He, K. (author), Shi, S. (author), van den Boom, A.J.J. (author), De Schutter, B.H.K. (author)Approximate dynamic programming (ADP) faces challenges in dealing with constraints in control problems. Model predictive control (MPC) is, in comparison, well-known for its accommodation of constraints and stability guarantees, although its computation is sometimes prohibitive. This paper introduces an approach combining the two methodologies...journal article 2024

An MPC-Based Rescheduling Algorithm for Disruptions and Disturbances in Large-Scale Railway NetworksCavone, Graziana (author), van den Boom, A.J.J. (author), Blenkers, Lex (author), Dotoli, Mariagrazia (author), Seatzu, Carla (author), De Schutter, B.H.K. (author)Railways are a well-recognized sustainable transportation mode that helps to satisfy the continuously growing mobility demand. However, the management of railway traffic in large-scale networks is a challenging task, especially when both a major disruption and various disturbances occur simultaneously. We propose an automatic rescheduling...journal article 2022

Segovia Castillo, P. (author), Pesselse, Mike (author), van den Boom, A.J.J. (author), Reppa, V. (author)This paper considers the inland waterborne transport (IWT) problem, and presents a scheduling approach for inland vessels and locks to generate optimal vessel and lock timetables. The scheduling strategy is designed in the switching max-plus-linear (SMPL) systems framework, as these are characterized by a number of features that make them...journal article 2022

Koppen, S. (author), van der Kolk, M. (author), van den Boom, S.J. (author), Langelaar, Matthijs (author)Real-world structural optimisation problems involve multiple loading conditions and design constraints, with responses typically depending on states of discretised governing equations. Generally, one uses gradient-based nested analysis and design approaches to solve these problems. Herein, solving both physical and adjoint problems dominates...journal article 2022

Gupta, A. (author), van den Boom, A.J.J. (author), van der Woude, J.W. (author), De Schutter, B.H.K. (author)We introduce a framework for studying controllability properties of discrete-event systems modelled as switching max-plus linear systems. In this framework, we generalise the notion of structural controllability to include the switching phenomenon. Such models provide an additional discrete input to change the synchronisation and/or ordering...journal article 2020

van den Boom, A.J.J. (author), Muijsenberg, Marenne van den (author), De Schutter, B.H.K. (author)In this paper we discuss scheduling of semi-cyclic discrete-event systems, for which the set of operations may vary over a limited set of possible sequences of operations. We introduce a unified modeling framework in which different types of semi-cyclic discrete-event systems can be described by switching max-plus linear (SMPL) models. We use...journal article 2020

De Schutter, B.H.K. (author), van den Boom, A.J.J. (author), Xu, J. (author), Safaei Farahani, S. (author)The objective of this paper is to provide a concise introduction to the max-plus algebra and to max-plus linear discrete-event systems. We present the basic concepts of the max-plus algebra and explain how it can be used to model a specific class of discrete-event systems with synchronization but no concurrency. Such systems are called max...journal article 2020

van den Boom, A.J.J. (author), Bruijn, Hilco de (author), De Schutter, B.H.K. (author), Özkan, Leyla (author)In this paper a new iterative approach is proposed for the design of a combined real-time scheduling and control algorithm that can be applied to industrial systems that are described by a hybrid model with a (semi-)cyclic behavior. Traditionally scheduling and control problems are considered in a sequential way. First the scheduling problem...journal article 2018

Luan, X. (author), De Schutter, B.H.K. (author), van den Boom, A.J.J. (author), Corman, F. (author), Lodewijks, G. (author)We introduce a distributed optimization method for improving the computational efficiency of real-time traffic management approaches for large-scale railway networks. We first decompose the whole network into a pre-defined number of regions by using an integer linear optimization approach. For each resulting region, a mixed-integer linear...journal article 2018

Xu, J. (author), van den Boom, A.J.J. (author), Busoniu, L (author), De Schutter, B.H.K. (author)This paper considers model predictive control for continuous piecewise affine (PWA) systems. In general, this leads to a nonlinear, nonconvex optimization problem. We introduce an approach based on optimistic optimization to solve the resulting optimization problem. Optimistic optimization is based on recursive partitioning of the feasible set...conference paper 2016

Receding-horizon control for max-plus linear systems with discrete actions using optimistic planningXu, J. (author), Busoniu, L (author), van den Boom, A.J.J. (author), De Schutter, B.H.K. (author)This paper addresses the infinite-horizon optimal control problem for max-plus linear systems where the considered objective function is a sum of discounted stage costs over an infinite horizon. The minimization problem of the cost function is equivalently transformed into a maximization problem of a reward function. The resulting optimal...conference paper 2016
