Authors: Kornecki, Andrew J.; Wierzchon, Slawomir T.; Zalewski, Janusz
Abstract: The objective of this paper is to present a new approach to reasoning under uncertainty, based on the use of
Bayesian belief networks (BBN’s) enhanced with rough sets. The role of rough sets is to provide additional reasoning to
assist a BBN in the inference process, in cases of missing data or difficulties with assessing the values of related
probabilities. The basic concepts of both theories, BBN’s and rough sets, are briefly introduced, with examples showing
how they have been traditionally used to reason under uncertainty. Two case studies from the authors’ own research
are discussed: one based on the evaluation of software tool quality for use in real-time safety-critical applications, and
another based on assisting the decision maker in taking the right course of action, in real time, in the naval military
exercise. The use of corresponding public domain software packages based on BBN’s and rough sets is outlined, and
their application for real-time reasoning in processes under uncertainty is presented.2013-01-01T00:00:00ZIntegration of BACNET OPC UA-Devices Using a JAVA OPC UA SDK Server with BACNET Open Source Library ImplementationAnantalapochai, NaksitSikora, AxelEberlein, DavidKunz, Dominique-Stephanhttp://dspace.wunu.edu.ua/handle/316497/309292018-07-23T08:34:54Z2013-01-01T00:00:00ZTitle: Integration of BACNET OPC UA-Devices Using a JAVA OPC UA SDK Server with BACNET Open Source Library Implementation

Abstract: The variety of technologies used in modern Building Automation Systems (BAS) calls for methods to support
interoperability of the devices from different technologies and vendors. OLE for Process Control Unified Architecture
(=OPC UA) provides the possibility to enable secure interoperability of devices with platform independence and
efficient information model features. However, OPC has not found broad space in the world of building automation, yet. In this paper, results and experiences from a project are presented, where BACnet devices are mapped to OPC UA
standard models. The values and controls are presented by the OPC UA server running on an embedded device. In this
paper, we map the BACnet information models into the corresponding OPC UA information models. The actual data
(in OPC UA form) of the BACnet devices can be accessed by connecting an OPC UA Clients to the OPC UA Server.
This objective was be pursued by using as many available open-source projects as possible.2013-01-01T00:00:00Z
