Journal ArticleDOI
Simulation optimization for an emergency department healthcare unit in Kuwait
TL;DR: Experimental results show that by using current hospital resources, the optimization simulation model generates optimal staffing allocation that would allow 28% increase in patient throughput and an average of 40% reduction in patients' waiting time.
Journal ArticleDOI
Optimizing the Supply Chain of a Petrochemical Company under Uncertain Operating and Economic Conditions
TL;DR: In this paper, an optimization model for the supply chain of a petrochemical company operating under uncertain operating and economic conditions is developed and tested, and uncertainties in key parameters are introduced.
Journal ArticleDOI
Simulation-based optimization using simulated annealing with ranking and selection
TL;DR: A new iterative method is presented that combines the simulated annealing method and the ranking and selection procedures for solving discrete stochastic optimization problems and is guaranteed to converge almost surely to a global optimal solution.
Journal ArticleDOI
Simulated annealing for discrete optimization with estimation
TL;DR: A modified SA algorithm is presented and it is shown that under suitable conditions on the random error, the modifiedSA algorithm converges in probability to a global optimizer.
Journal ArticleDOI
Simulated annealing for the unconstrained quadratic pseudo-Boolean function
TL;DR: Computational results and comparisons demonstrate the efficiency of the simulated annealing (SA) based heuristic in terms of solution quality and computational time for the unconstrained quadratic pseudo-Boolean function.
