The paper addresses performance modelling of safety critical Ethernet networks with special attention to in-car networks. A specific Ethernet/IP based in-car network is considered as use-case. The modelling is based on the analytical method Real-Time Calculus (RTC), providing hard bounds on delay and buffer utilization. We show how RTC can be applied on the use-case network. Furthermore, we dev...

A fundamental aspect of the design of an embedded system is the prediction of its performance in terms of timing, memory, or energy early in the design process. The objective of this task, typically referred to as systemlevel performance evaluation, is twofold. On one hand, it is instrumental for pre-validating a system design before any resources are invested for the actual implementation and,...

In this paper, we discuss the results of recently published analytical concepts for performance evaluation of packetswitched mobile radio networks. For comparison we regard the results of a simulation system (GPRSim), which emulates the GSM General Packet Radio Service (GPRS) in great detail. Our scope is to identify the possible reasons for deviations between analytical and simulation results ...

in this paper, an analytical study of the forced vibrations of hexapod table is studied. considering external force as a time sinusoid force, forced vibrations of the platform are investigated. resonance frequencies and vibrations of the moving platform are also calculated in different directions. the results of the analytical approach are verified using fem simulation. modelling the harmonic m...

This paper stands for an analytical approach modelling and exploring an evolutionary-space oriented business-domains. The space that we consider is intended to be complex emerging a set of heterogeneous evolutionary business-agents (e.g. Factories, Restaurants, etc.); it accordingly stimulates an analytical multi-layered structure headed for a hyper-space navigational framework. Agents have mul...

This paper presents a hybrid neuro-fuzzy methodology to identify appropriate global logistics (GL) operational modes used for global supply chain management. The proposed methodological framework includes three main developmental phases: (1) establishment of a GL strategic hierarchy, (2) formulation of GL-mode identification rules, and (3) development of a GL-mode choice model. By integrating a...
