نویسندگان

چکیده

A discrete whale optimization algorithm (DWOA) is presented to solve the no-wait flow shop scheduling problem (NWFSSP) with objective makespan. An effective combination of nearest neighbor (NN) and standard deviation heuristics (SDH) used acquire initial solutions population. After that, three crossover operators, two-point (TPX), multiple-point (MPX) job-based (JBX) are designed mimics humpback whales hunting process. Moreover, dynamic transform mechanism search process better balance exploration exploitation ability DWOA. In order further improve effect DWOA, parallel neighborhood (PNS) serial (SNS) selected execute local promoting global scheme, respectively. Finally, test performance extensive experiments conducted on benchmarks by Reeves Taillard, which contain parameters tuning, effectiveness improvement strategies in DWOA comparison several existing algorithms. From experimental results, it validated that improved mechanisms can find makespan values compared other algorithms for solving NWFSSP.

Solving Re-entrant No-wait Flow Shop Scheduling Problem

In this study, we consider the production environment of no-wait reentrant flow shop with the objective of minimizing makespan of the jobs. In a reentrant flow shop, at least one job should visit at least one of the machines more than once. In a no-wait flowshop scheduling problem, when the process of a specific job begins on the first machine, it should constantly be processed without waiting ...

Evolutionary Hybrid Particle Swarm Optimization Algorithm for Solving NP-Hard No-Wait Flow Shop Scheduling Problems

The no-wait flow shop is a flowshop in which the scheduling of jobs is continuous and simultaneous through all machines without waiting for any consecutive machines. The scheduling of a no-wait flow shop requires finding an appropriate sequence of jobs for scheduling, which in turn reduces total processing time. The classical brute force method for finding the probabilities of scheduling for im...

A heuristic for no-wait flow shop scheduling

This paper presents an efficient heuristic method to minimize total flow time in no-wait flow shop scheduling. It is based on the assumption that the priority of a job in the initial sequence is given by the sum of its processing times on the bottleneck machines. Empirical results demonstrate the superiority of the proposed method over the best-known heuristics in the literature, while remainin...
