Design patterns in multi-agent system simulation

Building system software is hard. It is necessary to have a methodology to achieve good systems. Presently, there are a few methods for developing multi-agent-based systems. Taking experience of solutions that worked well in the past is the main purpose of the design patterns, which were found in designing object-oriented software. In this work, we present three design patterns that could be used for developing multi-agent-based systems. We made a high level design using these patterns and the design was applied to an emergency evacuation system. We measured the flexibility and extensibility of the design using the instability and abstraction metrics.
