    Safety-oriented Process Line Engineering via Seamless Integration between EPF Composer and BVR Tool: Variability Management in Process Lines2018In: SPLC '18 Proceeedings of the 22nd International Systems and Software Product Line Conference - Volume 2, 2018, p. 23-28Conference paper (Refereed)
    Abstract [en]

    The integration between process engineering and variability management is required for tailoring of safety-oriented processes with variabilities to individual projects in a similar manner to the product lines. Previous studies have not adequately established the Safety-oriented Process Lines (SoPLs). This paper focuses on the seamless integration between Eclipse Process Framework (EPF) Composer and Base Variability Resolution (BVR) Tool. The former supports the major parts of the OMG’s Software & Systems Process Engineering Metamodel (SPEM) Version 2.0, while the latter is a simplification and enhancement of the OMG’s revised submission of Common Variability Language (CVL). The proposed integration is implemented as Eclipse plugin. It provides support for importing backend folders and files within the method library of EPF Composer, resolving problems with the files for variability management with the BVR Tool, and exporting back the resolved process models to the EPF Composer. The applicability of the implemented plugin is demonstrated by engineering an ECSS-E-ST-40C compliant SoPL for the space projects and applications.

    Towards variant management and change impact analysis in safety-oriented process-product lines2019In: Proceedings of the ACM Symposium on Applied Computing, Association for Computing Machinery , 2019, p. 2372-2375Conference paper (Refereed)
    Abstract [en]

    In safety-critical (software) systems, safety management embraces both processes and products, which due to e.g., product's upgrade, tend to be tailored, giving rise to safety-oriented product lines and corresponding safety-oriented process lines. To tailor these lines systematically, their inter-dependencies would have been taken into consideration. To date, however, no satisfying implemented solution is available on the shelf. Accordingly, this paper focuses on the co-engineering of process and product lines. At first, the process and product lines need to be established for which the integration between Eclipse Process Framework (EPF) Composer, Composition with Guarantees for High-integrity Embedded Software Components Assembly (CHESS) Tool and Base Variability Resolution (BVR) Tool is achieved; they are process engineering, product design and variant management solutions, respectively. After that, the process and product lines are integrated. This is done for cross-dimension variant management and change impact analysis. The applicability of the integrated lines is illustrated for the attitude and orbit control subsystem.

    System of Systems Hazard Analysis Using HAZOP and FTA for Advanced Quarry Production2019In: 2019 4th International Conference on System Reliability and Safety, ICSRS 2019, Institute of Electrical and Electronics Engineers Inc. , 2019, p. 394-401Conference paper (Refereed)
    Abstract [en]

    The advanced production systems are composed of separate and distinct systems that operate in both isolation and conjunction, and therefore forms the System-of-Systems (SoS). However, a lot of production systems are classified as safety-critical, for example, due to the interactions between machines and involved materials. From the safety perspective, besides the behaviour of an individual system in SoS, the emergent behaviour of systems that comes from their individual actions and interactions must be considered. An unplanned event or sequence of events in safety-critical production systems may results in human injury or death, damage to machines or the environment. This paper focuses on the construction equipment domain, particularly the quarry site, which solely produce dimension stone and/or gravel products. The principal contribution of this paper is SoS hazard identification and mitigation/elimination for the electric quarry site for which the combination of guide words based collaborative method Hazard and Operability (HAZOP) and Fault Tree Analysis (FTA) are used. The published studies on HAZOP and FTA techniques have not considered the emergent behaviours of different machines. The applicability of particular techniques is demonstrated for individual and emergent behaviours of machines used in the quarry operations, such as autonomous hauler, wheel loader, excavator and crusher.
