  • Network Planning in Road Construction

    The article discusses the method of network planning in road construction as a method of rational resource planning. The calculation of the main indicators of the network graph such as the early start of work, the late start of work, the calculation of the critical path as the probable time of the construction duration is given. Analysis of the network schedule allows you to identify the time reserve for reducing construction time by a reasonable redistribution of resources and equipment. The results of this study will allow at the planning stage to analyze the data and choose the most optimal option for construction from the position of the correct distribution of resources and equipment, as well as their savings. At the stage of construction, it will allow you to monitor and control the progress of construction work, thereby monitoring the flow of funds and achieve savings or the optimal amount of construction without risks. Also, the results of the study will allow, without critical changes, to reduce construction time without changing the sequence of construction technology and without increasing mechanisms and labor costs. Subsequently, the results of the study can serve as the basis for developing a mechanism for optimizing network schedules from the position of the redistribution of teams to carry out construction work, as well as a reasonable combination of works that use the same type of mechanisms.

  • The method of intellectualization of measurement procedures based on the use of adaptive models of dynamic processes of the combined maximum principle and the theory of regularization

    A method for the intellectualization of measurement procedures has been developed. It is based on the step-by-step optimization procedure, which provides a reduction of the stochastic estimation problem to a number of deterministic problems. The task of the first stage of optimization is the synthesis of an adaptive mathematical model of the measuring process based on the combined principle of maximum, which, unlike the known methods, will ensure the constructiveness of its use in the next stages of optimization. The task of the subsequent stages of optimization is to solve the estimation problem based on the regularization method A.N. Tikhonov. Equations of an iterative measurement procedure are obtained that differ from the state transition vector functions known in structure. It belongs to the category of intelligent measuring procedures, since it makes a targeted choice of the closest to the true value of the assessment of the measured parameter in the conditions of structural uncertainty of the model of the studied object and parametric uncertainty of the observation model.

  • Representation of a finite state machine in matrix-predicate form

    Finite state machines, being a mathematical abstraction, allow you to perceive information from the control object, process it and give signals to control the object. The disadvantages of the representation of complex production systems by a set of finite state machines include the complexity of carrying out logical and set-theoretic operations on them and the complexity of describing the parallelism that occurs in the operation of complex production systems. When specifying a finite state machine in the matrix–predicate form, due to the information redundancy, it is possible to avoid these difficulties. Matrix–predicate method allows you to uniquely set the finite state machine square matrix, which makes it possible to use the methods of the theory of matrices during the set–theoretic operations on them and it is possible to avoid isomorphism. The paper presents the developed methods of representation of a finite state machine using a multi-place predicate, which greatly simplifies its task.

  • The model of production management based on growth accelerators

    It is shown that the production conflict, both structurally and dynamically strictly determined within the paradigm of structural management of production. The system essence of the production conflict determines the need to involve methods and tools of system analysis, in particular, the method of cognitive analysis. The model of management of the production company is offered. The model is based on a distributed combination of positive feedback loops. The model allows to organize a continuous cycle of self-development. This is achieved by self-locking conflicts in the underlying loop factors. The principal difference of the model is the formation of two additional "positive" contours. These contours cover the tangent base contour. The formal increase in the number of growth accelerators increases the system's ability to overcome conflicts in the basic circuit. The dual-accelerator circuit is a guarantee of sustainable control . The control model demonstrates the growth of causal integration and the level of self-determination in comparison with the initial potential.
