A multi-objective optimization method was developed for the design of trigeneration plants. The optimization is carried out on technical, economical, energetic and environmental performance indicators in a multi-objective optimization framework. Both construction (equipment sizes) and discrete...

The transformer is one of the most useful pieces of equipment in a power system. The objective of the optimum design is to build the equipment as economically as possible. The design which fulfils certain limitations is subordinated to the question of economic manufacture. This paper presents a...

In this paper we present a Feed-Foward Neural Networks Autoregressive (FFNN-AR) model with genetic algorithms training optimization in order to predict the gross domestic product growth of six countries. Specifically we propose a kind of weighted regression, which can be used for econometric...
