Executable Scenario Concept

Executable Scenarios (ExSce) are model-based narrative descriptions of robotic missions guiding the engineering of MRS applications. An ExSce supports the definition of scenarios, composed of mission-relevant and mission-plausible information. On the one hand, by mission-relevant information we refer to, among others, the environment and its dynamics, time and events, objects (e.g., inspected building) and subjects (e.g., human operators) and their potential behaviour. On the other hand, the mission-plausible information describes acceptance criteria that enable the verification and validation of MRS requirements. Both, mission-plausible and mission-relevant information are computer-interpretable models and hence enable the transformation into artefacts which can be executed in different contexts such as in simulators or on real robots.

Executable Scenario Methodology

To put the ExSce concept into action, the ExSce methodology enables the structured development of MRS from stakeholders’ scenarios. Hence, it comprises both a tailorable process model and associated tools that guide and support the stakeholders in (i) specifying scenarios; (ii) transforming them to executable artefacts; (iii) executing those artefacts; (iv) assuring the quality of the MRS in those scenarios; and (v) generalizing those scenarios.

Executable Scenario Workbench

The ExSce Workbench is a collection of tools that supports stakeholders in carrying out one or more activities of the ExSce Methodology.
