  • Earlier 20 century, sociologist Pitirim Sorokin suggested a theory of socio-cultural dynamics as follows: development of social systems and their transition from one state into another occurred under the influence of values prevailing in society. Note that social and cultural values are generating one or another type of society (even civilization) while evolution of values leads society to a turning point of development where these values compulsorily disintegrate or go to a new level of functioning. Cited as example may be the collapse of the USSR and radical transformation of the Chinese economy.

  • The topicality and significance of the subject of dissertation. Experts by Synergy Research noted that the total market volume of neural networks by 2005 exceeded 10 billion, dollars, in 2014 the volume of cloud services amounted to more than 17 bln. dollars, an increase of 45% year of calculus1. Also, in the first quarter of 2015 the market volume of services designed to deploy cloud infrastructures, exceeded $ 5 billion., where the share of Amazon Web Services was 29%. Due to the dynamic increase in sales of cloud services in January-March 2015 Google's revenue increased by 74%, IBM - by 56%, while revenues Salesforce.com rose by 34%. Thus, in 2018 the market of public cloud services will take place an investment of $ 127.5 billion., And their size by this time will be increased by an average of 22.8% per year, which is six times greater than the projected growth of global IT-market2.
    Determination of hidden patterns, data classification, prediction of processes, as well as analysis of the studied process for large volumes of data and in terms of their uncertainty arc the main tasks of data mining. For complex, weakly formalized processes with fuzzy nestohastichnostyu and incompleteness in the source of information and situations of internal and external environment, not usually given the opportunity to build simple adequate mathematical models. Information about the parameters of such processes is usually expressed by experts in the form of words and sentences, ie, in linguistic form. In such cases, the simulation, decision-making and management tools appropriate to use the technology of soft computing (Soft Computing).

In this regard, the development of algorithms and software for generation of fuzzy models of classification tasks, assessment, forecasting and decision-making based on fuzzy inference rules, neural networks and evolutionary algorithms is an actual problem.
    Therefore, there is a need to develop methods and algorithms for solving data mining, ie the tasks of building fuzzy models classification, estimation and forecasting on the basis of fuzzy clustering, configuration parameters of the model using neural networks and evolutionary algorithms and fuzzy multi-criteria optimization that occurs when building the model.

  • The aim of the research work. The aim of this dissertation is to study the causes of caving during drilling and the development of measures for quality completion of wells in the complicated caving areas.
    Scientific novelty' of the research work is as follows:
    experimentally obtained dependence of the strength of the rock on the number and speed of round-trip operations;
    theoretically established the influence of "launch" of the pump pressure in the process of recovery of fluid circulation to the occurrence of fatigue stress on the rock;
    theoretically determined that the teeth of roller cone bit under certain specific heaviness causes the ultimate stress in the rock that goes well beyond the loop, which is the reason for the reduction of its strength and collapse;
    it was established that the roller bits cause deformation of rocks in the array, whereby the macro- and micro cracks arise where mud filtrate penetrates;
    the method is developed for caving forecasting technique based on zones of geophysical studies and research drilled solids (sludge) by comparing the actual density of rocks with a density of normally compacted rock (theoretical density of the breed).
