This research develops and demonstrates a Hierarchical Production Planning System Simulator (HPPSS) for the analysis of feedback-and-control mechanisms between linear programming models at two levels within a Hierarchical Production Planning (HPP) system. This work focuses on planning levels dealing with tactical decisions. Three areas distinguish it from prior research. First, the HPPSS allows...

The simulation and visualization of biological systems is expected to enhance our understanding of biological processes towards the development of effective therapeutic treatments. Biological systems are inherently stochastic at the molecular level, exhibit modified behavior under crowded conditions and may be affected by spatial locality. Common simulation approaches fail to account for these ...

A simulator, which has process, controllers, and man-machine interface (MMI), can be configured as a hardware-in-the-loop system or a software-in-the-loop system. In this paper, these general simulator configurations are reviewed and applied to the liquefied natural gas carrier (LNGC). The characteristics of the LNGC process, control, and its simulator configurations are presented. The simulato...

Digital cameras are rapidly replacing traditional analog and film cameras. Despite their remarkable success in the market, most digital cameras today still lag film cameras in image quality and major efforts are being made to improve their performance. Since digital cameras are complex systems combining optics, device physics, circuits, image processing, and imaging science, it is difficult to ...

Backend dielectric breakdown is one of the major sources of wearout for microprocessors. We present test data and a methodology to accurately estimate the lifetime for a microprocessor system due to backend dielectric breakdown. Our methodology incorporates activity in the nets surrounding each dielectric segment in the layout, temperature, and all layout spacings among parallel tracks. We anal...

The computing industry is currently undergoing a quiet revolution. Along with the recent advances in LSI design and production, a new trend in computation is forming. Many corporations are realizing that an important part of the future of computers lies in distributed data processing. The emphasis here is not on distributed data, for this field has been extensively (though certainly not complet...

This paper describes a Web-based simulator of the Federal Energy Regulatory Commission (FERC) mandated Open Access Same-Time Information System (OASIS) network. The purpose of the simulator is to provide a tool for study of the various aspects of an OASIS network and to gain a strong intuitive feel for its operations. For a specified simulation period, the OASISNET simulator reproduces an OASIS...
