What’s keeping you from using ProR in production?

The ProR tool already made an impact, both as the reference implementation of the ReqIF standard, and as an important puzzle piece for Eclipse-based Systems Engineering.  But we also know that there is still some work to be done, before ProR becomes fit for industrial use.  For

If you need to comply with ISO 26262, IEC 61508 or similar standards, you may need to work more formal

It’s quite impressive how safe cars, planes and trains are today.  Looking at this, it seems that we understand really well how to build reliable systems. This is in part due to safety standards.  When they are not followed, as it seems to have been the case

Using RMF to integrate your models

We’ve all seen it: You need to write a spec, so you open Word, write some text, you copy a state diagram from Enterprise Architect, and eventually send it off as a PDF. Okay, things are slightly better now. In the Eclipse ecosystem, maybe you are using

Reporting for ProR – We need your opinion!

ProR doesn’t yet support mature reporting features. Right now only a simple HTML-Version of a requirements document can be generated (you can access this via the print menu). A better visual representation of the requirements document has been requested many times by users. For instance, such a reporting

Use Cases with ProR

Use Cases are a popular method for recording requirements.  With little effort, ProR can make recording Use Cases easy and traceable. To demonstrate this, we use ProR itself as an example.  Below is a screenshot of ProR, recording the use case “Create a new SpecObject”.  You can

Data Validation & Reverse Engineering

At the core of the B-Method is a very expressive language rooted in predicate logic, set theory, relational calculus, higher-order functions and arithmetic. At the heart of our ProB toolset is an evaluator and constraint solver for this language. We strive for both efficiency and correctness, such that the
