Jörgen Möller, MSc, is Vice President, Modeling Technologies with Evidera in London, UK. He specializes in simulating complex systems and played a key role in simulating the re-design of the Swedish national postal distribution system, the extension of Stockholm-Arlanda Airport, and the utilization of surgical theatres at Eskilstuna Hospital. Intrigued by the dearth of simulation in pharmacoeconomics and outcomes research, Mr. Möller joined Caro Research in 2003 as a specialist in discrete event simulation (DES) and has been instrumental in implementing DES as a modeling tool in medicine. His focus has been on translating methods from operations research to pharmacoeconomics and on developing guidelines for this type of modeling. Mr. Möller has created more than a dozen DES models in the areas of devices and pharmaceuticals. He also conducts advanced training courses in DES and the ARENA-software. Mr. Möller received an MSc-degree in mechanical engineering at Lund University, Sweden.
