Energy–Water Management System Based on MPC for a Greenhouse in a Mapuche Indigenous Community

open access: yesApplied Sciences, 2023
Rural communities usually settle in territories where crop self-consumption is the main source of sustenance. In this context, climate change has made these environments of crop control susceptible to water shortages, impacting crop yields.

New Class of Preinvex Fuzzy Mappings and Related Inequalities

open access: yesMathematics, 2022
This study aims to consider new kinds of generalized convex fuzzy mappings (convex-𝘍𝘔), which are called strongly α-preinvex fuzzy mappings. We investigated the characterization of preinvex-𝘍𝘔s using α-preinvex-𝘍𝘔s, which can be viewed as a novel and ...

A Spinning Reserve Allocation Method for Power Generation Dispatch Accommodating Large-Scale Wind Power Integration

open access: yesEnergies, 2013
Spinning reserve allocation is a critical problem for active power dispatch with large-scale wind power penetration. A risk-based reserve allocation method that accounts multiple control sub-area coordination is given in this paper. And a multi-objective

Variational-like inequalities for n-dimensional fuzzy-vector-valued functions and fuzzy optimization

open access: yesOpen Mathematics, 2019
The existing results on the variational inequality problems for fuzzy mappings and their applications were based on Zadeh’s decomposition theorem and were formally characterized by the precise sets which are the fuzzy mappings’ cut sets directly. That is,

OPTIMIZATION ISSUES FOR FUZZY MEASURES

open access: yesInternational Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 1999
In this paper, we address the problem of identification of fuzzy measures through different representations, namely the Möbius, the Shapley and the Banzhaf interaction representations. In the first part of the paper, we recall the main results concerning these representations, and give a simple algorithm to compute them.
