Setting a task of modelling.There is a cattle herd structured on the basic of age.The daily increase depends in weight of an animal which defines the weight of it depends on the age.Only the quantity which is enough for reproduction of the herd.The similar situation is with heifers.It is required to model the change of an annual turnover of the herd and its reproduction.Farm (Farm) which describes the structure of the model.Norms and diets of feeding are defined in it.Herd, describing variable statuses and dynamics of behaviour of the herd as a whole.The important component which defines the structure of the herd, its internal interaction.
