This paper deals with a new approach to the modelling of socioeconomic systems. In these models, there are many interacting entities (agents, players). The whole market comes up as a result of these interactions. In terms of the economy, this concept is based on the Subject-Need-Good triad. The subject in this model represents an economical subject with needs that can be satisfied by the consumption of a good. In terms of computational modelling, this concept is based on the Discrete Event System Specification (DEVS) formalism, where each subject is represented by one coupled DEVS. This coupled DEVS contains several atomic DEVS. There are only three types of atomic DEVS – generator/store, transformer and optimiser. The basic process of the concept is the transformation that changes one type of a good to another or uses a good to satisfy a need. This experimental frame will be used for the design and development of a new dynamic approach based on dynamic Petri nets.
