An Introduction to the Event-B Modelling Method
Event-B [2] is a modelling method for formalising and developing systems whose components can be modelled as discrete transition systems |
|
The Event-B Modelling Notation
The primary concept in doing formal developments in Event-B is that of a model A model contains the complete mathematical development of a Discrete |

Formal Modelling of Ontologies : An Event-B based Approach Using
An Event-B model is characterised by a set of variables defined in the VARIABLES For example |
|
Events A and B are independent if: knowing whether A occured
Example. Throw 2 dice. A first die lands 1. B second die shows larger number (a) In a fully-specified math model two events are either dependent or. |

Probabilities of outcomes and events
As an example if A is the event that it rains today and B is the event that it models can assign different probabilities to the same set of events. |
