In this article a model of interaction of the two types of civilizations is considered. These two types of civilizations were conventionally called “nomads” and “plowmen”. Each type is characterized by its method of product reproduction, which is necessary for agents of both types. If plowmen reproduce product by using their skills, nomads reproduce nothing, instead they con-sume that resource which they find, including the resource they take away from plowmen and the other nomads. This product is also a resource; it is the main object of competition between the agents. It is the main reason for aggression of one group of agents towards the others. In addition to the product that is reproduced by plowmen, there is also a wild resource that appears in the range in randomly defined places with a given intensity. According to the author’s intention, the constructed model is a simplified model of the ancient world, in which each of the civilizations could be classified as one of the two considered types. Typical representatives of the civilization of plowmen are the civilizations of Mesopotamia, the front of Asia, Byzantine and Roman em-pires, etc. Classic nomadic civilization is represented by nomadic civilizations of the Great steppe. The model is implemented on the basis of the agent-based approach in the software pack-age AnyLogic. In this work a number of experiments have been conducted. In experiments the study has been made of how characteristics of coexistence of two types of the civilizations vary depending on the variation of considered parameters. Important parameters of the model, impact of which was studied, are the size of habitat and growth rate of the wild resource. Based on the obtained data, statistical and econometric analysis is conducted.
