An Introduction to Multiobjective Simulation Optimization [PDF]

open access: yesACM Transactions on Modeling and Computer Simulation, 2019
The multiobjective simulation optimization (MOSO) problem is a nonlinear multiobjective optimization problem in which multiple simultaneous and conflicting objective functions can only be observed with stochastic error. We provide an introduction to MOSO at the advanced tutorial level, aimed at researchers and practitioners who wish to begin working in

Estimation of contamination release histories using meshless radial point collocation method and multiverse optimization

open access: yesJournal of Hydroinformatics, 2023
Contaminants in groundwater may enter through various sources which are required to be identified for informed decision-making regarding remediation. In early stages of contamination of an aquifer, the sources of contamination are generally unknown.

A tutorial on simulation optimization [PDF]

open access: yesProceedings of the 24th conference on Winter simulation - WSC '92, 1992
This tutorial discusses the issues and procedures for using simulation as a tool for optimization of stochastic complex systems that are modeled by computer simulation. It is intended to be a tutorial rather than an exhaustive literature search. Its emphasis is mostly on issues that are specific to simulation optimization instead of concentrating on ...
