An optical ring network employing optical packet switching is investigated. An analytical approach allowing the computation of end-to-end cell loss ratio (CLR) is proposed. The CLR dependence on topological parameters (number of stations), network parameters (number of wavelengths), and node structure (buffer capacity) is computed assuming a uniform traffic load. A discrete event simulation con...

Recent research advances in Discrete EVent system Specification (DEVS) as well as cellular space modeling emphasized the need for high performance modeling methodologies and environments. The growing demand for cellular space models has directed researchers to use different implementation formalisms. Many efforts were dedicated to develop cellular space models in DEVS in order to employ the adv...

The relentless quest for processing speed in the range of teraflops and beyond has accelerated the need for scalable, parallel, high-performance computing (HPC) systems. To meet this high bandwidth and low power requirements, optical interconnect-based system architectures are being implemented by the HPC industry. While computer-aided design tools have significantly assisted electronic system ...

Today, discrete-event simulation (DES) use in the manufacturing industry has become widespread, but far from all companies use this technology.Often simulation is used on a `one-shot' basis only, or as a standalone tool, reflecting a low level of integration. At the same time, a majority of companies do not use simulation at all. It is argued here that these companies lack methodologies for ado...

Construction projects are characterized by their dynamic nature and operational details. This paper presents a hybrid simulation methodology; designed to model construction projects. The methodology utilizes Discrete Event Simulation (DES) and System Dynamics (SD). DES has been widely used in modeling construction operations; however, it lacks the ability to model the global aspects of operatio...

Recently there has been an increased focus on the environmental aspects of the manufacturing industry across the world. Boeing and the National Institute of Standards and Technology (NIST) have studied the incorporation of Life Cycle Analysis (LCA) parameters into Discrete Event Simulation (DES) as a means to analyze sustainable performance in the manufacturing area. For machining, accurate ana...
