Method for Assessing the Economic Efficiency of Digital Technologies in Dairy Farming Considering Changes in Process Parameters

The research develops a method for assessing the economic efficiency of digital technology in dairy cattle breeding. The research aims to improve the accuracy of predicting the effectiveness of these technologies and reduce the risks from unjustified decisions on the digitalization of this livestock production. The proposed method is based on the idea of estimating economic efficiency depending on the time cows spend in selected physiological states. The intensities of the process transition from one state to another are regarded as functions of the measures implemented. It is envisaged that some process parameters, in particular, yields from cows in selected states, change over time with age. It is proposed to consider the impact of digital technology on economic efficiency through changes in the intensity of process transitions from one state to another. According to the method, the process of the productive life of cows is described in the form of a graph of sixteen physiological states. A multistep resolution of the system of differential equations corresponding to this graph is provided to assess the economic efficiency of digital technologies for possible changes in process parameters. The simulation results confirm the possibility of obtaining more accurate estimates of the economic efficiency of digital technologies in dairy cattle breeding primarily due to a more complete accounting of the specifics of the analyzed process.
