document: Dual nature of mass multi-agent systems Dual nature of mass multi-agent systems -LRB- mMAS -RRB- emerging as an internal discord of two spheres - micro -LRB- virtual -RRB- consisting of agents and their internal phenomena , and macro arising at the interface to the real world $ stems the necessity of a new approach to analysis , design and utilisation of such systems . Based on the concept of VR decomposition , the problem of management of such systems is discussed . As a sub-type that makes mMAS closer to the application sphere , an evolutionary multi-agent system -LRB- EMAS -RRB- is proposed . EMAS combines features of mMAS with advantages of an evolutionary model of computation . As an illustration of this consideration two particular EMAS are presented , which allow us to obtain promising results in the fields of multiobjective optimisation and time-series prediction , and thus justify the approach
