When less is better: Insights from the product mix dilemma from the Theory of Constraints perspective
(2013-07-03)
Perhaps due to its origins in a production scheduling software called Optimised Production Technology (OPT), plus the idea of focusing on system constraints, many believe that the Theory of Constraints (TOC) has a vocation ...
A Linear Approximation Model for a Non-Linear Flow Shop Scheduling Problem with Learning Effect
(Balikesir University, 2021)
Learning effects have been considered in operations management problems since the early twentieth century [1]. The learning effect has a direct influence on production scheduling problems, since it modifies the use of ...
A constructive heuristic algorithm for multi-stage transmission expansion planning under N-1 security constraints
(2015-04-01)
The transmission expansion planning (TEP) problem in modern power systems is a large-scale, mixed-integer, non-linear, and non-convex problem. The problem becomes even more complicated when the security constraints are ...
A multiperiod model for production planning and design in a multiproduct batch environment
(Pergamon-Elsevier Science Ltd, 2009-04)
A general multiperiod model to optimize simultaneously production planning and design decisions applied to multiproduct batch plants is proposed. This model includes deterministic seasonal variations of costs, prices, ...
Var Planning Problem Considering Conditional Value-at-Risk Assessment
(Ieee, 2014-01-01)
This paper presents the reactive power planning solution under risk assessment through the CVaR (Conditional-Value-at-Risk) using stochastic programming. Load uncertainty is modeled by distribution function. Uncertainty ...

Programação linear inteira mista aplicada na proteção adaptativa de sobrecorrente direcional considerando contingência n-1
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2022-03-29)
This work presents a methodology for adjusting and coordinating overcurrent protection in
interconnected transmission systems considering a possible network contingency state. For the
protection parameterization, the ...
Feature selection for Support Vector Machines via Mixed Integer Linear Programming
(Elsevier, 2014)
The performance of classification methods, such as Support Vector Machines, depends
heavily on the proper choice of the feature set used to construct the classifier. Feature
selection is an NP-hard problem that has been ...
Interactive system for placement and coordination of overcurrent protective devices
(2006-12-01)
In this paper, an expert and interactive system for developing protection system for overhead and radial distribution feeders is proposed. In this system the protective devices can be allocated through heuristic and an ...
