Coordinated Spiral: Concurrent Modeling and Simulation Development with C4ISR Systems

摘要

Currently Modeling and Simulation (M&S) requirements in support of Command, Control, Communications, Computer, Intelligence, Surveillance and Reconnaissance (C4ISR) systems tend to be developed following the effected C4ISR system fielding. The resultant delayed fielding of the supporting M&S not only causes several problems from the viewpoint of the user (i.e., lack of training) but also is a potential advantage lost to both the C4ISR and M&S system developers. The popularity of the spiral development process with its shortened requirement to fielding timelines compounds this problem. M&S development conducted for a recent Joint Expeditionary Force Experiment (JEFX) produced an interface between the Air Warfare Simulation (AWSIM) and the Theater Battle Management Core System (TBMCS) which modified the traditional spiral development process as it occurs between C4ISR systems and supporting M&S. This modified process produced a workable interface faster, which not only provided users training prior to C4ISR system but also aided in the requirements/acquisition and test and evaluation processes. This paper discusses the modified spiral development process, its effects on the JEFX process and presents some lessons learned and suggestions for future modifications.
