I am trying to rank critical variables for Enterprise system's various  life cycle stages.

Hence I need to conduct  Ranking of variables via ANN in SPSS

In my data every variable is graded on a likert scale (1-5) and then its given either 1 or 0 weight for each life cycle stage.

(a) Plz advise how to first conduct  weighted grading  of each variable?

(b) Then how to decypher ANN based ranking in SPSS?
