It is possible to analyze the processes in Allura Xper systems from various angles. The concept of a “case” (i.e., process instance) may refer to a machine, a machine day, the execution of a particular procedure, the repair of a machine, etc. Figure 12.11 shows an example taken from [51]. Processes discovered for these sys-tems tend to be Spaghetti-like. To simplify diagnosis, the log is often preprocessed as discussed in [12–14]. Moreover, fuzzy mining, as illustrated by Fig. 12.8, is used to further simplify the model [51].
