% SOLVER_SSA_ANALYZER_NRM  Performance indices from SSA/NRM simulation
%   This variant runs the next‑reaction–method SSA on the network SN and
%   returns mean throughput (XN), utilisation (UN), queue length (QN),
%   response time (RN), throughput per station (TN) and class residence
%   time (CN).  Results are based on the empirical state probabilities
%   obtained from SOLVER_SSA_NRM.
%   *** Only stations whose scheduling policy is INF, EXT or PS are
%   supported. Any other policy triggers an error. Cache nodes are not
%   supported in this simplified variant. ***
