Development of Information System for Optimization of Cattle Rations
This research is aimed at solving an important problem of agricultural production and livestock production in particular - optimization of rations of cattle to increase productivity and reduce the costs of the enterprise. The use of information systems in the compilation of a diet will help accelerate the process of compilation and minimize the standard errors allowed by a specialist in animal technician, which will have a positive effect on the quality and quantity of the products. Studies of existing information systems for optimizing animal rations have been carried out, and their shortcomings have been identified. To formulate requirements and evaluate existing systems, the ISO 9126 quality model has been selected. A mathematical model of methods for optimizing rations based on linear programming has been developed. The solution of the optimization problem of linear programming will be produced by the simplex method, whose task is to minimize the objective function at the cost of the composted diet and with a number of limitations on the indicators of general nutrition. At the heart of the developed prototype applications the functional model has been incorporated which is developed using the methodology of IDEF0, which defines the basic functions of the system: processing user requests and providing the necessary information on the feed and animal standards; creation of rations for animals according to the given parameters; recalculation of the ration taking into account the changes made by the user; analysis of the diet and providing recommendations for its optimization. The interaction of the connected libraries is described. Methods for developing algorithms for interaction with the user are described. To create an interface, the design methods are chosen - "User-oriented design" and "Human-oriented design". Thus, in the implementation of the tasks of this study, the problem of the rate of optimization of the diet will be solved.
