Inventory levels are critical to the operations, management, and capacity decisions of inventory systems but can be difficult to model in heterogeneous, nonstationary throughput systems. Expand
A Queuing-Base Statistical Approximation of Hospital Emergency Department Boarding
A hospital Emergency Department’s (ED’s) wait times can be driven by high occupancy in its downstream InPatient hospital (IP). ED patients not admitted to the IP due to high IP occupancy or transfer… Expand
Resources and Capabilities of the Department of Veterans Affairs to Provide Timely and Accessible Care to Veterans.
The Veterans Access, Choice, and Accountability Act of 2014 addressed the need for access to timely, high-quality health care for veterans. Section 201 of the legislation called for an independent… Expand
Developing nonlinear queuing regressions to increase emergency department patient safety: Approximating reneging with balking
We hypothesize that the LWOT reneging percentage is captured by the balking probability (p"K) relationship of an M/M/1/K queue. We derive a binomial response nonlinear weighted regression model that best fits p"K for predicting LWOT to long-term ED performance by means of Gauss-Newton linearization. Expand
Introduction to time series analysis and forecasting : solutions manual to accompany
- D. Montgomery, C. L. Jennings, M. Kulahci, James R. Broyles, R. Johnson, Christopher J. Rigdon
- Computer Science
Introduction to Time Series Analysis and Forecasting presents the time series analysis branch of applied statistics as the underlying methodology for developing practical forecasts, and it also bridges the gap between theory and practice. Expand
Cataract Blindness and Simulation-Based Training for Cataract Surgeons: An Assessment of the HelpMeSee Approach.
Cataracts account for about half of all cases of blindness worldwide, with the vast majority in developing countries, where blindness and visual impairment can reduce life expectancy and economic… Expand
