Agent-Oriented Methodologies presents, analyzes and compares the most significant methodological approaches currently available for the creation of agent-oriented software systems. The chapters of this book each address the details of one specific agent-oriented methodology, written by the original methodology creators. They highlight the methodology details and also the strengths and motivation. Each chapter also notes any purposeful omissions and weaknesses and each ends with a small case study to exemplify the application of the methodological approach. Agent-Oriented Methodologies offers the use of a method engineering approach based on the OPEN Process Framework (OPF) to bring together these potentially disparate methodological approaches to sustain the methodology developers and researchers use in creating a more holistic approach that will be suitable for adoption by industry software developers.
