Performance Prediction of Real-Time Command, Control, and Communications (C3) Systems
Abstract
Predicting the performance of a C3 system consisting of sub-systems requires the integration of such sub-system models with the communication system models. When the system is used for a time critical mission, the network delay may play a decisive role in battle management. The architecture of a C3 system is represented by two layers: the functional layer and the physical layer. The synthetic execution model contains both architecture layers as separate executable models. Then, the layered executable models are combined to develop a performance prediction model. The executable functional model uses a Petri net to describe the logical behavior and the executable physical model uses a queuing net to represent the demand and/or contention of resources. The message-passing pattern is generated from the executable functional model using a state space analysis technique. The executable physical model processes these messages preserving the message-passing pattern. Once the network delay is measured in the executable physical model it is inserted into the functional model.
