Service quality is often conceptualized as the comparison between service expectations and the actual performance perceptions. It enhances customer satisfaction, decreases customer defection, and promotes customer loyalty. Substantial literature has examined the concept of service quality, its dimensions, and measurement methods. We introduce the perceived service quality index (PSQI) as a sing...

--Traditional simulation methodology supports only changes in models’ state variables. Dynamic structure modeling allows to model both changes in state variables and changes in structure and has been applied to different applications. This paper focuses on the performance issue of dynamic structure implemented in the DEVS modeling and simulation environment. Six performance measurement metrics ...

Armed forces around the world are considering radical transformations to their structures and strategies because of the information revolution and the changing global environment. Senior leadership continually face decisions on how best to structure, modernize, organize, and employ forces in an increasingly uncertain future. For many of these problems analytical methods are not applicable, and ...

End-to-end available bandwidth estimation between Internet hosts is important to understand network congestion and enhance the performance of Quality-of-Service (QoS) demanding applications. In this paper, we investigate model-based available bandwidth measurement via the use of an active probing stream. A general end-to-end measurement framework, which unifies the current research approaches a...

Shared understanding is commonly seen as essential to the success of coalition operations, and current research efforts are attempting to develop techniques and technologies to improve shared understanding in military coalition contexts. In spite of this, our understanding of what the term ‘shared understanding’ actually means is surprisingly poor. In part, this problem is attributable to the d...

In this contribution we provide a simple and useful state estimation approach for a general class of non linear models that describe dynamic power systems. At first we show, through a small power network, that this class of systems is modeled by non linear differential-algebraic equations that we may always transform to a system of ordinary differential equations. After, we investigate a state ...
