摘要

这篇文章描述了一种利用俄罗斯科学家开发的AnyLogic软件对食品市场进行建模的原始方法。作者提出了一个模拟2000年至2019年期间肉类和肉制品市场行为的系统动力学模型。结果显示,家禽、牛肉、猪肉等3种基本产品的消费价格趋于平衡。通过对这些市场消费者价格中期预测的计算,验证了仿真模型的可靠性。原来的模型说明了市场形势的历史动态。研究表明,粮食市场在进口保护水平、国家支持程度、竞争水平以及进入和退出壁垒等特征上变化很大。因此,回顾性调查揭示了食品市场这一部分(家禽、牛肉和猪肉)的产量增长率不稳定。因此,家禽市场充斥着替代进口产品的国产产品。同时,牛肉生产的低增长速度带来了对进口的依赖。所得结果可作为制定农业生产市场经济调控政策的工具。关键词:预测,系统动力学建模,食品市场,有效市场管理,AnyLogic

Forecasting Food Prices in the AnyLogic Information System
The article describes an original approach to modelling the food market with the use of the developed by Russian scientists AnyLogic software. The authors propose a model of system dynamics simulating the behavior of the meat and meat products market in the time period from 2000 to 2019. The acquired results include balance consumer prices for the three basic products: poultry, beef, and pork. The calculation of the midterm forecast of consumer prices in these markets confirms the reliability of the simulation model. The original model illustrates the historic dynamics of the market situation. The research shows that food markets are highly variable in such characteristics as the level of protection from import, the amount of state support, the level of competition, and the entry and exit barriers. As a result, the retrospective survey reveals a volatile growth rate of production volumes in this segment of the food market (poultry, beef, and pork). Thus, the poultry market is saturated with domestic products that have substituted imported goods. At the same time, the low growth tempo of the cattle meat production has brought to import dependence. The obtained results of the survey may be applied as tools for developing the economic regulation policy in the agro production markets. Keywords—Forecasting, systemdynamicmodelling, food markets, effective market management, AnyLogic
