Abstract. The article attempts to use the mathematical apparatus of fuzzy logic for the evaluation of ecological and economic security of enterprises and assessment of the risks arising in the course of their economic activity. Zoning of threats to the ecological and economic safety and developed a method of assessing the effectiveness of the recommendations on the complex of necessary measures to prevent damage and to minimize losses. Keywords: ecological and economic security, fuzzy-multiple models, zoning threats, efficiency of the project.
The article deals the technique of application of neuro-fuzzy systems in problems of management of melioration of agricultural crops is considered. In particular, an adaptive network based on the fuzzy inference system is developed, a method for predicting data flows based on the neuro-fuzzy network is proposed, which is implemented in the MATLAB ANFIS module.
The article is attempted to use the mathematical apparatus of fuzzy logic for processing the initial data of the model of an intellectual system for assessing the environmental safety of irrigated agricultural land and assessing the risks arising in the course of economic activity in the conditions of differentiated placement of crops. There is a proposed scheme for formalizing indicators set at a qualitative level which is based on membership functions. To determine the form of the membership function, limit, critical and high values of the level of environmental safety are identified. When describing model elements, we use a set of fuzzy situations that characterize the space of possible states of these elements, as well as a set of relationships between them. The assignment of communications that fuzzily is characterized the degree of influence between the typical states of pairs of elements allows the formation of production models in the form of a variety of fuzzy rules. The quantitative result of the interaction of elements is determined on the basis of fuzzy inference. The representation of the proposed model allows us to obtain an integrated assessment of the state of environmental safety of land and comparative characteristics of the magnitude of security threats are based on their automated assessment. The implementation of the proposed model allows us to obtain an integrated assessment of the state of environmental safety of land and comparative characteristics of the magnitude of security threats based on their automated assessment. Zoning environmental security threats are based on model. The developed model allows us to formulate recommendations on the set of necessary measures to prevent damage and minimize losses, as well as to evaluate the effectiveness of their execution in each specific case.
The article discusses the possibilities of using the mathematical and instrumental enhancement of the multilayer Hamming network in the tasks of recognizing aerial photographs, in particular, the advantages of the neuromodel for implementing further research to solve the problems of increasing crop yield based on monitoring and segmentation of dry crop areas are highlighted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
