Flaws in requirements may have unacceptable consequences in the development of safety-
critical applications. Formal approaches may help with a deep analysis that takes care of the …

Prototyping is an effective and efficient way of requirements validation to avoid introducing
errors in the early stage of software development. However, manually developing a …

Unsatisfiable cores, ie, parts of an unsatisfiable formula that are themselves unsatisfiable,
have important uses in debugging specifications, speeding up search in model checking or …

The system requirement specifications (SRSs) of the train control system (TCS) are the
starting point and foundation of system design and development. Defects in the SRSs will …

Development and application of formal languages are a long-standing challenge within the
computer science domain. One particular challenge is the acceptance of industry. This …

Requirements engineering plays a pivotal role in the development of safety-critical systems.
However, the process is usually a manual one and can lead to errors and inconsistencies in …

To analyse the behaviour of reactive systems formally, it is necessary to build a model. At the
very beginning of the development, typically only natural language requirements are …

Requirements validation is a crucial process to determine whether client-stakeholders'
needs and expectations of a product are sufficiently correct and complete. Various …

In software engineering, system requirements are written in a natural language such as
English. Later in the design phase, these requirements are usually translated to a semi …

One of the most important phases in software development projects is the validation of
requirements. Erroneous requirements, if not detected on time, can cause problems, such as …
