Pract. Exp. 24, No. 16, 1879-1902 (2012).} \itemab Summary: We present a new method to assign tasks, which are connected by time dependencies within a heterogeneous environment, (e.g., several resources communicating with each other). Our approach for task distribution uses an artificial hormone system, which is self-organizing and able to meet real-time constraints. Several enhancements to the artificial hormone system have been made, such as partial suppressing of tasks and distributed task termination. \itemrv{~} \itemcc{} \itemut{multi-stage hormone based control loops; real-time task allocation; organic computing; self-organization} \itemli{doi:10.1002/cpe.1815} \end
