Optimization of Power and Economic Indexes of a Farm for the Maintenance of Cattle

Abstract

The concentration of plenty of animals in one building as it is stipulated by standard projects of large cattle-breeding complexes. It demands much of parameters of a microclimate, even to short-term variations. It can lead to greater economic losses. The main principles of system analysis in the design of general exchange ventilation and air conditioning systems are recommended to be air conditionings at design of systems of a microclimate of farms (SMF). The main communications between the systems intended for maintaining of the normalized parameters of the air are revealed. Initial conditions, for the purpose of identification of those which define functioning of a system are defined. We consider a system for the targeted selection of competing variants of subsystems. The principles of the decomposition of subsystems are determined based on the analysis of their totality as a whole. The initial basis for the construction of a mathematical model is being formed. In problems of optimization of heat exchangers and heat exchange systems the following main stages are allocated for design stages: bulk analysis of problems of optimization is made; the criterion of effectiveness is defined; the operating variables are chosen and it is tested their influences on criterion of optimization; the mathematical model of the device or process is formed; the strategy of a research of model and a method of searching of an extremum, criterion of optimization and carrying out optimum calculation is chosen. The creation of the mathematical model of the studied object is one of primal problems of optimum projection. The mathematical model of a system arises on rather a high level of abstraction of real systems. On the basis of this mathematical model, the algorithm and the computer program for the calculation are developed, allowing to optimize the basic constructive, technological and power parameters of system.
