The structures representing the document flow processes in an organization are considered by synthesizing them from the simplest structures. Presented in the form of graphs the processes of movement of documents become formalized and unambiguously defined. Using classification of typical structures of information flows and available mathematical model of management system, it is possible to formalize processes of movement of documents and their interaction in the form of management model, and also to make technical specification for development of information system and finished formalized statement of the problem of structure-parametric synthesis
The paper provides mathematical modeling of processes occurring in the biotechnological system, using the example of the interaction of functional microorganisms with contaminating microflora, which is currently a promising scientific direction. The analysis showed that there are no existing studies on this issue, as well as systematic and integrated approaches to solving this problem that allow describing the processes under consideration. Therefore, it is necessary to analyze and build a system model that reflects the full range of interactions between useful and extraneous populations of microorganisms in the production of bakery products. System analysis and mathematical modeling of microbiological processes is a complex task. It is necessary to take into account a lot of factors, such as the simultaneous flow of several non-stationary processes; a lot of state parameters, including the analysis of relationships between them; changes in real-time technological parameters, in particular the main resource, taking into account various properties of microbial populations that affect the behavior of microbiological systems (mortality, birth rate, the existence of extraneous microflora, etc.), and other factors that directly affect the quality of the finished product. These factors characterize the complexity of forming a mathematical model that allows you to take into account all the main features of the production of bakery products. The existing mathematical apparatus and the system analysis of this kind of production carried out before considered the behavior of the population of beneficial microorganisms, but did not contain an analysis of the effect of contaminating microflora on it. The problem can be reduced to a system of differential equations describing the microbiological process as a whole. To describe the General model needed to describe an unknown function, including constraints on the parameters. In addition, you must set the initial and boundary conditions and determine the coefficients of the model. The paper offers a system model for analyzing the effect of plant additives on biotechnological properties and test quality indicators. The presented system model allows you to continue the study of the issues raised in the work, by further studying its components.
In the work the process of increase of efficiency in the functioning of hierarchical multi-level complicated organizational systems (HMCOS) is considered and the elements of operation in the considered systems. To solve this problem the tension level of HMCOS operation is involved. Basing on the formulated principles some normative parameters of HMCOS are defined. Validation of the operation process for HMCOS is performed by the normative parameters in the certain moments of time. Considering all of the stages in HMCOS functioning it was made a conclusion that while choosing the normative parameters for the estimates of functioning of the organizational systems in order to get uniform distribution of tension between the staff it seems reasonable to use entropy model.
The paper offers a comprehensive set of characteristics of integrated security systems for electronic document management, which allows conducting research on the degree of protection of such systems from external and internal threats from the point of view of system analysis and modeling their functioning in various conditions. Classification descriptions are given and data analysis is performed when modeling decision-making processes in integrated security systems on the example of responding to threats of information leakage through parametric channels. The optimal set of response measures is given for performing illegal actions by an attacker to intercept information via parametric channels when using the corresponding modes of operation of the TCP Protocol. The type of analytical models of performance characteristics of measures to respond to threats of information leakage through parametric channels is determined by the functional model of such measures. The resulting system-level characteristics of effective response to the threat of information leakage on parametric channels is based on the stochastic representation of the conditions for timely interventions.
