Algebra Control Optim. 2, No. 1, 45-56 (2012).} \itemab Summary: Extending the longevity of autonomous agent system in real life application is a difficult task, especially in applications which require continuous high system performance. This paper presents a novel decentralized balancing controlling architecture for longevity and achievement in multi-agent robot systems based on several artificial immune systems (AISs) designs and principles. Simulation experiments have verified that the proposed architecture has good capability to efficiently minimize the trade-off in system achievement while maintaining system sustainability, even in very demanding situations. \itemrv{~} \itemcc{} \itemut{artificial immune systems (AISs); multi-agent system; multi-robot system; longevity; achievement optimization} \itemli{doi:10.3934/naco.2012.2.45} \end
