Simulation models contain many parameters that must be adjusted (calibrated) in advance to reduce the error between simulations and experimental results. Bayesian optimization is often applied to minimize error after only a few simulations. However, Bayesian optimization uses only error information, ignoring information on other simulation results. In this paper, we improve Bayesian optimization by utilizing both and show that other simulation results effectively reduce the dimensionality of the parameter space.

We develop a nested simulation optimization approach to solve this problem.

Liu T., Zhou E. Simulation optimization by reusing past replications: don’t be afraid of dependence // Proceedings of the 2020 Winter Simulation Conference K.-H. Bae, B. Feng, S. Kim, S. Lazarova-Molnar, Z. Zheng, T. Roeder, and R. Thiesing, eds. December 13-16, 2020. Orlando, Florida, USA. P. 2923-2934.
In this paper, we fill this gap by theoretically studying the stochastic gradient descent method with reusing past simulation replications. We show that reusing past replications does not change the convergence of the algorithm, which implies the bias of the gradient estimator is asymptotically negligible. Moreover, we show that reusing past replications reduces the variance of gradient estimators conditioned on the history, which implies that the algorithm can use larger step size sequences to achieve faster convergence.
