The Modeling and Simulation Profession and its Specializations Bruce Fairchild Lou Birta Bernie Zeigler

Overview A Broad Perspective of M&S into the Future The types of M&S professionals that have/will emerge Summary: Implications for Certification

Discussion of M&S Profession Must Start With Broad Representation of the M&S Enterprise A taxonomic breakdown of an M&S project into its parts: application, objective, techniques, credibility, and programmatic All the phases of System development/use that M&S infrastructure supports A generic structure or conceptual architecture in which the various activities/resources of M&S are presented in an orderly manner The various applications domains in which the generic structure appears in specialized form and often only partially realized

Within this comprehensive view, there are many specializations in the M&S profession Such specializations may be located with reference to their place within the generic architecture. For example,  Hardware-centered professionals whose training would be centered in the technologies of the lower layers  Software-centered professionals whose training is concerned with developing the software that utilizes the hardware to support the applications  Applications-oriented professionals trained in particular application domains, knowledgeable in marshaling the M&S assets for application to problems in those domains  Facilitation professionals, a new breed, able to facilitate collaborations of other professionals using groupware technologies  M&S Scientists, responsible for researching the architecture itself, continually assessing its capabilities relative to the needs of the other professionals.

Summary/Implications A Broad Perspective of M&S into the Future is needed to properly plan for the education, training and certification of M&S Professionals There is not one M&S professional category but the ones that have/will emerge can be viewed within an orderly framework Implications for Certification are that we should plan now for the future expansion and population of the field by various specialists
