In recent years, renewable energy sources such as wind energy have been used as one of the most effective ways to reduce pollution emissions. In this paper, a summation based multi-objective differential evolution (SMODE) algorithm is used to optimize the economic emission dispatch problem with stochastic wind power. The Weibull probability distribution function is used to model the stochastic ...

Portfolio optimization context has shed only a little light on the dependence structure among the financial returns along with the fat-tailed distribution associated with them. This study tries to find a remedy for this shortcoming by exploiting stable distributions as the marginal distributions together with the dependence structure based on copula function. We formulate the portfolio optimiza...

Model-Driven Engineering (MDE) aims at raising the level of abstraction in software development and therefore relies on task automation. To foster automation, MDE promotes the use of specific domain languages (DSLs), essential to express ideas at the domain level. Furthermore, to ease communication between computer science and other fields, modelers employ model examples (i.e., selected metamod...

RÉSUMÉ. In this paper, we present a global optimisation method based on a multi-objective Genetic Algorithm (GA) for the design of filter banks in a lossy image coding scheme. To be effective, the filter banks should satisfy a number of desirable criteria related to such scheme. We formulate the optimization problem as multi-objective and we use the Non-dominated Sorting Genetic Algorithm appro...

The sailor assignment problem is a classic example of the generalized task assignment problem. In this instance, it is tried to assign the optimum tasks to the sailors in various time intervals according to their skills, experience and their location with different workloads. This problem has numerous applications in real world however due to many constraints and targets; the solution is not st...

Received Jan 24, 2017 Revised May 4, 2017 Accepted Jun 10, 2017 In recent decades, one of the main management’s concerns of professional engineers is the optimal integration of various types of renewable energy to the grid. This paper discusses the optimal allocation of one type of renewable energy i.e. wind turbine to the grid for enhancing network’s performance. A multi-objective function is ...

Many-objective optimization refers to optimization problems with a number of objectives considerably larger than two or three. In this paper, a study on the performance of the Fast Elitist Non-dominated Sorting Genetic Algorithm (NSGA-II) for handling such many-objective optimization problems is presented. In its basic form, the algorithm is not well suited for the handling of a larger number o...

Decision makers must face the dynamism and uncertainty of real-world environments when they need to solve the scheduling problems. Different incidences or breakdowns, for example, initial data could change or some resources could become unavailable, may eventually cause the infeasibility of the obtained schedule. To overcome this issue, a robust model and a proactive approach are presented for ...

Test problems have played a fundamental role in understanding the strengths and weaknesses of the existing Evolutionary Multiobjective Optimization (EMO) algorithms. A range of test problems exist which have enabled the research community to understand how the performance of EMO algorithms is affected by the geometrical shape of the Pareto front (PF), i.e., PF being convex, concave or mixed. Ho...
