In this presentation, I will defend the need of dedicated semantics and a modeling language to model problem spaces. First, I will show that existing modeling languages, focused on modeling systems, fail to capture fundamental aspects of problems or do so by committing critical mistakes in problem definition. Then, I will present a summary of existing directions to modeling in the problem domain. I will finish my presentation with some ideas of future work that may help us reach the same maturity in problem modeling that we have today in system modeling.
Dr. Alejandro Saladohas over 15 years of experience as a systems engineer, consultant, researcher, and instructor. He is currently an associate professor of systems engineering with the Department of Systems and Industrial Engineering at the University of Arizona. In addition, he provides part-time consulting in areas related to enterprise transformation, cultural change of technical teams, systems engineering, and engineering strategy. Alejandro conducts research in problem formulation, design of verification and validation strategies, model-based systems engineering, and engineering education. Before joining academia, he held positions as systems engineer, chief architect, and chief systems engineer in manned and unmanned space systems of up to $1B in development cost. He has published over 100 technical papers, and his research has received federal funding from the National Science Foundation (NSF), the Naval Surface Warfare Command (NSWC), the Naval Air System Command (NAVAIR), and the Office of Naval Research (ONR), among others. He is a recipient of the NSF CAREER Award, the International Fulbright Science and Technology Award, the Omega Alpha Association’s Exemplary Dissertation Award, and several best paper awards. Dr. Salado holds a BS/MS in electrical and computer engineering from the Polytechnic University of Valencia, a MS in project management and a MS in electronics engineering from the Polytechnic University of Catalonia, the SpaceTech MEng in space systems engineering from the Technical University of Delft, and a PhD in systems engineering from the Stevens Institute of Technology. Alejandro is a member of INCOSE and a senior member of IEEE and AIAA.
