Ultra-large-scale systems

Companion to the 21st ACM SIGPLAN symposium on Object-oriented programming systems, languages, and applications, 2006
Scale changes everything. The trend in the design and development of software-intensive systems today is toward scale that increases in every measurable way. Lines of code, complexity, dependency, communication, bandwidth, memory, datasets, and many other measures for our systems continue to reach and exceed the limits of our ability to produce high ...

Large-Scale Modeling of Economic Systems

Complex Systems, 2013
Following the events of the credit crunch and the onset of a global recession, alternative ways of modeling modern economies and mechanisms for carrying out policy analysis are now an urgent priority. Traditional mathematical economics is widely viewed to have been compromised through gross simplifications with many assumptions that are now seen to be ...

Robust Optimization of Large-Scale Systems

Operations Research, 1995
Mathematical programming models with noisy, erroneous, or incomplete data are common in operations research applications. Difficulties with such data are typically dealt with reactively—through sensitivity analysis—or proactively—through stochastic programming formulations.

Large Scale Systems Control

Automation and Remote Control, 2019
In this paper we propose the quaternion-based control system for quadrotor. Adaptive scheme for thrust coefficients identification, based on speed-gradient method, is designed. Proofs of stability are provided, as well the results of numerical simulations.

ON THE STABILITY OF LARGE-SCALE POWER SYSTEMS

Journal of Cybernetics, 1977
Abstract This paper deals with the problem of transient stability of large-scale power systems by visting decomposition-aggregation techniques. In this approach based on a priori criteria, the system is decomposed to N-subsystems, the first (N— 1) subsystems described by linear model and the Nthdescribed by nonlinear model.

On the Determination of Large-Scale System Reliability

IEEE Transactions on Systems, Man, and Cybernetics, 1982
A new, exact formulation for the reliability index of mean frequency of system failure is developed which is particularly suitable for application to large-scale systems. This approach has advantages over other available methods in that it requires neither the analysis of each system state nor the identification of all system cut-sets.

Integration of Large Scale Systems

1994
To be able to handle the complexity of large scale systems development in a specific application domain, a product can be partitioned into systems which are independently developed in distributed projects. These systems are designed to work autonomously and to interoperate with the other systems in the domain as a “mega-system” to provide the necessary

A large-scale computer conferencing system

IBM Systems Journal, 1987
This paper discusses the relationships between computer-mediated communications and other forms of communication and describes a particular computer conferencing system in use within IBM. The system described is quite large, with over three thousand contributors and over twenty thousand readers.
