Trends in BPM Research (Sommersemester 2016)

Dozent: Prof. Dr. Mathias Weske (Business Process Technology)
Tutoren: Dr. Luise Pufahl

Beschreibung

Business process modeling (BPM) is a well-established method in industry to capture business processes of an organization for documentation, implementation, monitoring and improvement purposes. In our group, we develop methods, concepts and tools to support and improve this area, e.g. by integrating batch processing into business processes. Further, we look into related research areas (see the figure below) and investigate in how far business process modeling can benefit from other research.

In this course, we want to present you current research trends in BPM and want to give you insights into the work of researchers. You will get to know techniques for approaching research topics. This can give you support in defining own research topics, e.g. for your master thesis.

 

(1) Batch Processing in Business Processes: In existing business process models, it is assumed that the executions of a process model, i.e. the process instances, run totally independently from each other. However, in certain situations a synchronized execution of a group of process instances, called batch execution, can improve the process performance. For example, if an online retailer receives two orders from one customer, there is a chance that they can be packed and shipped together to save shipment costs. In the first part of the lecture, we will have a look into approaches to realize batch processing in business processes, especially at an approach developed by the BPT group integrating batch activities in process models.

(2) Process Models and Decision ModelProcesss: A company's value chain is directly affected by how well it designs and coordinates enterprise decision making. Therefore, we present decision modeling complementary to business process modeling. Coupling the two disciplines comes with various challenges. For instance, the interplay of decisions and processes must be consistent. Hence, we will introduce a set of consistency criteria and different methods for checking them. Additionally, decision-aware compliance checking verifies semantic properties of business processes while considering complementary decision logic. In this part of the lecture, you will learn about formalization of processes and decisions, model checking methods, and symbolic data abstractions. Further, you will see how these techniques are applied for compliance checking.

(3) Fragment-Oriented Case Handling: One of the main drivers in BPM research is to increase the flexibility of the processes that can be modeled and supported by process management systems. Case Management is one recent example which aims at supporting knowledge work, in which the course of the case evolves during its execution, depending on data objects and user decisions. In this part of the lecture, you will encounter the case management model and notation (CMMN) standard, artifact-centric process modeling approaches, and declarative process modeling. This will culminate in the hybrid approach of dynamically combined process fragments that was developed at our group and implemented during the last bachelor project as Chimera framework.

(4) Use Events to implement Business Processes: Business processes today are often run in a distributed environment with several participants. Events are a form of message/signal exchanges between the partners. Also, processes can receive events from external sources like a sensor or a traffic API. The information carried by the events are then used to improve the flexibility or decision making of the process. An event processing platform connects to different event sources, operates on event streams and notifies the event consumers about specific event occurrences. However, there are various aspects to consider while using events in business processes, for example, event binding, event subscription, event correlation or event timestamps. This part of the lecture will focus on such issues and the current state of research in the area of complex event processing.

(5) Choreographies and their RESTful Implementation: Today, business process management is a key approach to organize work, and many companies represent their operations in business process models. Recently, choreography diagrams were introduced to represent interactions between business processes, run by different partners. While there is considerable work on using process models during process implementation, there is little work on using choreography models to implement interactions. In this part of the lecture, we focus on a novel approach to enhance choreography diagrams by execution information. The approach is based on the REST architecture style. This is the primary way for communication between interacting systems.
