Method for analysis of C3 system of systems using transformation of federation into integrated simulation

Abstract

To analyze a complex system, many researchers in the modeling and simulation (M&S) domain recently have performed a simulation-based analysis based on the system of systems (SoS) concept, and a representative example is the C3 systems, consisting of communication (C) and command and control (C2) system. This approach, based on the SoS, has the advantage that it enables the detailed analysis, but requires a prolonged simulation execution time per one trial, which has difficulties in analyzing various parameters. To solve this problem, this dissertation proposes a method for analysis of C3 SoS using a transformation of a federation into an integrated simulation. This transformation technique reduces the execution time while maintaining accuracy by abstracting the system other than the one to be analyzed, consisting of two phases: 1) model hypothesis and 2) behavior function identification. In the former, we can construct an abstracted model for the simulation through the proposed extended formalism

in the latter, the characteristics of the model influenced by other systems can be expressed. From the case study on C and C2 analysis, the experimental results show that this method shortened the time considerably while maintaining the accuracy within an acceptable error range and we expect that this method will enable the exploratory analysis of the complex systems other than C3.
