Case cover

Criteria weighting and alternative matrix
Problem
Location, capacity, and investment are coupled; alternatives could not be compared without aggregating criteria into comparable scores.
Approach
Criterion weights fixed first, then light sensitivity runs. GRA reference series and normalized comparison matrices in Excel.
Technical Structure
Inputs
Population, student density, rent, competitor count, survey demand signals.
Criteria
Cost, access, demand, competitive pressure; each normalized to a common scale.
Method
GRA: reference ideal vector, grey coefficients, ranking. Weights sum to 1.
Decision output
Ranked alternative list and recommended PC-count band.
Outcome
Dominant location and capacity band reported; assumptions and weights explicit in the write-up.
