Feasibility study of variance reduction in the logistics composite model
The Logistics Composite Model (LCOM) is a stochastic, discrete-event simulation that relies on probabilities and random number generators to model scenarios in a maintenance unit ...

Implications of heavy tails on simulation-based ordinal optimization
We consider the problem of selecting the best system using simulation-based ordinal optimization. This problem has been studied mostly in the context of light-tailed distributions...

Single-stage multiple-comparison procedure for quantiles and other parameters
We present a single-stage multiple-comparison procedure for comparing parameters of independent systems, where the parameters are not necessarily means or steady-state means. We a...

Confidence interval estimation using linear combinations of overlapping variance estimators
We develop new confidence-interval estimators for the mean and variance parameter of a steady-state simulation output process. These confidence intervals are based on optimal li...

A teragrid-enabled distributed discrete event agent-based epidemiological simulation
We discuss design issues related to the transformation of a mature Agent-Based Model (ABM) for computational epidemiology into a “grid-aware” version. EpiSims is a distributed...

Empirical investigations of conceptual modeling and the modeling process
Conceptual modeling, deciding what to include in the model, is a very important task in the modeling process. However, it has so far received relatively little attention in the li...

Stochastic trust region gradient-free method (strong): a new response-surface-based algorithm in simulation optimization
Response Surface Methodology (RSM) is a metamodelbased optimization method. Its strategy is to explore small subregions of the parameter space in succession instead of attempting ...

Sensitivity analysis on causal events of WIP bubbles by a log-driven simulator
Fluctuations of work-in-progress (WIP) levels cause variability of cycle time and often lead to productivity losses in semiconductor wafer fabrication plants. To identify sources ...

Simulation assisted match-up rescheduling of flexible production systems subject to execution exceptions
An immense amount of research work has been done in the areas of scheduling and re-scheduling of various types of manufacturing systems. In this paper we present a simulation assi...
