Modelling Activities in the Development Process Sample Clauses

Modelling Activities in the Development Process. 4.2.1. Modelling of BepiColombo SIXS/MIXS OBSW Requirements In the WP3 pilot deployment (see [RD5]), SSF created Event-B models for a considerable subset of requirements of the OBSW, with focus on handling of telecommands and on production of telemetry packets, i.e., on application of PUS (Packet Utilisation Standard, see [RD1]). While modelling in Event-B we had to clarify certain requirements. As a result of spotting certain ambiguities the requirements were changed. Though it is hard to assess whether the thorough requirements inspection would have had the same impact, we can certainly say that DEPLOY has facilitated requirements engineering of the OBSW. After the initial modelling several other modelling attempts were undertaken (see [RD6]). At that phase, no new requirement was modelled and no feedback to requirement authors got produced. Instead, the focus was on trying to construct better models by utilising the modular and decompositional extensions (see [RD7]) of the Event-B language. Modelling with the modular extension was done by SSF, whereas modelling with the decompositional extension was done by Southampton. The work on the modular modelling produced a useful tool feedback that allowed the developers to improve the tools as well as analyse different approaches to using modularisation in Event-B development. Development of OBSW has demonstrated that for some systems modelling of dynamic behaviour poses the main challenge. For instance, OBSW does not have complex safety constraints represented by the corresponding invariants. This was not surprising for modellers at SSF because a typical software requirement expresses what the software should do in a given situation. Events alone suffice for modelling such requirements. Invariant-like higher-level requirements may exist but may consider equipment in a way that the implications to the software are “shallow” or too abstract or beyond the scope of software requirements. Formal modelling of the systems similar to OBSW should be more focused on reasoning about liveness-type of properties. For instance, at the second phase of the project we have experimented with using UPPAAL tool to analyse dynamic behaviour and timing aspects of OBSW. Modelling of Attitude and Orbit Control Systems For the enhanced deployment phase, SSF has decided to experiment with a system that has a richer set of safety properties. The requirements for the case study were written in the Ada programming language. In that way, a...
