This paper proposes an agent-based hybrid tabu-search heuristic (AB-TSH) to solve dynamic flexible job-shop scheduling problems. The solution is fully implemented and tested in an industrial environment for seven distinct dynamic scenarios derived from a static scenario using the benchmark of AIP-PRIMECA Flexible Manufacturing System.
This paper shows how an inverse fuzzy model optimized by a genetic algorithm (GA) can improve the control of an OWC and, consequently, its performance. As a case study, the Mutriku power plant with a biradial turbine was addressed, considering 11 different sea states of the characteristic wave climate.
The Mutriku wave power plant (Spain) was case-studied for evaluating the control approaches, which focused on maximizing average power (turbine or generator) from an OWC equipped with the innovative biradial turbine. In comparison to the reference baseline strategy, the implementation of MPC (with a 16-second forecast) resulted in a minor 2%-increase in the average turbine power.
Many-objective optimization applied to the joint problem of inventory management and restocking policy. A case study on a pharmaceutical company is presented.
A Least Squares Support Vector Machine (LS-SVM) algorithm was developed to predict the air chamber pressure and compare it to the real signal. Regressive linear algorithms were executed for reference. The experimental data was obtained at the Mutriku wave power plant in the Basque Country, Spain.
The problem of scheduling uninterruptible shiftable devices is addressed from a multiagent perspective considering two different approaches. On one hand, a centralized architecture assumes that a single agent has the capacity to solve all agents problems. On the other, a new partially decentralized architecture is proposed to solve the same problem by distributing decision-making among agents using an heuristic algorithm with a virtual dynamic tariff as coordination mechanism.

This work presents a novel formulation for quality control laboratory scheduling considering both equipment and analysts as constraints.
This paper proposes a prediction model based on preoperative characteristics, in order to support the decision of co-management of surgical patients in the postoperative ward setting. The model is a simple bedside decision tool that uses only four numerical variables.
This paper is a review of literature with an analysis on a selection of scientific studies for detection of non-technical losses. Non-technical losses occurring in the electric grid at level of transmission or of distribution have negative impact on economies, affecting utilities, paying consumers and states.
