| Popis: | Networked embedded software systems incorporate varying degrees of adaptation behavior to sustain their operations with acceptable quality of service (QoS), in the face of hostile external events — such as resource outages in a cloud service, road slipperiness in a car driving, etc. For instance, a highly agile cruise control system of a car may dynamically adjust its controller parameters to generate a higher-than-normal increase in torque when encountering a higher road elevation (relative to a normal controller). With the high complexity of such dynamic adaptive systems, their QoS capability depends on how well they respond to hostile external events. The paper formulates model-based assessment techniques to reason about how capable is a networked system S in meeting its QoS specs. We benchmark the QoS capability of S by a stress-testing of S with artificially injected failures. As a case study, we describe the QoS assessment of a multi-vehicle adaptive cruise control system. |
