Abstract:

The article develops a model for evaluating the effectiveness of a complex transport system based on the use of an information criterion to assess the effectiveness of actions to restructure it. The measure of the amount of information entered into a logistics transport complex system to eliminate the uncertainty of behavior, both of the system itself and of individual events, is taken as a parameter of the information criterion. At the same time, the developed model ensures the unity of efficiency meters in logistics transport systems, since it is based on methods for predicting the value of

The stages, methodology and complex design tools of electromechanical systems with inductions motors are substantiated. A quantitative assessment of the possibilities of increasing their economic efficiency using complex design according to the criterion of maximum income is provided. The expressions of complex criteria of efficiency, complex mathematical models and research methods are substantiated. The change in economic efficiency is determined when the value of design parameters deviates from the optimal value. Using the developed means of complex design can increase economic efficiency b

Abstract:

This article evaluates the performance of expected value and expected value-variance criteria in achieving risk efficiency in crop selection. Results indicate that the expected returns criterion achieves risk efficiency in many situations because of constraints. However, in the absence of many constraints the expected returns criterion performs poorly except when highly mean-dominant activities are present. The expected value-variance criterion achieves a high degree of risk efficiency for all situations examined. This result implies that criteria more complex than expected value-variance are

In the context of economic relations, the main criterion aimed at improving warehouse operations is the effectiveness of measures aimed at reducing damage to goods, speed of work and costs of warehouse operations. Criterion The choice in this case is Lean Six Sigma, as this method leads to cost savings, imp

Abstract:

A new method allowing the determination of normal modes corresponding to the complex ones identified on a structure is proposed. It is based on an appropriation technique applied to forced responses computed from the identified eigensolutions. The set of applied forces is optimized with respect to an appropriation quality criterion. The knowledge of both complex and normal modes allows the full generalized damping matrix to be determined. The complex modes can then be recalculated using the normal modes and the full generalized damping matrix which provides a test of validity by comparison wit

Abstract:

The means used at the present time for a complex evaluation of the efficiency of building enterprise activities are either oversimplified or too complicated. Therefore it is necessary to develop for practical needs convenient, simple and understandable means. The problem can be solved by methods based on a graphical-analytical interpretation. Among the comparatively simple means applied now for a complex evaluation are: by the sum of work places; evaluation based on a geometrical average; evaluation based on the sum of partial indices, etc. More complicated means include the multi-criteria com

Even though the rules for the free circulation of machinery within the European Union (EU) market have existed for more than 30 years, accidents related to their activities have constantly been reaching significant value. When designing a machine, the design must stem from a risk assessment, where all stages of its life cycle and the ways to use it must be taken into consideration. In industrial operations with old machinery, despite fulfilling its function reliably, the safety level is below the developing requirements for safe operations.

Abstract:

Does semantic communication require a semantic information theory parallel to Shannon’s information theory, or can Shannon’s work be generalized for semantic communication? This paper advocates for the latter and introduces a semantic generalization of Shannon’s information theory (G theory for short). The core idea is to replace the distortion constraint with the semantic constraint, achieved by utilizing a set of truth functions as a semantic channel. These truth functions enable the expressions of semantic distortion, semantic information measures, and semantic information loss. Notably, th
