Performance-based multi-objective optimization of large steel structures

Multi-objective Optimization of Product Life-Cycle Costs and Environmental Impacts

“…Hinow and Mevissen [9] use genetic algorithm to optimize LCC of a substation, improving the maintenance activities. In Kaveh et al [10] genetic algorithms, exactly NSGA-2, is used to perform a multi-objective optimization of LCC and initial costs of large steel structures. Here it is possible to see the strong trade-off between initial costs and life cycle costs.…”

Application of endurance time method in performance-based optimum design of structures

“…A more comprehensive decision making study on design alternatives may be achieved by the use of multi-objective optimization procedures and resultant Pareto optimal design alternatives. Multi-objective optimum seismic design has been utilized by various researchers [13][14][15][16]. Life cycle and initial costs are introduced as optimization objectives in most of these researches.…”

“…Liu et al [18] used a robust performance based design approach for a multi-objective optimization using genetic algorithm subjected to uncertainties and provided a set of Pareto optimal designs. Commonly, evolutionary algorithms are employed to solve structural optimization problems owing to their complexity [16]. In this study, NSGA-II [19] is used for solving the defined multi-objective optimization problem.…”

Application of Multi-objective Charged System Search Algorithm for Optimization Problems

“…Many realistic problems contain simultaneous optimization of several objectives in which these objectives may conflict with each other and with other nonlinear constraints, if exist [1][2][3][4][5][6][7]. These types of problems are known as Multi-Objective Problems (MOPs).…”
