This article describes an operating environment for control systems. This environment contains the basic layers of a distributed operating system. The design of this operating environment is based on the requirements demanded by controllers which can be found in complex control systems. Due to the nature of real-time control systems, special attention has to be payed to an efficient implementat...

The document describes an innovative way to assess the effectiveness of internal IT controls where the control framework is first captured in the models and then the models are used to analyse the evidence gathered from the IT environment. The aim is to lift the risk and control management lifecycle from a series of people based processes to one where model based technology enhances, connects a...

Macro-level studies show that ICT has considerable economic effects through the expansion of ICT-related production of goods and services as well as via capital deepening. In the U.S., these effects are primarily driven by the use of ICT (Jorgenson, 2001; Oliner and Sichel, 2000), whereas in Finland they are primarily driven by the provision of ICT (Jalava, 2002; Jalava and Pohjola, 2002). Fric...

Shared services have been embraced by the private, and increasingly, the public sectors. Yet implementation has often proved to be difficult and the factors which are critical to success are not yet well understood. In this paper existing research in the area of critical success factors (CSFs) is examined and it is suggested that that research actually covers two distinct phenomena. One approac...

At flight speeds, the residence time for atmospheric air ingested into a scramjet inlet and exiting from the engine nozzle is on the order of a millisecond. Therefore, fuel injected into the air must efficiently mix within tens of microseconds and react to release its energy in the combustor. The overall combustion process should be mixing controlled to provide a stable operating environment; i...

In this paper, an Application Service Providing framework for the provision of real world scheduling applications as services, named SchedSP, is presented. The main assumption of this paper is that the main business tendency is for distant users to have relatively small computational capabilities with web access being the main remaining capability. Since scheduling applications are computationa...

Increased business dynamics mandates modern organizations to proactively prepare their response to operating environment changes. Typically, large size organizations consist of multiple interconnected departments. Individual department strategies need to be balanced so as overall organization performance is improved. With increased number of interdependent strategic parameters, complexity of th...

From a system thinking perspective, competition/cooperation boundaries govern the evolution of a firm’s adaptive strategic behaviour and drive it towards its desired objectives. By analyzing different scenarios using a system dynamic simulation approach and considering market competitive dynamics, this study explores the volume flexibility measure considering both the operating environment and ...
