In this demonstration we present the MICIE platform for on-line risk assessment in scenarios with heterogeneous interdependent Critical Infrastructures (CIs) such as power distribution networks, power plants, refineries, water distribution networks, transportation systems and telecommunication networks. These CIs are highly exposed to a large number of threats, including natural hazards, compon...

Due to the rapid advancements of computing, telecommunication and control technologies, the use of Transportation Information System (TIS) has become very popular. Under such system, the public would be able to obtain traffic and transport information in real time through private or public service providers via various means such as variable message signs, Internet, and mobile phones, etc. The ...

Recursive queries are required for many tasks of database applications. Among them we can mention Bill-Of-Material (BOM), various kinds of networks (transportation, telecommunication, etc.), processing semistructured data (XML, RDF), and so on. The support for recursive queries in current query languages is limited. In particular, this concerns corresponding extensions of SQL in Oracle and DB2 ...

In the colourful travelling salesman problem (CTSP), given a graph G with a (not necessarily distinct) label (colour) assigned to each edge, a Hamiltonian tour with the minimum number of different labels is sought. The problem is a variant of the well-known Hamiltonian cycle problem and has potential applications in telecommunication networks, optical networks, and multimodal transportation net...

Telemedicine provides medical information and services using telecommunication technologies. It includes systems for remote clinical care and consultation through the use of electronic imaging equipment. In wireless telemedicine, broadband multimedia information that is a combination of video, audio and externally acquired images is transmitted. Emergency medicine helicopters take an important ...

The purpose of this paper is to formally describe new optimization models for telecommunication networks with distributed processing. Modern distributed networks put more focus on the processing of information and less on the actual transportation of data than we are traditionally used to in telecommunications. This paper introduces new approaches for modelling decision support at operational, ...

Today, Vehicular Ad Hoc Network (VANET) is an emerging technology. The routing problems in heterogeneous network become popular research area in the field of VANET for supporting different aspects of Intelligent Transportation System (ITS) applications. With the progress of wireless radio technology, telecommunication, various wireless specifications and protocols form the heterogeneous network...

In this paper, we survey applications and algorithms pertaining to an important class of price setting problems formulated as bilevel programs. Introduction. Bilevel Programming. The present paper focuses on a specific class of bilevel problems that arise naturally when tariffs, tolls or devious taxes are imposed on a set of commodities. Not only does this class encompass several important opti...

The reasons for flaws of technological development at present are pointed out. Examples from complex projects like in telecommunication, transportation, or Electronic Data Interchange for Administration, Commerce and Transport (EDIFACT) are giving insight. The change of actors of the past intensifies tremendously the difficulties given by globalization and complexity of new systems for developi...

Facility location is a complex real-world problem which needs a strategic management decision. This paper provides a general review on studies, efforts and developments in Facility Location Problems which are classical optimization problems having a wide-spread applications in various areas such as transportation, distribution, production, supply chain decisions and telecommunication. Our goal ...
