Particularly, during refinement, the specification is complemented with the details that are unnecessary in the higher level specification.
It is important to remember that verification, while separate from validation, is intended to be performed in conjunction with validation.
The results of this analysis provided insights into PAMEX and identified errors in programming that the developers and users were unaware of.
This draft handbook will also be field tested in a number of States using operational expert systems as test cases.
Model checking is a technique for automatically verifying correctness properties of finite-state systems.
In order to solve such a problem algorithmically, both the model of the system and the specification are formulated in some precise mathematical language.
