Intelligent Computing on the Basis of Cognitive and Event Modeling, and Its Application in Energy Security Research

Abstract

The paper considers the issues of implementation and application of intelligent computing on the basis of cognitive and event modeling in research on energy security. The authors suggest a two-level information technology for the research. The first level suggests a situation analysis using the intelligent computing techniques. The analysis results are then used to choose rational variants of energy development in Russia (or its regions). At the second level these variants are computed with the multi-agent software INTEC-M. Transition from the first to the second level is automated by the tools of deductive program synthesis, that are based on declarative descriptions, i.e. formulae of restricted predicate calculus, and representation of input data by XML files. Cognitive and event modeling is considered in more detail. The examples of cognitive and event models are presented. The structure of a knowledge space is developed to support the intelligent computations. The knowledge space includes ontological models, databases of cognitive and event models, and the database on the cases of energy emergency situations. The authors developed the CogMap and EventMap tools to support cognitive and event modeling on the basis of common graphical environment GirModeling, and the expert system “Emergency”. The tools and expert system that support the knowledge base on energy emergencies are integrated within the intelligent IT environment. The research presented in the paper was partially supported by the grant of Presidium of RAS No. 2.2-2012 and grants of Russian Foundation of Basic Research No. 10-07-00264, No. 11-07-00192, No. 11-07-00245, and No. 12-07-00359.

Assessment of the energy systems resilience using artificial intelligence methods

“…Semantic modeling methods were considered by the authors in a number of publications, including [1,3], the basic concepts of cognitive modeling are discussed in [5], so we will not dwell on them here. Let's take a closer look at the use of machine learning methods.…”

“…Each of the ES threats is realized due to a combination of a number of factors influencing the occurrence of ExS. A qualitative assessment of a number of factors influencing the occurrence of ExS was proposed as a preliminary assessment before carrying out calculations, and a formalization of the formulation of the cognitive modeling task for energy security research is presented in [5]. The indicative analysis is aimed at determining the level of energy security, and the following ratio must be met:…”

“…where IN is the indicator value that determines the normal level of energy security, IJ is the current indicator value, IC is the indicator value that determines the crisis level of security [5].…”

Public health component in building information modeling

“…According to general information modeling literature [4][5][6][7][8], the basis of the BIM concept are the processes and ways of working together with information about the construction object. BIM embraces all the life cycle stages of a structure: planning, preparation of technical specifications, design and analysis, issuance of working documentation, production, construction, operation and maintenance, and dismantling.…”
