Overview of RSAC System Software
This Note gives an overview of the RAND Strategy Assessment Center's (RSAC) software design and summarizes characteristics of the automated war gaming system. It reviews basic concepts and requirements and examines three different aspects of the RSAC software design: (1) System interface, including the complex communication among the RSAC system's various software modules; (2) the communication mechanism which promotes modularity, thus simplifying system integration, evolution, and maintenance; and (3) system control, which treats game phenomena with extensive use of co-routines managed by a coordinating program. The Note discusses interactive gaming with human teams, identifying several classes of interaction and describing techniques that promote it. Finally, it discusses the overall computing milieu characterized by operations on VAX 11-750 or VAX 11-780 computers, the C programming language, UNIX operating system, a computer code requiring about two megabytes of random access memory, and the potential for eventual operations on geographically separated microprocessors.
