7AM (Factory Sourcing 4.0)
The project aims to develop a automatic process to find the most suitable manufacturers for companies world wide.
ADEPT1 - Flexible Workflow Management
The ADEPT project covered the main research area s of the institute from 1997 to 2003. ADEPT was not just a single project but a set of interrelated, complementary research activities aiming at next generation workflow management technology. With ADEPT1 a powerful proof-of-concept prototype had been implemented in this project. In particular, ADEPT1 was used by many research groups world-wide to implement flexible and adaptive process-aware applications. In 2004 we decided to start our work on the ADEPT2 technology which comprises additional features and provides an integrated implementation of them (see projects ADEPT2 and AristaFlow)
ADEPT2 (Next Generation Process Management Technology)
If current process management systems shall be applied to a broad spectrum of applications, they will have to be significantly improved with respect to their technological capabilities. Particularly, in dynamic environments it must be possible to quickly implement and deploy new processes, to enable ad-hoc modifications of running process instances on-the-fly (e.g., to dynamically add, delete or move process steps), and to support process schema evolution with instance migration (i.e., to propagate process schema changes to already running instances if desired). These requirements must be met without affecting process consistency and by preserving the robustness of the process management system. In the ADEPT2 project we address these challenges in an integrated way and provide a powerful proof-of-concept implementation of a high-end process management system. Our overall vision is to provide a next generation process management technology which can be used in a variety of application domains.
ADEPTdistribution (German Research Foundation; 1999 - 2001)
In this project we developed a comprehensive approach for achieving scalability in (distributed) workflow management systems. This includes advanced techniques and algorithms for workflow schema partitioning and distributed workflow control.
ADEPTevolution (German Research Foundation; 2001 - 2004)
In this project we realized a comprehensive and powerful approach for workflow schema evolution and change propagation in adaptive workflow management systems.
One major project goal of this project was to realize a software environment, which supports the component-based development of adaptive, process-aware enterprise applications in a "plug & play" like fashion. For this we have provided and implemented an adaptive process management system which offers a degree of flexibility and adaptability that goes far beyond the capabilities of current workflow management systems. This process management system has been based on the ADEPT workflow technology (see projects ADEPT1 and ADEPT2). Particularly, the offered functionality allows to develop process-aware information systems orders of magnitudes faster and with much more built-in flexibility than today. Another and probably the most important project goal was to provide this kind of development and execution environment to the industrial partners who use it as platform for application development and for realizing new kinds of enterprise software.
casavi (A Platform for flexible Real Estate Processes and Services)
The casavi project, which is funded by EXIST, strives for providing exactly a digital communication platform for multi-family properties. Comparable communication platforms are well known in other areas of living like online banking or travelling.
In this project we developed a change framework for organizational models as well as access rules as known from information systems. In particular, the developed CEOSIS framework considers all phases of the lifecycle of organizational models and access rules.
Corepro (Data-driven Process Structures)
Coordinating complex process structures is a fundamental task for enterprises. Such process structures have in common, that they consist of hundreds up to thousands of interdependent processes forming large process structures. Engineering a car, for example, requires the coordination of development processes for hundreds of components. Each of these development processes itself comprises a number of interdependent processes for designing, testing, and releasing the respective component. Typically, the resulting process structure is data-driven; i.e., it is characterized by a strong relation with the assembly of the product. We utilize this relation for automatically creating process structures based on data structures. The strong relation is used for adapting process structures at a high level of abstraction. Further, we provide exception handling mechanisms for managing dynamic adaptations. Altogether, COREPRO provides a new paradigm for IT support which reduces efforts for modeling and dynamic adaptation of data-driven process structures significantly.
DYCHOR (DYnamic CHOReographies)
Process-aware information systems have to be frequently adapted in order to deal with business process changes in the real world. One important challenge not adequately addressed so far concerns the evolution of process choreographies, i.e., the change of interactions and message exchanges between the partner processes in a cross-organizational setting. If respective modifications are conducted in an uncontrolled manner, inconsistencies or even errors (e.g., deadlocks) might occur in the sequel. In particular, modifications of private processes performed by a single party may indirectly affect the implementation of the private processes of partners as well. In the DYCHOR (DYnamic CHOReographies) project we elaborate a framework for coping with this fundamental challenge. DYCHOR allows process engineers to detect how changes of a private process may affect its related public view and - if so - how respective changes can be propagated to the public as well as the private processes of partners. To achieve this, DYCHOR exploits the formal semantics of the applied changes and automatically determines the adaptations becoming necessary for the partner processes. As proof-of-concept the main ideas of DYCHOR have been prototypically implemented. Altogether, DYCHOR provides an important contribution towards the realization of adaptive, cross-organizational processes.
EcoPost (Cost Estimation Methodology for Process-oriented Software Technologies and Process-aware Information Systems)
Introducing process-aware information systems (PAISs) is usually associated with high costs. It is therefore crucial to understand those factors that determine or influence these costs. Though software cost estimation has received considerable attention during the last decades, it is difficult to apply existing approaches to PAISs. This difficulty particularly stems from the inability of these methods to deal with the dynamic interactions of the many technological, organizational and projectdriven cost factors which specifically arise in the context of PAISs.
Picking up this problem, in the EcoPOST project we are developing a framework to investigate the complex cost structures of PAIS engineering projects through qualitative cost evaluation models. In this context we introduce cost evaluation models as well as rules and guidelines for their design. Respective evaluation models also reflect on results we gathered through empirical and experimental research. Altogether our EcoPOST framework provides an important tool supporting PAIS engineers in gaining a better understanding of the critical factors determining the costs of PAIS engineering projects.
