Control and Optimization of Batch Chemical Processes

A batch process is characterized by the repetition of time-varying operations of finite duration. Due to the repetition, there are two independent “time” variables, namely, the run time during a batch and the batch index. Accordingly, the control and optim ...

A process integration method with multiple heat exchange interfaces

François Maréchal, Ivan Daniel Kantor, Hür Ebuzer Bütün

In recent decades, energy efficiency has become one of the key issues facing industrial producers. Mounting economic, environmental and social factors motivate energy-intensive industries to improve their efficiency. Identifying energy saving retrofit oppo ...

Towards optimal design of solar assisted industrial processes: Case study of a dairy

François Maréchal, Anna Sophia Wallerand, Régis Voillat

Pinch analysis is a valuable tool for industrial process integration and optimization. Based on heat cascading and Mixed Integer Linear Programming (MILP) the optimal utility system can be found, includ- ing traditional heat sources (burners, boilers) and ...

What Players do with the Ball: A Physically Constrained Interaction Modeling

Pascal Fua, Xinchao Wang, Andrii Maksai

Tracking the ball is critical for video-based analysis of team sports. However, it is difficult, especially in low resolution images, due to the small size of the ball, its speed that creates motion blur, and its often being occluded by players. In this pa ...

Robust optimization for strategic energy planning

Michel Bierlaire, François Maréchal, Stefano Moret

Long-term planning for energy systems is often based on deterministic economic optimization and forecasts of fuel prices.When fuel price evolution is underestimated, the consequence is a low penetration of renewables and more efficient technologies in favo ...

Multiperiod Sequential Synthesis of Heat Exchanger Networks and Utility Systems including storages

François Maréchal, Alberto Mian, Emanuele Martelli

This work proposes a sequential approach for the multi-period synthesis of Heat Exchanger Networks (HEN) and Utility Systems of chemical processes and energy systems, including thermal, electric and material storage. The optimization approach is sequential ...

Inventory routing with non-stationary stochastic demands

Michel Bierlaire, Sacha Varone, Mohammad Yousef Maknoon, Iliya Dimitrov Markov

We solve a rich logistical problem inspired from practice, in which a heterogeneous fixed fleet of vehicles is used for collecting recyclable waste from large containers over a finite planning horizon. Each container is equipped with a sensor, which commun ...

A new mathematical formulation to integrate supply and demand within a choice-based optimization framework

Michel Bierlaire, Shadi Sharif Azadeh, Meritxell Pacheco Paneque

During the last decade, there has been an increasing trend to combine customer behavior models in optimization, since it provides a better understanding of the preferences of clients to policy makers while planning for their systems. These preferences are ...
