which can be solve to find ''π''<sub>0</sub> and ''π''<sub>1</sub> and therefore iteratively all the ''π''<sub>''i''</sub>.
==Matrix analytic method==
{{Main|Ramaswami’s formula}}
The '''matrix analytic method''' is a more complicated version of the matrix geometric solution method used to analyse models with block [[M/G/1 queue|M/G/1]] matrices.<ref>{{cite doi|10.1002/9780470400531.eorms0631}}</ref> Such models are harder because no relationship like ''π''<sub>''i''</sub> = ''π''<sub>1</sub> R<sup>''i'' – 1</sup> used above holds.
