We present a methodology for characterization and optimization of SiGe HBTs from our 0.8 μm BiCMOS technology. It involves process calibration, device calibration employing two-dimensional device simulation, and automated Technology Computer Aided Design (TCAD) optimization. The simulation results show a very good agreement with experimental data. In particular, we perform an optimization of co...

This article focuses on the study of the modeling and simulation of an intelligent transportation system that uses discrete event system specification (DEVS)/high-level architecture (HLA), which is the methodology of hierarchical modular modeling and distributed simulation. The authors performed distributed homogeneous traffic simulation by extending an existing developed DEVS-based I 3 D 2 tra...

This paper deals with the use of computer simulation with the aim of achieving more efficient production in manufacturing and production systems. In our case, the possibilities of such use are demonstrated on particular examples from industrial practice. Some simulation studies are presented. The aim of these studies is to suggest and simulate experiments designed to increase productivity and t...

As construction projects become more complex in terms of financing, sourcing, multi-year build schedules and global integration, the use of more sophisticated analysis tools is critical to project success. The ability to accurately predict project schedule outcome and manage performance volatility is essential to controlling risk. One relatively new methodology in construction engineering is mo...

It is still an open question in parallel discrete event simulation what conditions influence the performance of parallel simulation paradigms. We have developed a simulation environment based on asynchronous cellular automata that facilitates basic research into the concepts of discrete event simulation and parallel discrete event simulation, such as the Time Warp paradigm. We address the trans...

Computer simulation of an information system prior to its implementation can predict time and workflow changes in a hospital department, while offering a common ground of communication across various levels in the organization. Often, the simulation can predict unexpected effects of changes to the work environment and allow experimentation with alternative scenarios at minimal cost to the depar...

With the adoption of integration and system perspectives in managing the manufacturing systems and the pressure imposed by the increased competition and rapidly changing business environment, the need has arisen for new approaches for simulating the manufacturing enterprise. We have proposed SDDES; a hybrid System Dynamics Discrete Event Simulation approach to simulating the integrated manufact...

Studying complex propagation phenomena is usually performed through cellular simulation models. Usually cellular models are specific cellular automata developed by non-computer specialists. We attempt to present here a mathematical specification of a new kind of CA. The latter allows to soundly specify cellular models using a discrete time base, avoiding basic CA limitations (infinite lattice, ...
