Economic models of calculation, planning and decision-making in hop growing

Abstract. The purpose of the research is to study the main global instruments that create broad opportunities for planning and decision-making in hop growing by structuring and systematizing them. The advantages of the models are taken into account when developing the structure of our own economic model for calculating planning and decision-making in hop growing. Research methods are a monographic study and analysis of financial and economic indicators of hop growing in different countries based on a study of foreign models for calculating the efficiency of the industry, namely: 1) Pennsylvania State University (USA); 2) Washington State University (USA); 3) a joint model of Michigan State University and the University of Vermont (USA) and 4) a model from the Slovenian Institute for Hop and Brewing Research. Based on the research, a schematic representation of the algorithms for the operation of the models was formed. Block diagrams of the main processes of the Russian model for planning and decision-making in domestic hop growing developed by the authors are presented. Scientific novelty. The economic model of planning and decision-making in hop growing through modeling presented by the authors will be the first such model in Russia. For comparison, in Europe a similar model for hop growers was developed back in the 90s of XX century, in the USA, models exist in various variations and are formed for different scales of activity and areas of hop plantings: from 2 to 250 hectares. Results. The inclusion of double calculation in the developed model radically distinguishes the created Russian model from all the approaches analyzed above and is a fundamental advantage, since it makes it possible to conduct a separate assessment of both cash flows, including capital investments, and the economic results of the efficiency of the activity of an economic entity – a hop grower. At the same time, two separate types of calculations are presented in a single model, which will provide a complete picture of the company’s financial condition for both external users and the business owner.
