Fuzzy Multi-Objective Optimization
1997Many features of real-life single-objective optimization problems are imprecise. The values of the coefficients are sometimes merely prototypical, the requirement that the constraints must be satisfied may be somewhat relaxed, and the decision makers are not always very satisfied with the value attained by the objective function.

An interactive fuzzy multi-objective optimization method for engineering design
Engineering Applications of Artificial Intelligence, 2006Abstract The coupling of performance functions due to common design variables and uncertainties in an engineering design process will result in difficulties in optimization design problems, such as poor collaboration among design objectives and poor resolution of design conflicts.

A multi-objective evolutionary approach for fuzzy optimization in production planning
Journal of Intelligent & Fuzzy Systems, 2013In this paper we propose a multi-objective optimization approach to solve nonlinear fuzzy optimization problems. Solutions in the Pareto front correspond with the fuzzy solution of the former fuzzy problem expressed in terms of the group of three parameters (x*, μ, α), i.e., optimal solution - degree of satisfaction - vagueness factor.

Evolutionary multi-objective optimization for evolving hierarchical fuzzy system
2015 IEEE Congress on Evolutionary Computation (CEC), 2015In this paper, a Multi-Objective Extended Genetic Programming (MOEGP) algorithm is developed to evolve the structure of the Hierarchical Flexible Beta Fuzzy System (HFBFS). The proposed algorithm allows finding the best representation of the hierarchical fuzzy system while trying to attain the desired balance of accuracy/interpretability.

Multi-objective Portfolio Optimization Based on Fuzzy Genetic Algorithm
2013 Ninth International Conference on Computational Intelligence and Security, 2013Based on the Markowitz portfolio model, this paper considered the liquidity of the risk assets, set the minimum expected return rate of investors, and changed the inequality constraint to semi-gradient fuzzy number. Then used the penalty factor to adjust the objective function, taking the maximum liquidity and minimum risk of portfolio as the ...

A fuzzy multi-objective optimization approach for treated wastewater allocation
Environmental Monitoring and Assessment, 2019In face of the new climate and socio-environmental conditions, conventional sources of water are no longer reliable to supply all water demands. Different alternatives are proposed to augment the conventional sources, including treated wastewater. Optimal and objective allocation of treated wastewater to different stakeholders through an optimization ...
