  We develop an interface-modeling framework for quality and resource
management that captures configurable working points of hardware and software
components in terms of functionality, resource usage and provision, and quality
indicators such as performance and energy consumption. We base these aspects on
partially-ordered sets to capture quality levels, budget sizes, and functional
compatibility. This makes the framework widely applicable and domain
independent (although we aim for embedded and cyber-physical systems). The
framework paves the way for dynamic (re-)configuration and multi-objective
optimization of component-based systems for quality- and resource-management
purposes.
