Inversion of perturbed linear operators that are singular at the origin

Abstract: We consider the inversion of perturbed linear operators on Hubert space. Namely, we study linear operators that depend on a small parameter and are singular when the parameter is equal to zero. First we consider the affine dependence on the parameter. We treat subsequently the cases of bounded operators with closed range, bounded operators with non closed range, and densely defined and closed unbounded operators. Then, we extend the results to the cases of polynomial and analytic perturbations.

A simulated annealing approach for redesigning a warehouse network problem

Abstract: Now a day, several companies consider downsizing their distribution networks in ways that involve consolidation or phase-out of some of their current warehousing facilities due to the increasing competition, mounting cost pressure and taking advantage on the economies of scale Consequently, the changes on economic situation after a certain period of time require an adjustment on the network model in order to get the optimal cost under the current economic conditions This paper aimed to develop a mixed-integer linear programming model for a two-echelon warehouse network redesign problem with capacitated plant and uncapacitated warehouses The main contribution of this study is considering capacity constraint for existing warehouses A Simulated Annealing algorithm is proposed to tackle with the proposed model The numerical solution showed the model and method of solution proposed was practical
