If you've heard of simulation, what do you think? Are digital twin in Manufacturing or Supply Chain optimization included in the simulations? What else would it be?
Hi, first of all, let me refer on the following paper:
Hendrik van der Valk, Joachim Hunker, and Markus Rabe (Technische Universität Dortmund) and Boris Otto (Fraunhofer Institute for Software and Systems Engineering ISST, Technische Universität Dortmund): "Digital Twins in Simulative Applications: A Taxonomy", see: https://informs-sim.org/wsc20papers/278.pdf
This paper tries to comprehensively distinguish between simulation and digital twins on a scientific basis.
Simulation models are firstly aiming to mimic an non-existent system and environment to ensure that the proposed solution is feasible and meets the customer's requirements. It might be enhanced for emulation purposes to assist development. In a later stage by linking the simulation model online to the real system, it may be extended to a digital twin.
As I am coming from simulation engineering, for me the simulation model builds a profound basis for the pathway to decision automation. A autonomous running simulation model must contain sufficient reliable and resilient methods for automated decision making to perform a full model run.
Simulation does normally NOT include optimization. Optimization can either be done by result analysis and discovering improvements / spare unneeded resources.

How long does your organization retain original systems logs used to filter SOX-related actions into a system that requires review of the logs and retains the filtered logs for seven years? Does your organization consider those original system logs records subject to record retention requirements, or supporting information used to create the SOX records?
