Altering the environment to improve appointment system performance
(Informs, 2019-06)
Current research on clinic performance is focused primarily on appointment scheduling rather than shaping the clinical environments. The goal of this study is to investigate the impact of environmental factors on the total ...
The golden rule of forecasting: objections, refinements, and enhancements
(Elsevier, 2015-08)
In providing a “golden rule” for forecasting, Armstrong, Green, and Graefe (this issue) raise aspirations that reliable forecasting is possible. They advocate a conservative approach that mainly involves extrapolating from ...
Software diversity for improved network security: optimal distribution of software-based shared vulnerabilities
(Informs, 2017-12)
Firms, and other agencies, tend to adopt widely used software to gain economic benefits of scale, which can lead to a software monoculture. This can, in turn, involve the risk of correlated computer systems failure as all ...
An integrated analysis of capacity allocation and patient scheduling in presence of seasonal walk-ins
(Springer Nature, 2019-06)
This study analyzes two decision levels in appointment system design in the context of clinics that face seasonal demand for scheduled and walk-in patients. The macro-level problem addresses access rules dealing with ...
Communicating forecasts: the simplicity of simulated experience
(Elsevier, 2015-08)
It is unclear whether decision makers who receive forecasts expressed as probability distributions over outcomes understand the implications of this form of communication. We suggest a solution based on the fact that people ...
A universal appointment rule in the presence of no-shows and walk-ins
(Wiley, 2012-07)
This study introduces a universal “Dome” appointment rule that can be parameterized through a planning constant for different clinics characterized by the environmental factors—no-shows, walk-ins, number of appointments ...
Predicting the performance of queues–A data analytic approach
(Elsevier, 2016)
Existing models of multi-server queues with system transience and non-standard assumptions are either too complex or restricted in their assumptions to be used broadly in practice. This paper proposes using data analytics, ...
A universal appointment rule with patient classification for service times, no-shows and walk-ins
(Informs, 2014)
This study evaluates patient classification for scheduling and sequencing appointments for patients differentiated by their mean and standard deviation of service times, no-show, and walk-in probabilities. Alternative ...
Managing clinic variability with same-day scheduling, intervention for no-shows, and seasonal capacity adjustments
(Taylor & Francis, 2020-01-02)
This study investigates demand and capacity strategies for managing clinic variability. These include (i) same-day scheduling to control random walk-ins, (ii) no-show intervention, where the clinic calls advance-booked ...
