Abstract: C3I system works as a “force amplifier” in modem warfare and is an extremelyly complicated information system. It is very important yet difficult to evaluate a C3I system. SEA is an influential method for C31 evaluation that compares the system capabilities and the mission locus in a common attribute space to evaluate the system measure of effectiveness. The key point of SEA method is to determine the mission lo?cus. However, the SEA method leads to the mission locus by the analytical function which is very difficult to reach at in practical situations. In order to solve the problem，a novel parallel numeric SEA algorithm was presented in this paper. Based on the universal principle oi independent monotony, the hyperbox is ap?plied for the numerical approximation of mission locus. By a simulated token-ring method, the processing is dealt with parallelly and the system effectiveness is evaluated with high efficiency. This algorithm mini?mizes the computation remarkably when searching for the mission locus. Moreover, it gets over the limita?tion of depending on the analytical function to get the mission locus, thus making it possible to get the mis?sion locus of complex systems. Finally, the algorithm was combined with the relevant means of simulation to evaluate the effectiveness of an abstract and typical distributed information processing system and the satis?factory result of the output was reached.
