Modeling and simulation in support of Navy operational test and evaluation
Article Abstract:
OPTEVFOR is chartered by CNO as the Navy's independent test organization to conduct actual field test of new procurement systems. Prior to DOT&E's issuance of new policy guidance, any test issue which OPTEVFOR could not address during OT&E was left unresolved or limited comment was made based on extracts of precise technical information from pristine and less complex developmental tests. DOT&E has now recognized the contribution that logically applied modeling and simulation can make toward the evaluation of new warfare systems at each decision point in the procurement and implementation cycle. The use of M&S to supplement rather than replace operational testing is interpreted by DOT&E as being within the spirit and intent of the law. This brings about a significant change in the way OPTEVFOR does business. To incorporate a modeling and simulation capability at OPTEVFOR, a new organization has been established: the Modeling and Simulation Branch. The M&S Branch representative works with the OTD and advises him on the integration of M&S into OT&E, primarily to support those areas where actual testing is inadequate to provide answers to effectiveness or suitability issues, but also, to aid in OT&E test design and devise new system tactics. Major systems in development now using M&S to aid in early program assessments include SSN-21, using the NUSC SIM II model, and Standard Missle (SM-2) Block IV with its series of flyout and endgame portrayal models developed through the coordination of Raytheon.

On simulation modeling for FMS
Article Abstract:
A simulation model capable of representing a large variety of flexible manufacturing systems (FMS) has been developed. The software, written entirely in FORTRAN, can be used during the design and control stages of the FMS development. The several modules of the model are described. The model's validation is primarily examined by comparing its results with those obtained using a model written in a specialized simulation language, namely ECSL. Fifteen control strategies are defined and simulation results discussed. (Reprinted by permission of the publisher.)
