Large scale distributed systems and processes are conceived, built and maintained over several decades. Due to the complexities of dealing with large teams and diverse toolsets, very little performance modeling and analysis are typically performed, instead deferring such issues to the integration time and “observation-under-operation”. However, performance errors found during integration time are typically more expensive to correct, especially if they require architectural or interface changes impacting more than one subsystem, mandating multiple regression tests and justifications.

nVision mitigates and shifts these late stage project risks to earlier in the cycle, for effective risk management. Using well established mathematical analysis, simulation techniques and our own practical expertise, with the help of Lockheed Martin Advanced Technology Labs, we have developed an approach to modeling, analysis and simulation of architectures, and applied it to a sample project and process environment.
