Piecewise Linear Function Fitting via Mixed-Integer Linear Programming

open access: yesINFORMS Journal on Computing, 2020
Piecewise linear (PWL) functions are used in a variety of applications. Computing such continuous PWL functions, however, is a challenging task. Software packages and the literature on PWL function fitting are dominated by heuristic methods. This is true for both fitting discrete data points and continuous univariate functions.

Repetitive construction processes scheduling using mixed-integer linear programming

open access: yesBudownictwo i Architektura, 2015
Many construction projects contain several identical or similar units, such as floors in multistory buildings, houses in housing developments, sections of pipelines or highways.

Polyhedral Approaches to Mixed Integer Linear Programming [PDF]

open access: yes, 2009
This survey presents tools from polyhedral theory that are used in integer programming. It applies them to the study of valid inequalities for mixed integer linear sets, such as Gomory's mixed integer cuts.

Proximity search heuristics for wind farm optimal layout [PDF]

open access: yes, 2015
A heuristic framework for turbine layout optimization in a wind farm is proposed that combines ad-hoc heuristics and mixed-integer linear programming.

Analyzing Infeasible Mixed-Integer and Integer Linear Programs [PDF]

open access: yesINFORMS Journal on Computing, 1999
Algorithms and computer-based tools for analyzing infeasible linear and nonlinear programs have been developed in recent years, but few such tools exist for infeasible mixed-integer or integer linear programs. One approach that has proven especially useful for infeasible linear programs is the isolation of an Irreducible Infeasible Set of constraints (

Application-oriented mixed integer non-linear programming [PDF]

open access: yes4OR, 2010
In the most recent years there is a renovate interest for Mixed Integer Non-Linear Programming (MINLP) problems. This can be explained for different reasons: (i) the performance of solvers handling non-linear constraints was largely improved; (ii) the awareness that most of the applications from the real-world can be modeled as an MINLP problem; (iii ...

Combinatorial Benders' Cuts for Mixed-Integer Linear Programming [PDF]

open access: yesOperations Research, 2006
Mixed-integer programs (MIPs) involving logical implications modeled through big-M coefficients are notoriously among the hardest to solve. In this paper, we propose and analyze computationally an automatic problem reformulation of quite general applicability, aimed at removing the model dependency on the big-M coefficients.

Valid inequalities for mixed integer linear programs [PDF]

open access: yesMathematical Programming, 2007
This tutorial presents a theory of valid inequalities for mixed integer linear sets. It introduces the necessary tools from polyhedral theory and gives a geometric understanding of several classical families of valid inequalities such as lift-and-project cuts, Gomory mixed integer cuts, mixed integer rounding cuts, split cuts and intersection cuts, and

A simulation-optimization approach for integrating physical and financial flows in a supply chain under economic uncertainty

open access: yesOperations Research Perspectives, 2023
In the last decade, increasing costs and organizational concerns regarding the funding and allocation of financial resources have led to significant attention being given to financial flow and its effects on planning decisions throughout supply chain ...

Energy System Optimization Using (Mixed Integer) Linear Programming

open access: yes, 2023
Although energy system optimisation based on linear optimisation is often used for influential energy outlooks and studies for political decision-makers, the underlying background still needs to be described in the scientific literature in a concise and general form.
