Modeling issues and implementation of language for disjunctive programming
(Pergamon-Elsevier Science Ltd, 2000-10)
This paper describes a number of key modeling issues for the development of tools for solving nonlinear discrete/continuous problems where logic/disjunctive constraints are included in the formulation. A generalized hybrid ...
Modeling of discrete/continuous optimization problems: Characterization and formulation of disjunctions and their relaxations
(Pergamon-Elsevier Science Ltd, 2003-03-15)
This paper addresses the relaxations in alternative models for disjunctions, big-M and convex hull model, in order to develop guidelines and insights when formulating Mixed-Integer Non-Linear Programming (MINLP), Generalized ...
On the optimal selection and integration of batteries in dc grids through a mixed-integer quadratic convex formulation
(MDPI, 2021-10)
This paper deals with the problem of the optimal selection and location of batteries in DC distribution grids by proposing a new mixed-integer convex model. The exact mixed-integer nonlin-ear model is transformed into a ...
Mixed-integer linear programming approach for product design for life-cycle profit
(Pergamon-Elsevier Science Ltd, 2019-11)
The paper deals with the product design problem where the characteristics of new and remanufactured products must be determined. The objective of the problem is to maximize the total profit taking into account the design ...
