Several studies have examined how the ISO 9001 Quality Management System standard predicts changes in organizational outcomes such as profits. This is the first large-scale study to explore how employee outcomes such as employment, earnings, and health and safety change when employers adopt ISO...

Due to lack of detention capacity (the U.S. government measures capacity by the number of detention beds), tens of thousands of apprehended illegal aliens are released into the U.S. interior each year, instead of being removed from the country. This vulnerability can be exploited by terrorist...

This paper argues that it is wrong to require that regressing the outputs of a trace-driven simulation on the observed … queueing systems. The conclusions are: (i) the naive intuitive test rejects a valid simulation model substantially more often … than the novel test does; (ii) the naive test shows "perverse" behavior within a certain domain: the worse the simulation …

We present a new method for constructing joint probability distributions of continuous random variables using isoprobability contours--sets of points with the same joint cumulative probability. This approach reduces the joint probability assessment into a one-dimensional cumulative probability...

Using common random numbers (CRN) in simulation experiment design is known to reduce the variance of estimators of …, specifically multiple comparisons with the best. These models explain the effect of CRN via a linear regression of the simulation … output on "control variates" that are functions of the simulation inputs. We establish theoretically, and illustrate …

Simple heuristic formulas are developed to estimate the simulation run lengths required to achieve desired statistical …-state characteristics such as expected equilibrium queue lengths.
