2015 IEEE International Conference on Automation Science and Engineering (CASE), 2015
Simulation models of different fidelity levels are often available for the same complex system. High-fidelity models generate accurate measurements of the performance of a system design but can only be simulated for a very limited number of designs due to its prohibitively expensive computation cost. In contrast, low-fidelity models produce approximate

27th Annual Simulation Symposium, 2002
A novel method for the yield simulation of integrated circuits based on an approximation of circuit performance is proposed. By using this method, only one complete circuit simulation is needed for the estimation of yield. To estimate the gradient of yield, only one circuit simulation and a sensitivity analysis at the nominal point are required, so the

Rapid Screening Procedures for Zero-One Optimization via Simulation
INFORMS Journal on Computing, 2013Some existing simulation optimization algorithms (e.g., adaptive random search) become pure random search methods and thus are ineffective for the zero-one optimization via simulation problem. In this paper, we present highly efficient rapid screening procedures for solving the zero-one optimization via simulation problem.

A multiquadrics-based algorithm for the acceleration of simulated annealing optimization procedures
IEEE Transactions on Magnetics, 1996A procedure to significantly reduce the computational cost of the simulated annealing optimization algorithm coupled with analysis methods is proposed for EM devices. The chosen approach relies on the application of the simulated annealing method to an analytical approximation of the true objective function, expressed in the form of a multiquadric ...

An Efficient Initialization Procedure for Simulation and Optimization of Large Distillation Problems
Industrial & Engineering Chemistry Research, 1997An efficient initialization procedure for steady-state distillation simulation problems involving a large number of components is presented. The proposed initialization procedure employs lumping and delumping of the components present in the mixture. The problem of initialization is then reduced to a system of component mass balance equations for each ...

An Efficient Procedure for Expensive Reservoir-Simulation Optimization Under Uncertainty
SPE Economics & Management, 2013Summary Many oilfield optimization problems concern expensive numerical-reservoir-simulation-based objective functions. These are computationally demanding and can require a significant amount of time to evaluate. With the addition of uncertainty in the underlying models, the computational cost is exacerbated and the collective cost ...

Discrete-event simulation optimization using ranking, selection, and multiple comparison procedures
ACM Transactions on Modeling and Computer Simulation, 2003An important use for discrete-event simulation models lies in comparing and contrasting competing design alternatives without incurring any physical costs. This article presents a survey of the literature for two widely used classes of statistical methods for selecting the best design from among a finite set of k ...
