A new sufficient condition for optimal impulsive control problems
In this article we introduce the concept of MP-pseudoinvexity for general nonlinear impulsive optimal control problems whose dynamics are specified by measure driven control equations. This is a general paradigm in that, ...
An approach for solving interval optimization problems
This work considers an optimization problem where the objective function possesses interval uncertainty in the coefficients. In this sense, first, an order relation will be defined for the interval space and, from this, ...
An analytical solution to the optimal power flow
This letter presents an approach for a geometrical solution of an optimal power flow (OPF) problem for a two-bus system (slack and PV busses). The algebraic equations for the calculation of the Lagrange multipliers and for ...
A hybrid image restoration algorithm based on Projections onto Convex Sets and Harmony Search
Image restoration is a research field that attempts to recover a blurred and noisy image. Since it can be modeled as a linear system, we propose in this paper to use the meta-heuristics optimization algorithm Harmony Search ...
Characterization of robust solutions of multi-objetive optimization models with uncertain weights: applications in a sawmill
The use of weights in multi-objective problems is one of the simplest ways to include multiple criteria in optimization models, in what is known as a weighted-sum approach. However, the solution to these models is highly ...

A mixed-integer LP model for the optimal allocation of voltage regulators and capacitors in radial distribution systems
This paper presents a mixed-integer linear programming model to solve the problem of allocating voltage regulators and fixed or switched capacitors (VRCs) in radial distribution systems. The use of a mixed-integer linear ...
On the properness of an impulsive control extension of dynamic optimization problems
(Edp Sciences S A, 2015-07-01)
This article investigates the properness, or well-posedness, of impulsive extension of a conventional optimal control problem. This includes both well-posedness of the solution to impulsive control systems arising as result ...
Localization of the optimal solution and a posteriori bounds for aggregation
(Elsevier B.V., 1999-09-01)
After an aggregated problem has been solved, it is often desirable to estimate the accuracy loss due to the fact that a simpler problem than the original one has been solved. One way of measuring this loss in accuracy is ...
