The type Period needs to be declared public because it must be available outside the Plant class. Guideline 7: Tokens are useful for abstract models where unspecified values are to be used. ✞ class Expert ... types public Qualification = | | | ; end Expert ✝ ✆ ✡ Qualification is an enumeration type. In VDM++, this is technically represented as a union (indicated by the vertical bars) of quote types (the identifiers in angle brackets). A quote type contains just one value, which has the same name as the type itself.

In addition to the drastic reduction in the time to construct an implementation, automatic code generation offers a number of benefits. Foremost among these is the strong correspondence between the abstract model and the generated code. This simplifies understanding of the code and its architecture. This also opens up the possibility of reusing test data originally used for testing the VDM++ model. It is possible that the algorithm used in the generated code is inappropriate in a particular instance, but in this case it is possible to generate code skeletons, which may then be handimplemented.

2 A Chemical Plant Example This section presents the requirements for a simple alarm system for a chemical plant. It forms a running example that serves to illustrate the process described earlier and to introduce elements of the VDM++ modelling language. Although the modelling process is described here as though it were a single-pass activity, a real development would usually be iterative. Furthermore, because the example used for our illustration here is small, step 3 from the list will be omitted entirely.
