The efficiency of multi agent system design mainly relies on the quality of a conceptual architecture of such systems. Hence, quality issues should be considered at an early stage in the software development process. Large systems such as multi agents systems (MAS) require many communications and interactions to fulfil their tasks, and this leads to complexity of architecture design (AD) which have crucial influence on architecture design quality. This work attempts to introduce approach to increase the architecture design quality of MAS by minimizing the effect of complexity.
