A bi-integrated model for coupling lot-sizing and cutting-stock problems
Amanda O. C. Ayres, Betania S. C. Campello, Washington A. Oliveira +1
In this paper, a framework that addresses the core of the papermaking process is proposed, starting from the production of jumbos and ending with the paper sheets used in daily lif…
Packing circles within circular containers: a new heuristic algorithm for the balance constraints case
Washington Alves de Oliveira, Luiz Leduino de Salles Neto, Antonio Carlos Moretti +1
In this work we propose a heuristic algorithm for the layout optimization for disks installed in a rotating circular container. This is a unequal circle packing problem with additi…
Local Pareto optimality conditions for vector quadratic fractional optimization problems
Washington A. Oliveira, Marko A. Rojas Medar, A. Beato Moreno +1
There are several concepts and definitions that characterize and give optimality conditions for solutions of a vector optimization problem. One of the most important is the first-o…
Pareto optimality conditions and duality for vector quadratic fractional optimization problems
Washington Alves de Oliveira, Antonio Beato Moreno, Antonio Carlos Moretti +1
One of the most important optimality conditions to aid to solve a vector optimization problem is the first-order necessary optimality condition that generalizes the Karush-Kuhn-Tuc…
The multi-vehicle covering tour problem: building routes for urban patrolling
Washington Alves de Oliveira, Antonio Carlos Moretti, Ednei Felix Reis
In this paper we study a particular aspect of the urban community policing: routine patrol route planning. We seek routes that guarantee visibility, as this has a sizable impact on…
