  • 1 Identification/Definition of the Method

    /Baader, 1990/ section II, chap. 1.2 (here: "operational specification")

    2 Brief Characteristic of the Method

    The Mathematical Specification is a formal specification defining the behavior of operations by the description of pre- and postconditions.

    The postcondition describes the states that are allowed to be reached after the execution of the operation if the precondition was valid before the execution of the operation.

    3 Application of the Method in the V-Model

    The Mathematical Specification may be applied for the description of operations on every level of abstraction.

    4 Interfaces

    There are interfaces to DVER - Design Verification, PVER - Program Verification and ACC - Analysis of Covert Channels.

    5 Further Information

    - not applicable -
