“…Altogether, this chapter comprises some fundamental concepts for implementating adaptive PMS. At the moment our ADEPT PMS prototype [90], which is currently used by several partners [10,11,81] as a platform for realizing advanced PAIS (e.g., supporting e-business and clinical workflows) is re-implemented within the AristaFlow project. This project is a cooperation between the Universities of Ulm and Mannheim and several companies (for details see [86]).…”

“…Criterion 8). Regarding subsumption equivalence between concurrent process type and process instance changes (on S) we have to distinguish two cases: (1) ∆ T is subsumption equivalent with ∆ I , i.e, ∆ I contains all effects of ∆ T on S and has additional effects (formally: ∆ T ≺ ∆ I ) or (2) ∆ I is subsumption equivalent with ∆ T , i.e., ∆ T includes the effects of ∆ I on S but has 10 Note that there is a conflict between the runtime performance of the PMS and the goal of migrating as many instances as possible. One possibility to increase the migration rate is to first check state-related compliance by verifying the state-conditions set out in Section 4.3.2.…”

Schema Evolution in Process Management Systems

Continuously arising new trends in information technology and developments at the (e-business) market let companies crave for automated business process support. Process management systems offer the promising possibility to (electronically) define, control, and monitor business processes. However, if this technology shall be applicable in practice it must be possible to change running business processes even at runtime. Basically, such process changes can take place at two levels -the process type level and the process instance level. If a process type is modified a new version of the respective process type schema is created. Then, at minimum, the process instances running according to the old process type schema version must be able to finish without being disturbed. However, this simple versioning approach is only sufficient for short-running business processes. For long-running ones like, for example, car leasing contracts or medical treatment processes which may last from 3 up to 5 years, it must be possible to apply the process type changes to the collection of running process instances as well but without causing inconsistencies or errors in the sequel. Apart from process schema evolution and change propagation a flexible process management system must also enable instance-specific (ad-hoc) changes, for example, if exceptional situations occur. If then a process type change takes place the challenging question arises how to adequately deal with the interplay of process type and process instance changes.

This thesis has been written during my work as a team member of the Department of Databases and Information Systems (DBIS) at the University of Ulm. The motivation for working on the project "Schema Evolution in Process Management Systems" stems from the fundamental approaches on e.g., process design, dynamic process changes, and distributed process execution already conducted within the ADEPT project as well as from experiences with many practical projects.First of all, I thank my supervisor Prof. Dr. Peter Dadam for his guidance and support throughout my whole "thesis process". The fruitful discussions with him exceedingly contributed to make this thesis a success. Especially his enormous knowledge on related work and his problem-oriented view ("What's the message?") saved me from missing the red line. Finally, he always motivated me in being able to do anything I want.Furthermore, I thank Prof. Dr. Franz Schweiggert who accepted to act as second referee. His comments on my work and the discussion with him were very important for my work and motivating for me. Special thanks go to Dr. Manfred Reichert. The numerous discussion with him always helped me in proceeding with the content of my work. It was a pleasure to work with him on our diverse publications. His indefatigable effort to improve the quality of publications is admirable. I also thank him for proofreading my thesis.I also want to thank the whole DBIS team for helping and motivating me during my whole time at the department. The friendly and collaborative atmosphere largely contributed to feel happy during working hours. Finally thanks go to all students who contributed to this work (especially Markus Lauer for the implementation of the proof-of-concept prototype, the fruitful discussion, and the proofreading of the algorithms).My best thanks go to my parents Evi and Hermann Rinderle, my brother Matthias, my sister Julia, and my partner Oliver. Their love and support have made this work possible.

Process-aware information systems will be not accepted by users if rigidity or idleness due to failures comes with them. When implementing business processes based on process management technology one fundamental goal is to ensure robustness of the resulting process-aware information system. Meeting this goal becomes extremely complicated if high flexibility demands need to be fulfilled. This paper shows how the AristaFlow BPM Suite assists process participants in coping with errors and exceptional situations in a flexible and robust way. In particular, we focus on novel error handling procedures and capabilities using the flexibility provided by ad-hoc changes not shown in other context so far.
