The author attempts to to justify the necessary process parameters controlled aeration of grain for the purpose of drying. Applied a systematic approach. The drying process is presented in the form of interaction of the "drying agent" and "grain" layer. By using elements of information theory evaluated informative value of each of the elements in the system and the system as a whole on the basis of data on the state of the grain layer. Position aeration considered as objects with distributed parameters. It has been established that adequate process control aeration sufficient to control the parameters of drying agent inlet cereal layer.

The article considers one of the solutions to the problem of multi-criteria selection. Weights of the importance of the individual criteria are considered as uncontrolled factors and are calculated on the principle of guaranteed result at each point of the selection area. The method also allows taking into account the additional qualitative information about the DM preferences on the set of individual optimality criteria. Qualitative information about the preferences may be incomplete and may not provide a precise numerical estimates. The article provides analytical expressions for the automatic calculation of importance weights of taking into account individual preferences using the generalized logical criterion. The article considers the problem of approximating the area of efficiency in multiobjective optimization problems using the generalized logical criterion of optimality and makes the analysis of Pareto-efficiency area.

The paper discusses the issue of necessity of creation of residential area for teachers in the territory of newly projected campuses. It allows the University to invite highly qualified teachers, including from abroad. Providing the teachers and employees of the University with flats is the practice adopted before the revolution of 1917. The paper offers the norms for designing the flats of teachers of various categories (post-graduate students, professors). The evaluation of expenditures for construction of residential premises for the teachers and employees of the University, as well as dormitories for students has been conducted. The comparison of the cost of construction with the expenditures for a full cycle of preparation of a Specialist (Bachelor) in the University has been given. The author also comes to the conclusion that the presence of a parking zone in the campus is superfluous for the territories located to the north of the middle zone of Russia. The conformance of the campus to modern environmental requirements, in the author’s opinion, may be provided not only by the creation of parks, but by using building and premises arrangement technologies that save energy.

The paper considers the algorithms of position-trajectory control of mobile objects, are automatically distributed control forces and moments on the actuator. The basic control law is based on the equations of kinematics and dynamics and method of position-trajectory control of mobile objects. We consider the distribution of control forces and moments on the basis of pseudo-inverse matrix, which provides minimum MSE. This approach does not provide for preliminary separation of control channels, as is customary in classical systems of mobile objects. The proposed method is applied to the control system of aeronautical complex. The cases of excessive and insufficient number of control channels. The results of the simulation.
