    Approach to learning production rules for grammar-based functional design
    (Informatik 2014, 2014) Eichhoff, Julian R.; Roller, Dieter
    This paper outlines the problem of efficiently formalizing functional design rationale in form of graph-rewriting production rules. It is argued that genetic programming provides a feasible machine learning approach to this.

    BPMN process design for complex product development and production
    (Informatik 2014, 2014) Roller, Dieter; Engesser, Erik
    In automotive development a lot of new power engine concepts were developed. Beneath the combustion engines hybrid drive systems and electric engines were developed. Consumers, public institutions and politics demand alternative drive systems to avoid air pollution, noise and the consumption of oil resources. Therefore electric drive products with innovative technologies were developed additionally. The problem for production plants is to today how these new technologies can be produced additionally to the existing cars with combustion engines. The objective of this paper is to design processes for complex product development with a lot of product variants an production processes which have to produce the complex product variants. The approach is to use BPMN 2.0 (Business Process Modelling Notation) to model the processes between development and production. BPMN 2.0 supports graphical process modelling and executable process modelling. The consequences of complex product development with high alternative drive systems to production lines were analyzed by BPMN models. A further approach is to use the research tool PROCAS (Process Optimization, Control, Analysis and Simulation) to analyze the consequences of high product variants in production. PROCAS use information of existing CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) systems. The concept of PROCAS is to determine how existing plants, production lines and inventories have to be extended.

    Cooperative CAD system for conceptual-embodiment design phase of product design
    (Informatik 2014, 2014) Hasby, Fariz Muharram; Roller, Dieter
    In the modern globar market and manufacturing environment, industries have to put more focus on reducing time to market while reducing production costs on the development of new products. Collaborative product development is a growing trend that is being used to answer some of that problem. However, literature research has revealed that there are only a small number of researches that has talked about cooperative CAD systems. This paper will try to show that this type of system can be used in the conceptual-embodiment design phase while encouraging creative solutions from the designers involved. It will also list some functional requirements and areas of interest for these type of system that has been identified by this research at the time of writing.

    Intelligent requirement analyzis and detection for product development
    (Informatik 2014, 2014) Chamakh, Akram; Roller, Dieter
    The main goal of this paper is to present a software solution to analyze and to detect textual based requirements in the first stage of product development. After detecting the orders and requirements, the algorithm is supposed to generate automatically the related codes used for the identical requirements. This code will be used later in a related software or machine.

    Modeling business processes with BPEL4WS
    (Modellierung 2004, 2004) Leymann, Frank; Roller, Dieter
    Business Process Execution Language for Web Services (BPEL4WS) allows defining both, business processes that make use of Web services, and business processes that externalize their functionality as Web services. This short paper introduces the basic language elements of BPEL4WS using a simple example. The concepts underlying the language are briefly explained: Establishing bilateral partnerships, correlating messages and processes, defining the order of the activities of a business process, event handling, handling exceptions via longrunning transactions, the resulting programming model, and the usage of BPEL4WS in pure B2B scenarios.

    Towards Workflow Benchmarking: Open Research Challenges
    (Datenbanksysteme für Business, Technologie und Web (BTW 2015), 2015) Pautasso, Cesare; Roller, Dieter; Leymann, Frank; Ferme, Vincenzo; Skouradaki, Marigianna
    Workflow Management Systems (WfMS) provide platforms for delivering complex service-oriented applications that need to satisfy enterprise-grade quality of service requirements such as dependability and scalability. The performance of these applications largely depends on the performance of the WfMS supporting them. Comparing the performance of different WfMSs and optimizing their configuration requires that appropriate benchmarks are made available. In this position paper we make the case for benchmarking the performance of WfMSs that are compliant with the Business Process Model and Notation 2.0 standard and explore most of the challenges that one must tackle when constructing such benchmarks.

    Web services invocation framework: A step towards virtualizing components
    (XMIDX 2003, XML Technologien für Middleware – Middleware für XML-Anwendungen, 2003) König, Dieter; Kloppmann, Matthias; Leymann, Frank; Pfau, Gerhard; Roller, Dieter
    Initially, Web services had to do with communication between executables via ubiquitous Internet protocols and technologies. But in the meantime, Web services are used as virtualization layer for any kind of executables, both within an enterprise as well as across enterprises. As a consequence, any kind of protocol and communication technology must be supported to allow users to stay in the Web service paradigm when communicating with program functions. We introduce the Web Services Invocation Framework (WSIF) which provides a flexible runtime environment for the invocation of Web services. With a client interface that is independent from the actual invocation protocol, it supports an extensible set of protocol bindings, and performs the Web service invocation in a fully dynamic or completely compiled style. We describe the major properties of the architecture of WSIF, explain its extensibility concepts and describe its client programming model.