ENPROSO (Enhanced Process Management through Service Orientation)
An important goal of any Service-oriented Architecture (SOA) is to increase the flexibility of IT-supported business processes. In particular, it should be possible to quickly implement new business processes and business services, and to flexibly adapt the corresponding IT applica-tions to changing business needs. In addition, it is crucial to adequately cope with changes in the SOA environment itself. Examples of such changes include modifications of IT services or business objects that are used by IT-supported business processes.
MinAdept (Mining Process Variants & Process Changes)
So far, adaptive process management technology has not addressed the fundamental question what we can learn from process instance changes and how to derive optimized process models from this information. Process mining techniques offer promising perspectives, but have focused on the analysis of pure execution logs so far. The MinADEPT project will close this gap and provide a comprehensive approach for the intelligent mining of adaptive processes.
In this project we delevoped a sophisticated approach for determining the impact each web service (of a composite service) has on the composition at runtime. More precisely, MoDe4SLA is able to identify complex dependencies between Service Level Agreements (SLAs) in a service composition. By explicating these dependencies, causes of SLA violations of a service can be explained by malfunctioning of the services it depends on. MoDe4SLA assists managers in identifying such causes.
niPRO (Personalized and Intelligent Process Portals)
The goal of the niPRO project is to use innovative semantic technology to integrate relevant process information in intelligent, user-adequate process information portals (also denoted as process cockpits). A niPRO process cockpit shall supply knowledge workers with both structured and unstructured process information in the right place in due course. Thereby, structured process information is typically provided by enterprise information systems by means of logged execution data. Examples of unstructured process information include textual process descriptions, procedural requirements, forms, guidelines, and checklists.
Periodicity in Information Systems (German Research Foundation, 2006 - 2007)
Periodicity is a wide spread phenomenon in real world and common in a large number of applications from different domains (e.g. finance and healthcare). In this research project all aspects related to the operational support of periodicity in information systems were systematically investigated and powerful solution approaches were developed.
The need for more flexiblity of process-aware information systems (PAIS) has been discussed for several years and different approaches for adaptive process management have emerged. Only few of them provide support for both changes of individual process instances and the propagation of process type changes to a collection of related process instances. The knowledge about changes has not yet been exploited by any of these systems. To overcome this practical limitation, PAIS must capture the whole process life cycle and all kinds of changes in an integrated way. They must allow users to deviate from the predefined process in exceptional situations, and assist them in retrieving and reusing knowledge about previously performed changes. If similar instance deviations occur frequently, process engineers should be supported in deriving improved process models from them. This, in turn, allows them to evolve the PAIS over time as well as the knowledge about the changes. In ProCycle we develop a next generation PAIS, which provides integrated and seamless process life cycle support. ProCycle combines the ADEPT2 framework for dynamic process changes with concepts and methods provided by case-based reasoning (CBR) technology like CBRFlow.
Proviado (Process Visualization in the Automotive Domain)
Today business processes are characterized by a high degree of distribution what makes it difficult to keep track of their progress. Proviado aims at providing an integrative presentation of processes whose activities are distributed among several systems and include steps that are carried out within legacy systems or even done by hand. The visualization will be personalized taking into account the user’s needs regarding the level of detail. Another goal is giving users an overview of the processes running in a distributed environment and monitoring the status. The knowledge gained will be transfered to the industrial partners by an implemented tool allowing us to present complex processes using recent internet graphic formats.
Provop (PROcess Variants by OPtions)
Provop deals with advanced issues related to the configuration and management of process variants. It provides full life cycle support and allows for flexible process configuration resulting in a maintainable collection of process variants.
In this project we developed a comprehensive framework evidencing the existence of activity patterns for defining recurrent business functions within process models. Furthermore, we investigated the benefits and completeness of these activity patterns with respect to business process mode
Q-ADVICE (Quality ADVisory Infrastructure for Collaborative Engineering)
Using applied research and new perspectives, this project will enable the benefits of automated software engineering to be used in conjunction with software quality management, thereby bringing software development processes to a new level. A powerful proof-of-concept prototype will be developed using the AristaFlow BPM Suite.
Qube (Quality Assessment and Management in Business Process Design, Implementation and Enactment)
SeaFlows (Supporting Business Process Compliance Along the Process Lifecycle)
Our objective in the SeaFlows project is to devise a general framework for supporting business process compliance along the complete process lifecycle.
SOPHINA (Software Products and Processes with Integrated Variability Support)
The SOPHINA project targets at a holistic approach that manages the variability of software products and software development processes in an integrated manner, considering all phases of the product and process lifecycle. In particular, SOPHINA will allow tracing variability across the various artifacts created during the software development process. Finally, a controlled evolution of software products, processes and related artifacts shall be enabled. As major application domain, SOPHINA considers the development process of the software for interdependent electric / electronic components in the automotive domain.
SustainHub (Sustainability Data Exchange Hub)
Funded by the 7th Framwork Programme of the European Commission, SustainHub is a collaborative project encompassing 15 partners from seven European countries. SustainHub is supposed to proved a network solution and efficient approach to collect sustainability data for products and processes along the supply chain. Thereby the management of sustainabilty data in the supply chain will be facilitatedas well as the eco-efficiency of products and production processes will be increased.
