We conducted a review of modern methodologies used for solving problems of this class. A structural-logical model was proposed to describe the system’s architecture. We developed a mathematical method for diagnosing failures based on analysing changes in the state of system information flows. This included failure diagnostic criteria for the method we developed. As a result, it allowed us to obtain the analytical functional dependencies for the detection and localization of failures in the system’s structural modules. Graphs are presented to illustrate the probability of the system’s non-failure versus time-of-failure detection and localization. We obtained logical conclusions about improving the quality of system functions using the methods we developed for automatic failure self-diagnostics.","PeriodicalId":372744,"journal":{"name":"2020 10th International Conference on Advanced Computer Information Technologies (ACIT)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124128109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The developed technique makes it possible to solve the classic problem of strategic management-the task of determining the optimal price and the optimum volume of sales, which allows to actualize the strategy of price policy of enterprise for profit maximizing.","PeriodicalId":372744,"journal":{"name":"2020 10th International Conference on Advanced Computer Information Technologies (ACIT)","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128019630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, transparency has to be established, thus users are aware about the processing of their personal data and can take control over the processing according to their preferences. This is done via privacy policies in practice and privacy languages in the literature that are negotiated via specialized user interfaces.

The optimum value of the coefficient of discount from rate of seaport at different ratios is identified from the analysis of such economic and mathematical model.Comparative calculations of profit with discount and without it conducted according to overload of oil at Odessa port production and transshipment complex show that for different possible values of the cost an optimal discount is 10 - 20 % of the basic rate, while freight traffic is increasing by 40 - 95 % and the total profit is increasing by 10 - 25 %, i.e. the proposed discounts mechanism is efficient and very effective.

One of the most important requirements is the application to non-invasive technologies that avoid the introduction of a measurement tool that violates the integrity of tissues, blood vessels or human organs. Rejection of invasive methods prevents possible trauma, infection, and pain for the patient. Also, non-invasive technologies provide continues real-time monitoring hemodynamic parameters. The article discusses the measurement procedures and methods for calculating the cardiac output parameter using existing methods. The existing methods are considered not only in terms of the possible accuracy of the values obtained, but also taking into account the advantages, disadvantages and limits of the measurement procedure in clinical practice. New, non-invasive cardiac output measurement techniques are already available in clinical practice, but the question of their accuracy is still not the only commonly accepted. In article also considered methods of estimation of reliability of received results of measurements by new developed, or existing methods and technics of measurement cardiac output parameter.
