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...

Produktionsplanung und -steuerung bei Einzel- und Kleinserienfertigung
Drexl, Andreas; Kolisch, Rainer - 1991
Produktionsplanungs- und -steuerungssysteme (PPS-Systeme) haben in den letzten Jahren in der wissenschaftlichen Literatur und der betrieblichen Praxis starke Beachtung gefunden. Während diese Systeme die Problematik der (Groß-) Serienfertigung (einigermaßen) bewältigen, sind sie für die...

The octograph and the delight of understanding organizational artistry: How to enjoy social interaction and stimulate job performance?
Al-Araki, Abdel Magid - In: Open Economics 2 (2019) 1, pp. 92-108
This paper proposes the Octograph, a cube-like model of leadership and organizational performance. Eight concepts, placed on eight corners of the cube, create eight triangular models and four processes of Decision-making, Communication, Production and Innovation. The eight concepts are nested...

Incentives for quality through endogenous routing / Lauren Xiaoyuan Lu; Jan A. Van
Xiaoyuan Lu, Lauren; van Mieghem, Jan A.; Savaskan, … - 2006
We study how rework routing together with wage and piece rate compensation can strengthen incentives for quality. Traditionally, rework is assigned back to the agent who generates the defect (in a self routing scheme) or to another agent dedicated to rework (in a dedicated routing scheme). In...
