Hello Michael!
In Russian there is 1 textbook of my teacher Markuze where about reliability 0.5 pages but any analysis are written. Wolf Ghilani we have translated the small paragraph about reliability. There only how to calculate. Have translated the paragraph from book Niemeir Ausglechungrechnung... Too only calculations. A bit more but it is scattered under all book at Jäger Klassische und robuste... But about the analysis it is not enough. For example at us such problem: there are 4 points which of height it is necessary to define. We have 4 points with known heights (initial). Defined points and a part of the initial have connected measurements in 6 various networks. How under reliability characteristics to establish what network it is more reliable?
