A Basis for feature-oriented modelling in Event-B
A Basis for feature-oriented modelling in Event-B
Feature-oriented modelling is a well-known approach for Software Product Line (SPL) development. It is a widely used method when developing groups of related software. Due to reuse methods, the development of the software product is quicker, less expensive and of higher quality. However, this approach is not common in formal methods development, which is generally high cost and time consuming, yet crucial in the development of critical systems. We present a method to integrate feature-oriented development with the formal specification language Event-B. Our approach allows the user to map a feature from the feature model to an Event-B component, which contains a formal specification of that feature. We also present some patterns, which assist the user in the modelling of Event-B components. We describe a composition process which consists of the user selecting an instance in the feature model and then constructing this instance in Event-B. While composing, the user may also discharge new composition proof obligations in order to ensure the model is consistent. The model is then constructed using a number of composition rules.

Abstract
Feature-oriented modelling is a well-known approach for Software Product Line (SPL) development. It is a widely used method when developing groups of related software. Due to reuse methods, the development of the software product is quicker, less expensive and of higher quality. However, this approach is not common in formal methods development, which is generally high cost and time consuming, yet crucial in the development of critical systems. We present a method to integrate feature-oriented development with the formal specification language Event-B. Our approach allows the user to map a feature from the feature model to an Event-B component, which contains a formal specification of that feature. We also present some patterns, which assist the user in the modelling of Event-B components. We describe a composition process which consists of the user selecting an instance in the feature model and then constructing this instance in Event-B. While composing, the user may also discharge new composition proof obligations in order to ensure the model is consistent. The model is then constructed using a number of composition rules.
