Application of the multivariate depth-based method for ranking the performance of judiciary

Evaluating the performance and ranking of the judiciary of the provinces periodically is always of interest‎. ‎This problem can be done with univariate approaches; But considering many variables involved in this matter‎, ‎the use of multivariate methods is more justified‎. ‎A new method for this is ranking based on the depth concept‎. ‎In this paper‎, ‎the performance of prosecutors' offices‎, ‎criminal courts and appeals courts of the provinces have been ranked over one year based on two indicators; case processing rate and the case congestion rate‎, ‎employing the depth multivariate method‎. ‎Evaluating the results of ranking intuitively confirms the appropriateness and rationality of this approach.
