Heterogeneous effects of financial constraints on innovation: Evidence from Chile
(Oxford University Press, 2015)
In this paper we study the effect of financial constraints on innovation using data from a 2007 survey of more than 10,000 Chilean firms. In contrast with other surveys, this dataset allows for the construction of a direct ...
Optimized harvest scheduling in eucalyptus plantations under operational, spatial and climatic constraints
(IPEF-INST PESQUISAS ESTUDOS FLORESTAIS, 2010)
The representation of sustainability concerns in industrial forests management plans, in relation to environmental, social and economic aspects, involve a great amount of details when analyzing and understanding the ...
On the solution of mathematical programming problems with equilibrium constraints
(2002-02-01)
Mathematical programming problems with equilibrium constraints (MPEC) are nonlinear programming problems where the constraints have a form that is analogous to first-order optimality conditions of constrained optimization. ...

Mathematical programming problems with equilibrium constraints (MPEC) are nonlinear programming problems where the constraints have a form that is analogous to first-order optimality conditions of constrained optimization. ...
Influence of the Operational Constraints in the Active Transmission Losses Allocation via Lagrange Multipliers
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
This paper presents an approach for the active transmission losses allocation between the agents of the system. The approach uses the primal and dual variable information of the Optimal Power Flow in the losses allocation ...
Proposta de aplicação da teoria das restrições no processo de beneficiamento do arroz
(Universidade Tecnológica Federal do ParanáMedianeira, 2011-12-05)
In recent years companies have faced strong pressure from competition, thus seeking new alternatives for management. Thus this study presents a proposal to apply the process of continuous improvement displayed by the ...
A proposal for a theory of constraints-based framework in sales and operations planning
(2021-04-29)
Research indicates that there is a lack of studies of the application of the concepts and assumptions, their effects, contributions and limitations for long-term planning of the theory of constraints (TOC). In this sense, ...
Imposing Radiality Constraints in Distribution System Optimization Problems
(Institute of Electrical and Electronics Engineers (IEEE), 2012-02-01)
Distribution systems commonly operate with a radial topology, so all models of optimization problems in these distribution systems should consider radiality in their formulation. This work presents a literature review, a ...
Analysis of the radial operation of distribution systems considering operation with minimal losses
(Elsevier B.V., 2015-05-01)
Electric power distribution systems, and particularly those with overhead circuits, operate radially but as the topology of the systems is meshed, therefore a set of circuits needs to be disconnected. In this context the ...
