analytical and simulation performance models
Can anyone please explain difference between analytical and simulation performance models?
Re: analytical and simulation performance models
An analytical model in the context of performance analysis usually refers to the modeling of an existing system as a queuing system. Queuing theory offers many such models including the M/m/1, M/m/n. Once the service times and interarrival times to the system are modeled as mathematical distributions, it becomes possible to predict average response times using these models.
Simulation generally refers to a prototyped implementation/stub of a system that is programmed to react in approximately the same way. It is a technique used at the drawing board stage where potential performance issues are being considered.
