Expert system as a means for optimizing cattle diets

Existing expert systems for optimizing cattle diets were studied, the ISO 9126 quality model was chosen to formulate requirements and evaluate existing systems. A mathematical model for optimizing animal feed rations was developed based on the linear programming problem, which is to minimize the objective function for the ration cost with the restrictions on the indicators of overall nutritional value. The prototype of the application being developed is based on a functional model developed using the IDEF0 methodology, which defines the main functions of the system: processing user requests and providing the necessary information on animal feed and standards; creation of rations for animals according to set parameters; recalculation of a diet taking into account the changes made by the user; analysis of the diet and providing recommendations for its optimization. Methods for developing user interaction algorithms are described. To create an interface, design methods were chosen - "User-oriented design" and "Human-oriented design". When implementing the objectives of the current research, the problem of optimizing the diet of animals will be solved.
