Automated office systems are emerging as an interdisciplinary research area with a strong computer science component. In this paper we define office information systems as entities which perform document storage, retrieval, manipulation and control within a distributed environment. Some state of the art implementations are described. We relate the research to different areas of computer science...

Ethernet networks for automation systems promise standardized interworking between completely different devices from field level up to office level without connection and conversion difficulties. As Ethernet was not originally developed considering automation system requirements, its qualification, especially regarding topology and determinism demands, has to be examined. In this paper theoreti...

Abstract: Ahierarchicalmodel predictive controller (HMPC) is proposed for flexible and sustainable building automation. The implications of a building automation system for sustainability are defined, and model predictive control is introduced as an ideal tool to cover all requirements. The HMPC is presented as a development suitable for the optimization of modern buildings, as well as retrofit...

Ethernet has become increasingly popular in automation, due to its easy integration with other networks but also for its low costs and commercial availability. Characteristics like real-time capabilities required in automation have also been added and now form Industrial Ethernet allowing its deployment in application areas formerly reserved for dedicated fieldbus systems. Due to the vertical i...
