Madureira, Ana Maria; Abraham, Ajith; Varela, M.L.R.; Castillo, Oscar; Ludwig, Simone[Excerpt ] Welcome to Porto, Portugal, and to the 18th International Conference on HybridIntelligent Systems (HIS 2018); the 10th International Conference on SoftComputing and Pattern Recognition (SoCPaR 2018); and the 13th InternationalConference on Information Assurance and Security (IAS 2018) held at InstitutoSuperior de Engenharia do Porto (ISEP) during December 13–15, 2018.Hybridization of intelligent syst...
Study on the Impact of the NS in the Performance of Meta-Heuristics in the TSP
Santos, A. S.; Madureira, Ana Maria; Varela, M. L. R.Meta-heuristics have been applied for a long time to the Travelling Salesman Problem (TSP) but information is still lacking in the determination of the parameters with the best performance. This paper examines the impact of the Simulated Annealing (SA) and Discrete Artificial Bee Colony (DABC) parameters in the TSP. One special consideration of this paper is how the Neighborhood Structure (NS) interact with the...
Evaluating the Effectiveness of Bayesian and Neural Networks for Adaptive Sched...
Cunha, Bruno; Madureira, Ana Maria; Pereira, João Paulo; Pereira, IvoThe ability to adjust itself to users’ profile is imperative in modern system, given that many people interact with a lot of information in different ways. The creation of adaptive systems is a complex domain that requires very specific methods and the integration of several intelligent techniques, from an intelligent systems development perspective. Designing an adaptive system requires planning and training o...
Scheduling Single-Machine Problem Oriented by Just-In-Time Principles - A Case ...
Dantas, Joana D.; Varela, Maria Leonilde Rocha; Madureira, Ana MariaDevelopments in advanced autonomous production resources have increased the interest in the Single-Machine Scheduling Problem (SMSP). Until now, researchers used SMSP with little to no practical application in industry, but with the introduction of multi-purpose machines, able of executing an entire task, such as 3D Printers, replacing extensive production chains, single-machine problems are becoming a central ...
An ordered heuristic for the allocation of resources in unrelated parallel-mach...
E Santos, André Serra; Madureira, Ana Maria; Varela, Maria Leonilde RochaAll rights reserved. Global competition pressures have forced manufactures to adapt their productive capabilities. In order to satisfy the ever-changing market demands many organizations adopted flexible resources capable of executing several products with different performance criteria. The unrelated parallel-machines makespan minimization problem (Rm||Cmax) is known to be NP-hard or too complex to be solved e...
An ordered approach to minimum completion time in unrelated parallel-machines f...
Serra e Santos, Andre; Madureira, Ana Maria; Varela, M.L.R.In the current global market organizations face uncertainties and shorter response time. In order to remain competitive many organizations adopted flexible resources capable of performing several operations with different performance capabilities. The unrelated parallel-machines makespan minimization problem (RmIiCmax) is known to be NP-hard or too complex to be solved exactly. Among the several heuristics used...
Self-optimization module for scheduling using case-based reasoning
Pereira, Ivo; Madureira, Ana MariaMetaheuristics performance is highly dependent of the respective parameters which need to be tuned. Parameter tuning may allow a larger flexibility and robustness but requires a careful initialization. The process of defining which parameters setting should be used is not obvious. The values for parameters depend mainly on the problem, the instance to be solved, the search time available to spend in solving the...
Cooperative scheduling system with emergent swarm based behavior
Madureira, Ana Maria; Pereira, Ivo; Falcão, DiamantinoThis paper presents a Swarm based Cooperation Mechanism for scheduling optimization. We intend to conceptualize real manufacturing systems as interacting autonomous entities in order to support decision making in agile manufacturing environments. Agents coordinate their actions automatically without human supervision considering a common objective – global scheduling solution taking advantages from collective b...
A user-centered interface for scheduling problem definition
Piairo, Jesus; Madureira, Ana Maria; Pereira, João P.; Pereira, IvoIn this paper we present a user-centered interface for a scheduling system. The purpose of this interface is to provide graphical and interactive ways of defining a scheduling problem. To create such user interface an evaluation-centered user interaction development method was adopted: the star life cycle. The created prototype comprises the Task Module and the Scheduling Problem Module. The first one allows us...
