Journal ArticleDOI
Multi-objective adaptive large neighborhood search for distributed reentrant permutation flow shop scheduling
TL;DR: The aim of the study is to determine the number of factory needs to be used, jobs assignment to certain factory and sequence of job assigned to the factory in order to simultaneously satisfy three objectives of minimizing makespan, total cost and average tardiness.
Journal ArticleDOI
Evaluation of turned and milled surfaces roughness using convolutional neural network

TL;DR: This study proposes the use of convolutional neural network to evaluate the surface roughness directly from the digital image of surface textures, which avoids feature extraction since this step is integrated inside the network during the convolution process.
Journal ArticleDOI
An Integrated MCDM Model for Conveyor Equipment Evaluation and Selection in an FMC Based on a Fuzzy AHP and Fuzzy ARAS in the Presence of Vagueness
TL;DR: An integrated multi-criteria decision making (MCDM) model of a fuzzy AHP and fuzzy ARAS for conveyor evaluation and selection and results obtained demonstrate practical potential for the implementation of FMCs are presented.
Journal ArticleDOI
Multi-objective distributed reentrant permutation flow shop scheduling with sequence-dependent setup time
TL;DR: In this article, an improved version of the multiobjective adaptive large neighborhood search (MOALNS) is proposed as a solution method for the sequence-dependent DRPFS with the aim to minimize the makespan, production cost, and tardiness.
Journal ArticleDOI
Non-dominated sorting biogeography-based optimization for bi-objective reentrant flexible manufacturing system scheduling
TL;DR: It is concluded that the developed NSBBO and its variants are suitable alternative methods to achieve the bi-objective satisfaction of reentrant FMS scheduling problem.
