On New Fuzzy Technology of Extreme Processes\u2019 Modeling (overview)<\/strong><\/p>\n\n\n\n

Abstract:<\/strong> The speech presents a new approach to the study of modeling of weakly structured processes by fuzzy dynamic systems (Extremal Fuzzy Dynamic System (EFDS)). Different from other approaches where the source of fuzzy uncertainty in dynamic systems is expert\u2019 s knowledge, this approach considers fuzzy time intervals in which expert reflects evaluations of systems states. This notably widens the area of studied problems. All these is connected to the incomplete, imprecise, anomalous and extremal processes in nature and society, where connections between the system\u2019s objects are weakly structured, which is caused by lack of complete objective information about the evolution of studied processes. This approach may successfully apply, For example, in<\/p>\n\n\n\n

1) complex engineering processes;<\/p>\n\n\n\n

2) decision making problems in economics and business for extreme environment;<\/p>\n\n\n\n

3) emergency management problems in after disaster region (evacuation processes, transportation of humanitarian aid goods, facility location in catastrophe areas, estimation of disease spreading in epidemical regions);<\/p>\n\n\n\n

4) research of complex systems of applied physics;<\/p>\n\n\n\n

5) conflictology, sociology, medical diagnosis;<\/p>\n\n\n\n

6) big data analytics, where big time series are transformed in EFDS; etc.<\/p>\n\n\n\n

One of our purposes is to create scenarios describing possible evolution of EFDS using methods of optimization developed by the framework of fuzzy sets theory. This includes construction of algorithms of fuzzy technology simulations of abnormal and extremal processes. Dual (extreme) approach to the research in weakly structured dynamic systems with respect to fuzzy-time is a novelty and does not have analogues today. The extremity of fuzzy processes allows fuzzy-dynamic systems and their prediction to be described by the \u201cextended current and compressed future fuzzy time intervals\u201d in phase-time intervals and thus obtain more reliable information on the expert, his knowledge, the study of EFDS, etc. We thus provide new types of structures for expert knowledge streams in synthesis and analysis problems. Taking into account the control element, for EFDS we construct new fuzzy-integral models. Reliable fuzzy-scenarios are also built for future time-intervals, and these scenarios provide new possibilities for challenging dynamic systems research. The software library representing a new instrument for projecting decision making intellectual systems and expert systems is constructed.<\/p>\n\n\n\n
