From Computer-Aided Drafting to Knowledge Supported Cooperative Design
Jean-Paul Barthes, Université de Technologie de Compiègne, France

The presentation will brief overview of the domain, also reviewing the history of CSCWD and ISMICK for which we are gathered at Lausanne. CSCWD started at a time when people were more interested in tools than in the design process itself, although one already talked of Knowledge Intensive Design. At the same epoch ISMICK was started one of the goal being of using knowledge throughout the lifecycle of complex new products. Today, both approaches converge and it is difficult to talk about design without taking into account the product lifecycle and the associated knowledge. After reviewing briefly the changes that occured in the two domains during the last twenty years, I will describe a project that aims at combining both approaches for the phase of conceptual preliminary design. It certainly needs much more research to become an industrial reality.

Jean-Paul Barthès was born in France, on July 9, 1945. He graduated from the École Centrale des Arts et Manufactures, Paris, and obtained a PhD degree from the University of Stanford, USA. His employment experience included the Société Générale pour les Techniques Nouvelles, a branch of the nuclear industry, in Paris, and the Université de Technologie de Compiègne. His special fields of interest include artificial intelligence, knowledge representation, and multi-agent systems. Prof. Barthès developed a number of software systems including MOSS, a knowledge representation system, an object database that led to the MATISSE™ product and several multi-agent platforms, in particular, a multi-agent platform, OMAS, for developing systems of cognitive agents.

Cooperation and cooperative design for a new automotive engine in the Renault Group
Jean-Louis Ligier, Renault Group, France

To develop a new engine, many contributors are involved in the design process, particularity when the car manufacturer is an international company. The presentation will give in a first part an overview on cooperation between various Renault members. After a description of main difficulties to exchange, we will focus on the main keys to success. A second part will be dedicated to the internal collaborative works within Renault corporate. It will be related to the different physical area which define or constrain the engine design. As a new engine is the results of many optimizations between different domains of physics, the process to get these optimizations will be described. Some focus will be given on the main difficulties encountered to get cooperative design. To finish, perspective on improvement will be mentioned.

Jean-Louis Ligier obtained, after graduating from French engineering school, a PhD dedicated to asymptotic method for homogenization techniques in 1986. He has spent more than 20 years in automotive companies mainly as simulation department manager and is currently expert in this field. Up to now, his experience is focused on simulation for automotive engine design. Main points of interest are analysis and computer simulation on thermo-mechanics dynamics and lubrication analysis. In parallel with this industrial job, more than 60 papers have been published in these different fields, in addition to four books related to lubrication, vibration and bearing damage.

Human and Judgemental Factors in Collaborative Demand Forecasting
Naoufel Cheikrouhou, EPFL, Switzerland

So far, human factors in industrial environments have been considered from the safety perspective. However, beyond this specific field, it has been the need to address human factors as an important element impacting decisions in Operations Management. Within this frame, the talk addresses the research status on identifying, modelling and integrating human factors in Operations Management. The talk is supported by results from case studies and current work on the development of demand forecasting techniques. Indeed, we present a collaborative judgemental approach for demand forecasting in which the mathematical forecasts are adjusted by a structured technique that combines knowledge from different forecasters. The approach is based on the identification and classification of four types of judgemental events. Factors corresponding to these events are evaluated through a fuzzy inference system to ensure the coherence and the consistency of the collaborative aspect of the technique.

Dr. Naoufel Cheikhrouhou is the head of the Operations Management group at the Swiss Federal Institute of Technology at Lausanne (EPFL). After graduation from the Ecole Nationale d'Ingenieurs de Tunis in 1995, he obtained a PhD in Industrial Engineering from the Institut National Polytechnique de Grenoble. His main research interests are modelling, simulation and optimisation of entreprise networks and integration of human factors in Operations Management, for which he received the Burbidge Award in 2003. Leading different projects with the collaboration of industrial as well as academic partners, Dr. Cheikhrouhou contributed to the emergence of new software solutions in the areas of ERP and Supply chain Planning, such as Acteos PPS or Proconcept ERP.
