چکیده

In this paper, we design a real time estimation system in complex system simulation research. The popular simulation technology High Level Architecture (HLA) is introduced. The logical structure of the system is constructed with three levels of data resource, component and application. The main functions of the system are given, including sample collection, real time estimation, result display, replay control and rollback control. Then the realization of the system is analyzed. The web-based display system, the replay and rollback control are discussed in detail. Finally the paper concludes with summaries and further developments. Key-Words: Real time estimation, Complex systems simulation, High Level Architecture, Replay,

Markovian Delay Prediction-Based Control of Networked Systems

A new Markov-based method for real time prediction of network transmission time delays is introduced. The method considers a Multi-Layer Perceptron (MLP) neural model for the transmission network, where the number of neurons in the input layer is minimized so that the required calculations are reduced and the method can be implemented in the real-time. For this purpose, the Markov process order...

Safety Verification of Real Time Systems Serving Periodic Devices

In real-time systems response to a request from a controlled object must be correct and timely. Any late response to a request from such a device might lead to a catastrophy. The possibility of a task overrun, i.e., missing the deadline for completing a requested task, must be checked and removed during the design of such systems. Safe design of real-time systems running periodic tasks under th...
