Many bureaucratic and industrial processes involve decision points where an object can be sent to a variety of different stations based on certain preconditions. Consider for example a visa application that has needs to be checked at various stages, and move to different stations based on the outcomes of said checks. While the individual decision points in these processes are well defined, in a complicated system, it is hard to understand the redundancies that can be introduced globally by composing a number of these decisions locally. In this paper, we model these processes as Eulerian paths and give an algorithm for calculating a measure of these redundancies, called isolated loops, as a type of loop count on Eulerian paths, and give a bound on this quantity.
