Comment mettre la modélisation mathématique au service de la prise de décision en entreprise ?

Conférence Plénière :
Orateurs : Benoît Roland et Jean-François Peters, n-SIDE, Belgique
Résumé : n-Side est une société de consultance belge qui a pour mission d'aider les top managers de sociétés industrielles à prendre de meilleures décisions face à des problématiques technico-économiques complexes. L’approche proposée par n-Side est unique en son genre car elle repose essentiellement sur des techniques de Recherche Opérationnelle (RO). Les équipes de n-Side, composées d'ingénieurs et docteurs en mathématiques appliquées, ont développé une expertise approfondie en modélisation et résolution des problèmes clients. Mondialement présente, la société est active dans différents domaines tels que la sidérurgie, l'industrie pharmaceutique, l’énergie, la Supply Chain, le secteur hospitalier et bien d’autres. Les solutions qu’elle développe utilisent des techniques éprouvées de la Recherche Opérationnelle,  comme les modélisations linéaire, entière ou non linéaire, la simulation, les approches heuristiques, la programmation par contraintes, etc. Cette session plénière donnera aux participants un aperçu de différentes applications de la RO à des problèmes métier rencontrés par les clients de n-Side, et des bénéfices que ces derniers en ont retirés. Les orateurs partageront leur point de vue d'experts sur le sujet et souligneront les avantages qu’offre l’utilisation de telles approches dans la pratique managériale courante.

SIMULATION IN PORTS OPERATIONS

Plenary Talk by : Carles Catalán, Associate Partner, Avantsim.

 

Abstract : Simulation is a young and constantly evolving technique through which we can imitate the behavior of any real system. With this tool, which is becoming increasingly relevant and important in the analysis and improvement of systems, we can model very complex processes and simulate reality with all possible variables.

The simulation applied to the port environment allows us to build models that represent different elements of port and terminal operations (container, bulk cargo, cars…etc)  in order to calculate the capacity, dimensions of the equipment and, consequently, optimize the  terminals and to maximize its profit.

What benefits do we get through a dock extension? Is it advisable to invest in the purchase of a new crane? What is the best equipment for this terminal, What is the real need for transfer buffers? How many hours is the equipment employed? What is the dimension of space required for parking trucks,  how many gates of customs, how many tugs, how many dockers ……. These are some of the questions, among many and more complex others, that the simulation system is able to solve in the virtual world before the changes are implemented in reality.

During my professional work I have been working with simulation models for more than a decade. My primary objective is to create models that accurately represent reality and the future of the terminals in order to provide multiple alternatives that offer the best solution to each of the problems we encounter.

When we deal with new terminals, the system allows us to calculate the capacities of the yard, the quayside and access; set dimensions of the terminal; calculate the machinery that is needed and project the ideal operating system according to the characteristics of the traffic and the environment of the terminal. At existing terminals, through simulation we conduct studies of specific elements such as the access, queues of trucks, reefer connections, parking space and the analysis of new requirements based on traffic forecasts. Our goal is the continuous improvement of the overall operational process.

The simulation plays the evolvement of different events based on initial established conditions. The result is a mathematical representation of reality, in which all the significant variables that reflect the new circumstances are defined. For example, the simulation would allow us to calculate the impact of having a contract with a new shipping line, which equipment needs it would cause, how it would affect the terminal as a whole, which berthing windows could be allocated...

The simulation allows economical and reliable changes in a safe environment which, if happened in reality, would imply a high cost, both time and economic. The simulation models represent the entire terminal or some parts of it, while taking into account all the variables of the terminal in order to identify the best solutions.

The transport and logistics sectors are areas of growing interest in simulation techniques. Most of the available tools are not sufficiently complete to solve the problems of coordinating the various factors involved in the handling, loading, discharge and transport of the cargo; factors that have a determining influence on the overall system performance.

In summary, the simulation tools are presently the ideal platform to successfully address the process of continuous improvement in the leading companies in our sector. Improvements to implement for the benefit of the port community members in the ports.

Développement d’une méthodologie de transformation leagile pour le développement de produits de luxe

Conférence animée par : Prof. Lamouri Samir, ENSAM Paris - France
Résumé : Le Lean constitue aujourd’hui une des principales méthodologies d’amélioration de processus. Si beaucoup de travaux de recherche ont été publiés traitant de son application dans des secteurs manufacturiers classiques, ceux qui s’intéressent au Lean Development dans des industries de création comme celle des produits de luxe demeurent inexplorés. Cette industrie est d’ailleurs reconnue comme ayant des processus de conception et de développement longs et hétérogènes et l’utilisation d’une approche lean y demeure questionnable. Cette recherche vise à répondre en partie à cette question en proposant une analyse des spécificités de cette industrie. La contribution principale de cette recherche est de développer une méthodologie de transformation poursuivant des objectifs lean et agiles pour le secteur d’activité de développement des produits de luxe.
