    Bridging requirements engineering and business process management
    (Software Engineering 2009 - Workshopband, 2009) Decreus, Ken; Kharbili, M. El; Poels, Geert; Pulvermueller, Elke
    Requirement elicitation is one of the earliest phases of a requirement engineering lifecycle. However, even though years of research have gone into seeking machine support for requirements engineering, the methods used are still highly manual and the vision of automatic transfer of business analysis requirements into IT systems supporting the business is still far from reach. On the other hand, incepting knowledge for creating AS-IS business processes in enterprise models has been recognized as a hard problem. In the context of a process centric organization, we propose an approach to create AS-IS business process models by automatically transferring requirements to the business process layer. Our aim is to enable carrying business requirements, goals and policies from an inception layer to the operational business process management layer. We place our research in the context of a semantic business process management platform (SUPER) as the support to exploit the output of our research. This paper grounds this research work and proposes a research design for requirement elicitation for producing early-phase business process models that are nearer to the business analysis layer.

    A Capability Oriented Management Approach for Business Integration
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Pulvermueller, Elke; Ludwig, André; Belter, Roman; Zyskowski, Dominik; Heindl, Ulrich; Nguyen, Xuan Thang
    Service oriented architecture (SOA) has emerged as a popular software paradigm for integrating distributed applications. Services are generally regarded as interoperable building blocks for constructing, integrating, and merging applications. However, existing SOA based solutions often focus on solving technical integration problems while neglecting business-level capabilities which are most important for organizations. In this paper, we introduce the notion of capabilities as an important concept for business management. We identify major shortcomings of the existing service based solutions and outline a novel approach for capability oriented configu- ration and management that can react to the dynamically changing nature of business integration environments.

    Early Model-Driven Timing Validation of Embedded Software Systems Developed Using Matlab/Simulink
    (Softwaretechnik-Trends Band 38, Heft 1, 2018) Iyenghar, Padma; Pulvermueller, Elke
    This paper presents a model-driven workflow for specification of timing constraints in Matlab/Simulink (ML/SL), their extraction and synthesis of a timing analysis model and its subsequent validation in a specialized timing validation tool (e.g. SymTA/S). We present a light-weight interfacing tool framework, adhering to the proposed workflow, and evaluate it in a real-life automotive engine model example. A main benefit of this work is the feedback at early d design stage, about the performance characteristics (e.g. load, schedulability) of the system.

    Model-Based Debugging of Embedded Software Systems
    (Softwaretechnik-Trends Band 31, Heft 3, 2011) Iyenghar, Padma; Pulvermueller, Elke; Westerkamp, Clemens; Uelschen, Michael; Wuebbelmann, Juergen
    Model Driven Development (MDD) has been slowly superseding traditional ways of developing embedded software in the recent decade. In line with the MDD, debugging Real-Time Embedded Software Systems (RTESS) and visualizing their behavior using models such as UML diagrams is becoming a reality. However, the existing MDD based debugging tools for RTESS are not applicable (require significant source code instrumentation, sophisticated debug interfaces, etc) for memorysize constrained RTESS. To address this, we discuss a modelbased debugging methodology for RTESS which aims at overcoming the aforementioned limitations. Using our approach, the target behavior can be visualized in real-time using UML sequence and timing diagrams. We illustrate our approach with a prototype and examples. Performance metrics such as the target monitor size and the instrumentation overhead are discussed.
