SMM11 — interval-based mapping

Open Closed All
  • Key: SMM11-135
  • Legacy Issue Number: 17535
  • Status: closed  
  • Source: VDMbee ( Mr. Henk de Man)
  • Summary:

    A ranking in SMM results in a mapping to symbolic value (a string), which is unit-less, and which does not allow to be used as factor in further measure-based computations.
    It is required that similar interval-based mapping can also be used to result in a dimensional measurement, the value of which is numeric.

    Proposed changes:
    Rename SMM Ranking into GradeMeasure
    Rename SMM Grade into GradeMeasurement
    Rename RankingInterval into GradeInterval.
    Add another measure, called RankingMeasure (specialization of DimensionalMeasure); It has associated RankingInterval (very much like the existing ones)
    Ranking intervals of RankingMeasure have a numeric value instead of a symbolic string value.
