We survey recent developments concerning Sequest and Sequem, two simulation-based sequential procedures for estimating steady-state quantiles. These procedures deliver improved point and confidence-interval (CI) estimators of a selected steady-state quantile, where the CI approximately satisfies user-specified requirements on the CI's coverage probability and its absolute or relative precision. Sequest estimates ...

In a previous article, we studied a then-new class of standardized time series (STS) estimators for the asymptotic variance parameter of a stationary simulation output process. Those estimators invoke the well-known reflection principle of Brownian motion on the suitably standardized original output process to compute several "reflected" realizations of the ...

Innovation in Modeling and Simulation (M&S) refers to exploiting new ideas, exploiting new technology, and employing out-of-the-box thinking, which lead to the creation of new methodologies, techniques, concepts, frameworks, and software. This paper addresses the following questions: (a) what was the state of the art in M&S 50 years ago, ...

For 50 years, the Winter Simulation Conference (WSC) has brought together researchers and practitioners from the field of discrete-event simulation. This paper discusses the demographics of the authors of the many thousands of papers that have appeared in the WSC proceedings over that time span. From its origins as a ...

We present Sequem, a sequential procedure that delivers point and confidence-interval (CI) estimators for extreme steady-state quantiles of a simulation-generated process. Because it is specified completely, Sequem can be implemented directly and applied automatically. The method is an extension of the Sequest procedure developed by Alexopoulos et al. in 2014 ...

This tutorial discusses in depth the operational validation of simulation models after a brief overview of verification and validation of simulation models. The discussion of operational validation first covers the different approaches used for observable and non-observable systems. Next, various types of graphical displays of model output behavior are presented; ...

In this tutorial we discuss the use of a recently published statistical procedure for the validation of models that have their required model accuracy specified as a range, often called the acceptable range of accuracy. This new statistical procedure uses a hypothesis test of an interval, considers both Type I ...

We develop new point estimators for the variance parameter of a steady-state simulation process. The estimators are based on jackknifed versions of nonoverlapping batch means, overlapping batch means, and standardized time series variance estimators. The new estimators have reduced bias---and can be manipulated to reduce their variance and mean-squared error---compared ...

This article presents Sequem, a fully sequential procedure for computing point estimators and confidence intervals (CIs) for extreme steady-state quantiles of a simulation output process. The method is an enhancement of the Sequest procedure proposed by Alexopoulos et al. in 2014 for estimating nonextreme steady-state quantiles. Sequem exploits a combination ...

Modelling of detailed community interaction dynamics increases a public health organization's ability to contain a potential disease strain at an early stage. Due to its dense population and high levels of human movements and interactions, Hong Kong has suffered from various epidemic diseases. The use of non-medical interventions is often ...

We develop a mathematical model for planning and scheduling staff and demand, considering a time window for on-time demand fulfillment, as well as individual staff characteristics, preferences, and availability. We also discuss a version where the staff schedule is fixed. The model can be applied in many service settings, such ...

Sequest is a fully sequential procedure that delivers improved point and confidence-interval (CI) estimators for a designated steady-state quantile by exploiting a combination of ideas from batching and sectioning. Sequest incorporates effective methods to do the following: (a) eliminate bias in the sectioning-based point estimator that is caused by initialization ...

We propose a method for estimating the variance parameter of a discrete, stationary stochastic process that involves combining variance estimators at different run lengths using linear regression. We show that the estimator thus obtained is first-order unbiased and consistent under two distinct asymptotic regimes. In the first regime, the number ...

We propose SPSTS, an automated sequential procedure for computing point and confidence-interval (CI) estimators for the steady-state mean of a simulation output process. This procedure is based on variance estimators computed from standardized time series, and it is characterized by its simplicity relative to methods based on batch means and ...

The replicated batch means RBM method for steady-state simulation output analysis generalizes both the independent replications IR and batch means BM methods. We analyze the performance of RBM in situations where the underlying stochastic process possesses an additive initial transient. Our analysis differs from prior work in that the initial ...

We study asymptotically valid confidence intervals (CIs) for steady-state quantiles computed from nonoverlapping batches. Asymptotic validity of the CIs is established under conditions that are weaker and more easily verifiable than the usual mixing assumptions. The performance of the CIs is evaluated with a preliminary experimental study. These results form ...

Given an output process generated by a steady-state simulation, we give expressions for the mean-squared error (MSE) of several well-known estimators of the associated variance parameter. The variance estimators are based on the method of nonoverlapping batch means and on the method of standardized time series applied to overlapping batch ...

Output analysis methods that provide reliable point and confidence-interval estimators for system performance characteristics are critical elements of any modern simulation project. Remarkable advances in simulation output analysis have been achieved over the last thirty years, in part owing to the application of data-reuse techniques designed to improve estimator accuracy ...
