The Shape of the Loss Curve and the Impact of Long-Range Dependence on Network Performance

Mandjes, Michel; Boots, Nam Kyoo - 2001

Empirical studies showed that many types of network traffic exhibit long-range dependence (LRD),i.e., burstiness on a wide variety of time-scales. Given that traffic streams are indeed endowed withLRD properties, a next question is: what is their impact on network performance? To assess...

Fast Simulation of a Queue fed by a Superposition of Many (Heavy-Tailed) Sources

Boots, Nam Kyoo; Mandjes, Michel - 2001

We consider a queue fed by a large number, say n, of on-off sources with generally distributed on-and off-times. The queueing resources are scaled by n: the buffer is B=nb and link rate is C=nc.The model is versatile: it allows us to model both long range dependent traffic (by using heavy-tailed...

On the Optimal Policy for Deterministic and Exponential Polling Systems

Gaujal, Bruno; Hordijk, Arie; van der Laan, Dinard - 2005

In this paper, we consider deterministic (both fluid and discrete) polling systems with N queues with infinite buffers and we show how to compute the best polling sequence (minimizing the average total workload). With two queues, the best polling sequence is always periodic when the system is...

Profit-oriented shift scheduling of inbound contact centers with skills-based routing, impatient customers, and retrials

Helber, Stefan; Henken, Kirsten - 2007

This paper presents a profit-oriented shift scheduling approach for inbound contact centers. The focus is on systems in which multiple agent classes with different qualifications serve multiple customer classes with different needs. We assume that customers are impatient, abandon if they have to...

O papel da presidência na gestão da coordenação política governamental: Arranjos e dinâmicas de poder com a coalizão (1995-2010)

Lameirão, Camila Romero - 2015

The analysis of the relations between the Executive and Legislative Federal, in Brazil, relate the support of the partisan coalition to government initiatives in Congress with the parties'representation of the base in the ministries. These approaches suppose an understanding that the...

Welcome on board? Appointment dynamics of women as directors

Schoonjans, Eline; Hottenrott, Hanna; Buchwald, Achim - 2023

little about director appointment dynamics and the drivers and impediments of women appointments. This study builds on … negatively predicts the likelihood of additional women appointments. Further, we find evidence of a replacement effect, i.e. the … director appointments are gender specific and suggest that demand-side factors such as explicit and implicit norms drive women …

What do we know about no‐show behavior? A systematic, interdisciplinary literature review

Amberger, Caroline; Schreyer, Dominik - In: Journal of Economic Surveys 38 (2022) 1, pp. 57-96

No‐show behavior, a distinct form of absenteeism, is often problematic, particularly in the service industry. Given the growing relevance of the phenomenon in the industry, an increasing number of researchers from such different disciplines as educational economics, healthcare management...

Prevention and Mitigation of Epidemics: Biodiversity Conservation and Confinement Policies

Augeraud-Véron, Emmanuelle; Fabbri, Giorgio; Schubert, … - 2020

This paper presents a ﬁrst model integrating the relation between biodiversity loss and zoonose pandemic risks in a general equilibrium dynamic economic set-up. The occurrence of pandemics is modeled as Poissonian leaps in economic variables. The planner can intervene in the economic and...

Forecasting the distributions of hourly electricity spot prices

Pape, Christian; Vogler, Arne; Woll, Oliver; Weber, … - 2017

We present a stochastic modelling approach to describe the dynamics of hourly electricity prices. The suggested methodology is a stepwise combination of several mathematical operations to adequately characterize the distribution of electricity spot prices. The basic idea is to analyze day-ahead...

Difficulties in testing for capital overaccumulation

Kocherlakota, Narayana Rao - In: Quantitative Economics 15 (2024) 1, pp. 89-114

This paper reconsiders the question of testing for the presence of Pareto suboptimal capital overaccumulation in overlapping generations economies. The paper allows generation-specific technology shocks to evolve over time according to a stationary Markov chain, and assumes that an...
