Implementing system simulation of C/sup 3/ systems using autonomous objects

Abstract

The basis of all conflict recognition in simulation is a common frame of reference. Synchronous discrete-event simulation (DES) relies on the fixed points in time as the basic frame of reference. Asynchronous DES relies on fixed points in the model space as the basic frame of reference. It is pointed out that neither approach provides sufficient support for autonomous objects. The use of a spatial template as a frame of reference is proposed to address these insufficiencies. The concept of a spatial template is defined, and an implementation approach is offered. The use of this approach to analyze the integration of sensor data associated with command, control, and communication (C/sup 3/) systems is discussed. The spatial template basis of model coordination and the use of object-oriented software provide a mechanism for implementing autonomous objects in a DES modeling paradigm and computer software. The availability of such simulation tools has the potential to change the scope and level of use in systems analysis in general and in C/sup 3/ systems analysis in particular. >
