Simulation optimization: a review of algorithms and applications
TL;DR: Simulation optimization (SO) refers to the optimization of an objective function subject to constraints, both of which can be evaluated through a stochastic simulation as discussed by the authors, where discrete or continuous decisions, expensive or cheap simulations, single or multiple outputs, homogeneous or heterogeneous noise, etc.
Journal ArticleDOI
Simulation optimization: a review of algorithms and applications
TL;DR: This document emphasizes the difficulties in simulation optimization as compared to algebraic model-based mathematical programming, makes reference to state-of-the-art algorithms in the field, examines and contrasts the different approaches used, reviews some of the diverse applications that have been tackled by these methods, and speculates on future directions in the fields.

Medium-term maintenance turnaround planning under uncertainty for integrated chemical sites
Satyajith Amaran,Satyajith Amaran,Tong Zhang,Nikolaos V. Sahinidis,Bikram Sharda,Scott J. Bury +5 more
TL;DR: This work addresses the scheduling of a set of plant turnarounds over a medium-term of several months using integer programming formulations and proposes combined robust optimization and stochastic programming formulations to address the problem.

Long-term turnaround planning for integrated chemical sites
Satyajith Amaran,Nikolaos V. Sahinidis,Bikram Sharda,Matt Morrison,Scott J. Bury,Scott Miller,John M. Wassick +6 more
TL;DR: This work investigates a discrete-time mixed-integer linear programming (MILP) model to perform turnaround optimization and proposes general formulations to tackle the problem of choice of sequence and timing of planned periodic turnarounds.
