A weak maximum principle for optimal control problems with mixed constraints under a constant rank condition
(2020-09-01)
Necessary optimality conditions for optimal control problems with mixed state-control equality constraints are obtained. The necessary conditions are given in the form of a weak maximum principle and are obtained under (i) ...
A review and evaluation on constructive heuristics to optimise product mix based on the Theory of Constraints
(TAYLOR & FRANCIS LTDABINGDON, 2012)
In this paper, we address the problem of defining the product mix in order to maximise a system's throughput. This problem is well known for being NP-Complete and therefore, most contributions to the topic focus on developing ...
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 ...
When less is better: insights from the product mix dilemma from the Theory of Constraints perspective
(Taylor & FrancisOxfordshire, 2013)
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 ...

Product mix: The approach of throughput per day
(2013-07-03)
Defining product mix is very important for organisations because it determines how productive resources are allocated among various operations. However, it is often defined subjectively. The methods commonly used for this ...
Necessary optimality conditions for minimax optimal control problems with mixed constraints
(2021-01-01)
A weak maximal principle for minimax optimal control problems with mixed state-control equality and inequality constraints is provided. In the formulation of the minimax control problem we allow for parameter uncertainties ...
A Weak Maximum Principle for Optimal Control Problems with Nonsmooth Mixed Constraints
(Springer, 2009-06-01)
We derive a weak Maximum Principle for nonsmooth optimal control problem involving mixed constraints under some convexity assumptions. Notably we consider problems with possibly nonsmooth mixed constraints. A nonsmooth ...
Logically constrained optimal power flow: Solver-based mixed-integer nonlinear programming model
(Elsevier B.V., 2018-04-01)
There is increasing evidence of the shortage of solver-based models for solving logically-constrained AC optimal power flow problem (LCOPF). Although in the literature the heuristic-based models have been widely used to ...
Network-Constrained Multiperiod Auction for Pool-Based Electricity Markets of Hydrothermal Systems
(Ieee-inst Electrical Electronics Engineers Inc, 2017-11-01)
Network-constrained market clearing procedures in pool-based electricity markets of hydropower systems have traditionally neglected the constraints associated with physical and operating aspects of hydroelectric generation ...
