arXiv:2606.00795v1 Announce Type: new Abstract: Metamodels for discrete-event simulations approximate the behavior of simulation models without running expensive simulations. Prior work introduced modular dynamic Bayesian networks (MDBNs) -- a class of metamodels that can estimate a range of probabilistic and causal queries (PCQs) using a single, trained model -- but the method was limited to Markovian systems. In this paper, we initiate an extension of MDBNs to non-Markovian queues by approximating non-exponential distributions using phase-type distributions. This approach raises novel challe
This paper represents an ongoing academic effort to expand the capabilities of AI metamodels, building upon prior work in Markovian systems to address more complex non-Markovian scenarios.
Improved metamodeling for simulations, especially in non-Markovian systems, can significantly reduce the computational cost and time required for complex system design and analysis, leading to more efficient development cycles across various industries.
The ability of AI metamodels to approximate non-Markovian queue behavior improves their applicability to real-world systems with non-exponential distribution characteristics, expanding the fidelity and scope of simulation analysis.
