Abstract:This work is concerned with the efficient allocation of trucks to shovels in operation at open-pit mines. As this problem involves high-value assets, namely mining trucks and shovels, any improvement obtained in terms of operational efficiency can result in considerable financial savings. Thus, this work presents multi-objective strategies for solving the problem of dynamically allocating a heterogeneous fleet of trucks in an open-pit mining operation, aiming at maximizing production and minimizing costs, subj… Show more
“…A neuro-evolutive algorithm (NEA) is among the evolutionary algorithms (EAs) used in the design and/or training of an artificial neural network (ANN). Bio-inspired Algorithms (BIOAs) have gained popularity due to their efficiency at solving different non-linear optimization problems [5]. In this context, this paper tests the possibilities of a hybrid system called Artificial Development and Evolution of Deep Neural Networks (ADEANN-Deep) for shor-term energy price prediction using explanatory variables.…”
The aim of this paper is to introduce a biologically inspired approach that can automatically generate Deep Neural networks with good prediction capacity, smaller error and large tolerance to noises. In order to do this, three biological paradigms were used: Genetic Algorithm (GA), Lindenmayer System and Neural Networks (DNNs). The final sections of the paper present some experiments aimed at investigating the possibilities of the method in the forecast the price of energy in the Brazilian market. The proposed model considers a multi-step ahead price prediction (12, 24, and 36 weeks ahead). The results for MLP and LSTM networks show a good ability to predict peaks and satisfactory accuracy according to error measures comparing with other methods.
