A recognized expert, he led numerous projects in decision-making mathematics and spearheaded the development of the company’s entire range of business components. Author of numerous publications on resource optimization, he continues to teach operations research, notably at École Centrale Paris.
“I enjoy working on a variety of topics. I also appreciate the opportunity to regularly pursue my training.”
“My role is also to define the work areas, roadmaps and development plans in the short, medium and long term, as well as to support the developers on a daily basis.”
Ronan Bars, a graduate of the INSA Rennes engineering school, joined EURODECISION in 1998 and was its Managing Director from 2012 to 2025.
“What motivates me is the fact that we are solving tangible business issues.”
“Over its 15 years, EURODECISION has always adapted to market needs yet its organization has kept its human-scale feel. I’m particularly committed to this company that I have seen expand and in whose environment I have grown.”

A graduate of the Paris Ecole Centrale with a degree in engineering, he also has earned doctorate degrees in applied mathematics and management sciences.
“In a short space of time I have worked on a dozen missions and built up great experience. It’s not what you’d call a humdrum occupation for we handle a variety of topics, in many different lines of business and with contact partners who are poles apart.”
“Customers who call on us look for our expertise in optimization algorithms and complex business issues. During these long term assignments we work in close collaboration with the customer’s team.”
“Now, I manage a team of 7 people. It is a managing role which means organizing individual and team meetings regarding projects follow-ups, discuss customers business issues, share experiences, but also more informal “Department lunches”.”
We work in very various business sectors, even if public transportation is our long-time field of application. Each customers is specific, and we have to show strong business comprehension skills to answer their requests.
