SURVIVABILITY OF REDUNDANT COMMUNICATIONS SYSTEMS,

A computer program is developed which is capable of investigating the survivability of a class of redundant communications systems. The systems simulated by the computer program are characterized by large numbers of communicating elements dispersed over an operations area. Each element has potentially perfect switching capabilities for relaying messages to neighboring elements. These systems are modeled by nodes, links, and zones. Nodes represent the communicating elements of the model zones and links are used to describe the command and control organization. A node is an element that can receive andor transmit information. A link represents communication between two nodes. Zones are arbitrary operations areas. By providing the required input data the program user is able to prescribe the number of each type node, command and control organization, communication capability, shape of the operational area, and system degradation. The computer performs a Monte Carlo analysis to obtain an estimate of the expected number of surviving missile launches controlled by at least one command post as a function of the model parameters.
