Umsetzung ausgewählter Methoden für die quantitative und qualitative Analyse von mehrstufigen Geschäftsprozessen mittels XQuery: Ist- und What-If-Analyse der Duchlaufzeit sowie Fehler-Ursachen-Analyse

Business processes are usually spread over various levels of abstraction. This leads to the fact that often they cannot be represented adequately by using conventional process models. A Multilevel Business Artifact (MBA) combines both data and process models of different hierarchical levels in one object. The processes are defined as state charts using the W3C recommendation of State Chart XML (SCXML), which allows them to be executed semi-automatically by a process engine. This thesis describes the implementation of an XQuery module for analyzing multilevel business processes which have been modelled using MBAs, based on the logs produced during semi-automatic execution of the processes. Therefore, it reconstructs the lifecycles of MBAs using logs. On the one hand, the module calculates average cycle times of processes and states and on the other hand, it provides functions to identify weaknesses of processes.
