In the article, the analytical way of working out of mathematical model of process of heating of air for grain drying is shown. It is considered, that the temperature of a wall influences on dynamics of process of heating. Dynamic characteristics of the top internal device are considered. With use of package Mathcad schedules of transitive functions on operating and revolting influence are received. Results of modeling are presented

In the article, the structurally functional method of the search of the defects in the segment of the computer network is considered. The basis of this method makes: the structurally functional model of a network; the table of malfunctions; the vector of checks with the obvious address of the knot of the network

The article is devoted to an actual problem: increasing of reliability of expert estimates, due to attraction in group of the most competent experts for carrying out examination. The analysis of application of expert estimation in the field of operation of corporate and telecommunication networks is provided in the article. The technique of an assessment of competence of experts is offered. When assessing the competence of experts the following factors were considered: specialization of the expert, an experience and experience of its work in the field, scientific qualification, existence of scientific works on a perspective of carrying out examination. For identification of a priority of factors at determination of competence of experts it is offered to use a method of the analysis of hierarchies. The necessary number of experts for carrying out examination of objects is defined on the basis of application of the statistical analysis

In the article, the basic problems which experts in management at synthesis of digital systems of stabilization of parameters of technological processes face are shown. The exact samples of optimization of parameters of a regulator and reception of discrete models of digital devices are resulted; the comparative analysis of continuous and digital systems is given

The article presents the recommendations for a process control system of heated air for drying seeds. The problem of selecting a control device is solved. The calculations of transfer functions of the closed ACS are made. The optimal controller gains are found.
