Method and means for the creation of multi-agent system of management and control over labour resources allocation.
Method of the labour resources distribution between the process tasks has been developed taking into account employees’ performance characterstics and their load level. A new approach with psy-factor consideration to the work efficiency estimation is suggested. Multi-agent system of management and control over labour resources allocation has been realized. - R. N. Kvetniy, O. Yu. Sofina.
Optimization of the method of inverse resonance filtration in problems of objects recognition on texture background.
The paper considers new approach to the solutions of the problems of objects recognition on texture background. Filtration of textures is suggested to perform using inverse resonant filter (IRF).Filter synthesis is based on approximation of background surface by Fourier series, which compise proper natural 2D oscillations of the background. - A. B. Rakytianska.
Solution of inverse problem on the basis of the basis of fuzzy logical equations and genetic algorithm.
