This paper builds upon our previous work in which we proposed an architecture and a general optimization framework for dynamic, distributed real-time systems. Interesting features of this model incude the consideration of adaptive applications and utility functions. We extend our earlier work by formalizing the corresponding multi-criterial optimization problem. As the most difficult part of this problem we identified the evaluation and comparison of the quality of single allocations and sets of allocations, respectively. To this end, we propose and examine metrics for measuring the goodness of solutions within our general resource management framework. These metrics lay the basis for further work on developing both online and offline algorithms to tackle the general optimization problem and provide an efficient adaptive resource manager for dynamic distributed real-time systems.
