DSS construction based on the ontology of dairy production

The purpose of the work is to build and implement a decision support system (DSS) in dairy production based on formalized mathematical models and an ontological approach. The decomposition of the process of dairy production is carried out; the main factors influencing it and the relationship between them are highlighted. The ontology of the subject area has been formed, which is presented as a conceptual scheme and a class hierarchy. To describe the sequence of the influence of factors and identify control actions, the Ishikawa scheme for the production of dairy products has been developed. A formalized description of the efficiency of the dairy production process is proposed. A DSS has been developed for the production of dairy products, taking into account the factors associated with the variety and type of forage plants, methods of sowing seeds, pre-sowing preparation, class and type of soil, agro-climatic indicators, fertilization, class of animals and feed additives.
