Formal modeling towards a dynamic organization of multi-agent systems using communicating x-machine and z-notation

Abstract

The real world is a dynamic place where things change in an unexpected way. Software must be able to adapt these changes to work efficiently in the real world. Modeling of the multi-agent system implies modeling of the agent's dynamic structure and behavior, including their ability to communicate with other agent of the systems and dynamically organize their formation over time. In this research we used two different formal methods, communicating stream X-machine and Z notation, for writing the formal specification of multi-agent systems with a dynamic structure and behavior. Both the modeling techniques possess different characteristics which are discussed through the modeling process of multi-agent system. A case study of biologically inspired multi-agent system is taken to illustrate the proposed modeling approach. © Indian Society for Education and Environment (iSee).
