Criterion of Design of Experiments for Tasks of Decision Support Interval Model Creation

New criterion and method for design of experiments for two types of tasks of creation of decision support interval model are described. The first type is the tasks of control of permissible values of characteristics of technical, economic, ecological and other static systems. Second type of tasks - it is the tasks of choice of optimum decisions by the criterion of minimization or maximization of value of objective function.

Identification the interval difference operators based on artificial bee colony algorithm in task of modeling the air pollution from vehicular traffic

The method of structure identification of interval difference operators, based on principles of the bee colonies functioning is represented. An example of the implementation of method for modeling of atmosphere pollution by harmful vehicle emissions is considered.

Mathematical models of informative characteristic of tissues in surgical wound at monitoring the recurrent laryngeal nerve by electrophysiological method

In this paper the different approaches to creating the mathematical models for identification the recurrent laryngeal nerve by electrophysiological method are given.

Using a neural network with radial basis functions for task of recurrent laryngeal nerve monitoring based on electrophysiological approach

Electrophysiological approach of stimulation of surgical wound tissues for recurrent laryngeal nerve (RLN) localization is considered. It is proposed to use neural network (NN) that identifying the distance from stimulation point to RLN for this purpose. Method of NN learning based on interval data analysis is proposed.

Mathematical and software tools for modeling objects with distributed parameters

In this paper the software system for constructing the mathematical macromodels for objects with distributed parameters using different methods of structure and parameters identification is considered.

Formalization the task of increasing the websites attendance based on management the dynamics of their characteristics

It is shown in this paper that mathematical model of dynamics of Web site quality characteristics can be represented in kind of a system of linear differential equations with a set of influential factors. The main quality indicators of Web sites were defined and analyzed. At that integrated index of attendance is weighed value of Web site quality characteristics.

Macromodel of dynamics of the electric power generated by small hydroelectric power station based on interval data analysis

An approach to constructing the macromodel of dynamics of electric power generated by Small HydroElectric Power Station (SHEPS) based on interval data analysis is presented in the paper. A new method the estimation of macromodel parameters is proposed. Unlike the existing ones it provides possibility to get the multiple estimations of parameters and also it has low computational complexity.

Methods and tools for reducing the risk of damage the reverse laryngeal nerve during the surgical operation on a thyroid

The new method and tools for reverse laryngeal nerve identification from the muscle tissue in the operational wound during the operation on thyroid is proposed in this paper. New approach is based on creation the interval model of distance from probing point on a surgical wound to laryngeal nerve.

Design of Sequential Experiment for Creating of Interval Model for Ecological Monitoring Systems

The process of construction of interval model of the field of nitric oxide concentrations based on results of sequential experiment is presented in paper. This model is used in the task of the ecological monitoring for a decision-making about a presence or absence of exceeding of boundary permissible concentration.

Estimation of Efficiency of Adaptive Procedure of Creation of Interval Models for Decisions Support

In paper the efficiency of optimum adaptive procedure of decisions support is described, which based on interval model that created by the result of sequential experiment.
