Information System Supporting Decision-making Processes for Forming of Securities Portfolio

Due to large-scale changes in the economy in the world and in Ukraine in particular, there has recently been a significant increase in interest in the problems of investment theory. An example is the intensification in recent years of the purchase of shares of large international companies and cryptocurrencies and, according to the rapid growth of their values. It is known that as a special case, the theory of investment considers the task of optimizing investment portfolios.

APPLICATION OF FORMALIZED MODELS OF EVENTS FOR EVALUATION OF DANGER AND ACCIDENT ASSESSMENT OF THE COMPRESSOR STATION OF THE MAIN PIPELINE

An effective approach to solving the problem of reducing man-made hazards is the use of specialized systems for forecasting and minimizing risks. The theoretical basis for hazard assessment is probabilistic safety analysis (IAB). The most common method of assessing the danger and accident is the development of formalized models of events is the use of logical-probabilistic models "failure tree" (FTA) and "event tree" (ETA). These methods are widely used in the world to analyze the risk of accidents at facilities with increased levels of danger.

RISKS OF CAR PARTS PRODUCTION AND SMART METROLOGY

The study of the metrological risks of the car cables’ production is provided in the current issue. It is proposed to develop several different sampling methods to form lots for the study. Their capabilities are evaluated according to selected criteria based on the available technology. The advantages of the dynamic method according to the possibilities of operative metrological workshops are shown. Certain advantageous factors of the method (e.g. percentage of cables to be measured; the lot’s waiting time, etc.) have been identified.

Peculiarities of Choosing a Strategy for Development of Domestic Enterprises on the Basis of Analysis of Strategic Alternatives

The semantic load of the concept of “strategy” is analyzed, it is determined that the meaning of this term has changed over the last hundred years depending on the object and subject of research; The main three key concepts of strategy definition are considered, namely classical, conceptual and complex, which were singled out by Western scholars and which were partially supported by Ukrainian, as well as philosophical and organizational-managerial concept, which are singled out by purely domestic scientists.

Modeling in the Field of Freight Transportation: Ambivalence of Management Decisions in the Conditions of Quarantine Restrictions and Economic Competition

The study focuses on the ambiguity of management decisions in conditions of economic competition and quarantine restrictions. It is concluded that in the field of freight transportation there are antagonistic interests of the environment in the process of making management decisions by managers of JSC “Ukrzaliznytsia”. The classification of information situations related to the uncertainty of the environment is used, according to which the fifth information situation most closely corresponds to the current situation in the market of transport services.

Family in the system of risks of legal socialization

The tasks of the theory of legal socialization include the study of the holistic process of personality formation. The solution of this problem is complicated by the need to understand the problems and risks of legal socialization and the need to further development of sound recommendations for their prevention and overcoming. The concept of risk is multifaceted. The problem of risks is now widely discussed in scientific circles in assessing international, economic, social, legal, financial and other areas of government activity.

MANAGEMENT DECISIONS IN CLINICAL LABORATORY DIAGNOSTICS

Unfortunately, modern medicine,  unfortunately,  is  not without  errors. Therefore  there  exists  a  probability  of unpredictable complications, establishment of an incorrect diagnosis, and in consequence and improper treatment. When dealing with various medical problems (collecting information about the patient, diagnosis, choice of solution tactics), the doctor faces the problem of decision - making. At the same time, the requirements for the accuracy of the diagnosis and its reliability are constantly increasing.

INFLUENCE OF PETROL AND PETROLEUM COMPONENTS’ VAPOURS ON HUMAN ORGANISM

The work deals with the analysis of sources and ingression of petroleum vapours into environment, as well as with petrol losses and the dependence of the vapours concentration on the tank volume and the ambient temperature. The concentration of petroleum vapours at the petrol station and the individual risk of hazard level have been calculated. The chemical composition of petrol is shown, toxicity of its components and their influence on the human organism as a whole are analyzed.
