstract. This paper is an attempt to study general flow shop scheduling problem in which processing time of jobs is associated with probabilities under no-idle constraint. The objective of this paper is to develop a heuristic algorithm to flowshop scheduling so that no machine remains idle during working for any given sequence of jobs. The proposed … Webof idle time in the schedule can be advantageous. See [6] for a literature review about scheduling with inserted idle time. The problem parameters for all the formulations studied in the rest of this work are (a) n: the number of jobs, (b) m: the number of machines, (c) p ik: the processing time of job i on machine k, and (d) d i: the due date ... optiongeek.com
