We propose mathematical programming models for solving problems arising from planning and running an energy production process based on burning biomasses. The models take into account different aspects of the problem: determination of the biomasses to produce and/or buy, transportation decisions to convey the materials to the respective plants, and plant design. Whereas the “running model” is l...

A conic integer program is an integer programming problem with conic constraints.Manyproblems infinance, engineering, statistical learning, andprobabilistic optimization aremodeled using conic constraints. Herewe studymixed-integer sets definedby second-order conic constraints.We introduce general-purpose cuts for conic mixed-integer programming based on polyhedral conic substructures of second...

This paper presents a new algorithm for solving mixed integer nonlinear programming problems. The algorithm uses a branch and bound strategy where a nonlinear programming problem is solved in each integer node of the tree. The nonlinear programming problems, at each integer node of the tree, are not solved to optimality, rather one iteration step is taken at each node and then linearizations of...

Energy disaggregation, known in the literature as Non-Intrusive Load Monitoring (NILM), is task of inferring energy consumption each appliance given aggregate signal recorded by a single smart meter. In this paper, we propose novel two-stage optimization-based approach for disaggregation. first phase, small training set consisting disaggregated power profiles used to estimate parameters and sta...
