Link State Routing Development from Hoang, Thai Son and Basin, David and Kuruma, Hironobu and Abrial, Jean-Raymond.
Redevelopment of an Industrial Case Study Using Event-B and Rodin from Rezazadeh, Abdolbaghi and Butler, Michael and Evans, Neil.
CDIS is a commercial air traffic information system that was developed using formal methods 15 years ago by Praxis, and it is still in operation today. This system is an example of an industrial scale system that has been developed using formal methods. In particular, the functional requirements of the system were specified using VVSL -- a variant of VDM. A subset of the original specification has been chosen to be reconstructed on the Rodin platform based on the new Event-B formalism. The goal of our reconstruction was to overcome three key difficulties of the original formalisation, namely the difficulty of comprehending the original specification, the lack of any mechanical proof of the consistency of the specification and the difficulty of dealing with distribution and atomicity refinement. In this paper we elucidate how a new formal notation and tool can help to overcome these difficulties.
