The fault tree is a technique of high importance for reliability analysis in a industrial process. This paper describes an application that was developed for the automatic fault tree synthesis. In order to do so, the knowledge about industrial processes was structured through the development of a domain ontology. With this ontology is possible to represent the relationship between each component of...
In this paper an ontology driven approach to the design of control systems, in particular, control applications of IEC 61499 standard is proposed. The source ontology is an ontological description of control object (plant) while the target ontology is an ontological description of a control system implemented using an appropriate programming language. For the ontologies transformation an extension...
Condition-based maintenance (CBM) has been implemented in industry to arrange the maintenance work as efficiently as possible. Case-based reasoning (CBR) can be used to automate part of the CBM decision process. However, in complex situations the final decisions have to be made by domain maintenance experts based on information gathered from several sources. This paper presents an approach for utilizing...
Large systems engineering projects involve the cooperation of various stakeholders from different engineering disciplines. Individual stakeholders apply various tools and related data storage approaches that (a) might hinder seamless interoperability and (b) include limited capability to support data versioning. Project-level concepts enable the mapping of engineering data coming from different disciplines...
Execution of business processes is an important factor that distinguishes residential and office buildings based on their energy usage. Unlike residential buildings, in offices workflows determine how and when energy-consuming devices have to be utilized. Thus, energy efficient building automation systems for office buildings should take into account the dynamic and unpredictable nature of business...
As of today, building automation systems are present in almost any commercial building. They perform climate control, lightning control, access control, surveillance, and quite a few other tasks. As a result of their evolutionary development, building automation systems are divided into separate silos of disciplines that are not well integrated with each other. As of today, a variety of communication...
Current solutions to the interoperability problem in Home Automation systems are based on a priori agreements where protocols are standardized and later integrated through specific gateways. In this regards, spontaneous interoperability, or the ability to integrate new devices into the system with minimum planning in advance, is still considered a major challenge that requires new models of connectivity...
