System Dynamics vs. Discrete Event Simulation, Expert System
Posted: Wed Apr 11, 2001 12:05 am
Among classis SD applications is Supply Chain design, optimization etc.
Since "Industrial Dynamics" models of supplies chains were created to
demonstrate many different aspects ranging from ISCM to implementing
collaboration arrangements. In many aspects the advantages of SD approach
are clearly visible but has anyone tried to compare System Dynamics approach
to operations research, discrete-event simulation or expert systems?
When SD is better when it can work together with SD and when other options
are more suitable? Anyone has experience trying to use different approaches
to the same problem in logistics for example?
I am supposed to make a presentation about System Dynamics to a colleague
who is seriously in discrete event simulation and I would appreciate any
help in proving SD superiority BTW I have heard some companies are
trying to combine SD with discrete simulation? Can it be done seamlessly?
