Predictable Deployment and Configuration (D&C) of components in response to dynamic environmental changes or system mode changes is essential for ensuring open Distributed Real-time and Embedded (DRE) system real-time QoS. This paper provides three contributions to research on the predictability of D&C for component-based open DRE systems. The authors describe how the dependency relationships among different components and their criticality levels that can cause deployment order inversion of tasks, which impedes deployment predictability. They describe how to minimize D&C latency of mission-critical tasks with a multi-graph dependency tracing and graph recomposition algorithm called CaDAnCE.
