Model Animation

Overview

The most important additions of the last 12 months are:

Application of ProB in three active deployments, namely the upgrading of the Paris Metro Line 1 for driverless trains, line 4 of the S\~{a}o Paulo metro and line 9 of the Barcelona metro. We also briefly report on experiments on the models of the CDGVAL shuttle. The paper ^[1] only contained the initial San Juan case study, which was used to evaluate the potential of our approach.
In this article we describe the previous method adopted by Siemens in much more detail, as well as explaining the performance issues with Atelier B.
Comparisons and empirical evaluations with other potential approaches and alternate tools (Brama, AnimB, BZ-TT and TLC) have been conducted.
We provide more details about the ongoing validation process of ProB, which is required by Siemens for it to use ProB to replace the existing method.

The validation also lead to the discovery of errors in the English version of the Atelier B reference manual.

Also, since ^[2], ProB itself has been further improved inspired by the application, resulting in new optimisations in the kernel (see below).

Rodin 10 Paper

Lukas Ladenberger's Master's thesis

mainly inspired by Siemens and Bosch Applications

Improved AVL algorithms, more operators

record support, treatment of infinite sets,

The above works were motivated mainly to support the following three industrial deployments:

Siemens: enable Siemens to use ProB in their SIL4 development chain, replacing Atelier B for data validation.
Bosch: provide animation and constraint-based deadlock detection for the Adaptive Cruise Control
SAP: provide a way to generate test cases using constraint-based animation
