A Multi-Level Trend-Renewal Process for Modeling Systems With Recurrence Data

Zhibing Xu, Yili Hong, William Q. Meeker, Brock E. Osborn, Kati Illouz
2017 Technometrics  
To model the recurrent event data, the renewal process (RP), the nonhomogeneous Poisson process (NHPP), and the trend-renewal process (TRP) are often used.  ...  In this paper, we propose a general class of models to describe replacement events in a multi-level repairable system by extending the TRP model.  ...  repairable systems, extending the TRP model.  ...

Performance Analysis of Time-Dependent Queueing Systems: Survey and Classification

Justus Arne Schwarz, Gregor Selinka, Raik Stolletz
2015 Social Science Research Network  
Additionally, we identify links between the different approaches and provide a survey of applications that are categorized into service, road and air traffic, and IT systems.  ...  There are several approaches for the performance analysis of queueing systems with deterministic parameter changes over time.  ...  Brown and Ross [26] show that for the MðtÞ XðtÞ =GðtÞ=1 system, L S ðtÞ and the number of departures D S;c ðtÞ up to time t follow a compound Poisson process.  ...

Maintenance Models Applied to Wind Turbines. A Comprehensive Overview

Yuri Merizalde, Luis Hernández-Callejo, Oscar Duque-Perez, Víctor Alonso-Gómez
2019 Energies  
The decisions regarding O&M are based on different types of models, which cover a wide range of scenarios and variables and share the same goal, which is to minimize the Cost of Energy (COE) and maximize  ...  In this context, this review aims to identify and classify, from a comprehensive perspective, the different types of models used at the strategic, tactical, and operational decision levels of wind turbine  ...  Poisson (point processes, homogeneous Poisson process, nonhomogeneous Poisson process or power law process) [27] , with Weibull being the first used in reliability studies [69, 70] .  ...

A Queuing Approach to Parking: Modeling, Verification, and Prediction [article]

Hamidreza Tavafoghi, Kameshwar Poolla, Pravin Varaiya
2019 arXiv   pre-print
We present a queuing model of parking dynamics and a model-based prediction method to provide real-time probabilistic forecasts of future parking occupancy.  ...  For each location and each spot the data specifies the arrival and departure times of a truck, for 16 months of operation.  ...  Acknowledgments We would like to thank Pilot Travel Centers LLC and Sensys Networks, Inc. for sharing the data used in this study. We are grateful to Rahul Jain for his valuable comments.  ...

Cancer Evolution: Mathematical Models and Computational Inference

Niko Beerenwinkel, Roland F. Schwarz, Moritz Gerstung, Florian Markowetz
2014 Systematic Biology  
Evolutionary theory can be used to analyze the dynamics of tumor cell populations and to make inference about the evolutionary history of a tumor from molecular data.  ...  Cancer is a somatic evolutionary process characterized by the accumulation of mutations, which contribute to tumor growth, clinical progression, immune escape, and drug resistance development.  ...  The evolutionary dynamics of the average number of cells in a given stage can be modeled by a system of ordinary differential equations.  ...

A Comprehensive Survey on the Ambulance Routing and Location Problems [article]

Joseph Tassone, Salimur Choudhury
2020 arXiv   pre-print
The contributions of this work are a comprehensive survey of current methodologies, summarized models, and suggested future improvements.  ...  Although alike, a key distinction is emergency service systems (EMS) are considered critical and the optimization of these has become all the more important as a result.  ...  For their simulation they assumed a "non-homogeneous Poisson process" for arrivals and separated patients based on severity.  ...

Dynamic Assignment of Patients to Primary and Secondary Inpatient Units: Is Patience a Virtue?

Derya Kilinc, Soroush Saghafian, Stephen Traub
2016 Social Science Research Network  
Since the optimal policy for dynamically assigning patients to their primary and secondary inpatient units is complex and hard to implement in hospitals, we develop a simple policy which we term penalty-adjusted  ...  Developing a queueing-based Markov decision process, we first demonstrate that patience in transferring patients is a virtue, but only up to a point.  ...  Furthermore, we observe that the arrival process for each arrival source and for each IW can be modeled as a nonhomogeneous Poisson Process with a rate that is constant during one-hour time blocks.  ...
