Astract: The perception of the value and propriety of modern engineered systems is changing. In addition to their functional and extra-functional properties, nowadays’ systems are also evaluated by their sustainability properties. The next generation of systems will be characterized by an overall elevated sustainability—including their post-life, driven by efficient value retention mechanisms. Current systems engineering practices fall short of supporting these ambitions and need to be revised appropriately. In this paper, we introduce the concept of circular systems engineering, a novel paradigm for systems sustainability, and define two principles to successfully implement it: end-to-end sustainability and bipartite sustainability. We outline typical organizational evolution patterns that lead to the implementation and adoption of circularity principles, and outline key challenges and research opportunities.

Astract: Business Process Management (BPM) takes care of the business process (BP) lifecycle using different technologies in organizations to provide value-added services or products for end-users. Although today’s fast-changing business world poses vast variants of business processes (BPs) alongside uncertainty. This situation requires an agile BPM to manage, maintain, and execute different variants of a BP as well as deal with uncertainties and changes. One of the emphasises of agile BPM is involving stakeholders in the BP lifecycle, which requires a standard approach for all stakeholders to have quick and efficient access to the BP lifecycle to prevent problems like cultural resistance. In order to reach a standard approach, social BPM is an emerging concept that can help the easy and efficient involvement of stakeholders in the BP lifecycle. By inspiring form social BPM, this paper propose a new social media-based BPM platform to deal with different varieties of BP and uncertainties by integrating stakeholders in the BP lifecycle. While the platform eases communication, information exchange, and decision-making among stakeholders; it also eliminates the exchange between design-time and run-time while a change occurs by merging design-time and run-time.

Keywords: Agile BPM, Agility, AI agent, Business Process Management, Social BPM
Astract: Business Process Management (BPM) faces increasing societal and business challenges. Societal issues include effectively managing unexpected changes and ensuring employee engagement during process modifications. The former category involves the limitations of technology when introducing process changes while Agile BPM and Social BPM concepts have been explored in previous studies to tackle the latter. These investigations have resulted in the development of a Social-Media (SM) based BPM platform and an agility framework. The SM platform draws inspiration from popular social media platforms such as Twitter and Instagram. Its primary objective is to merge the design-time and run-time phases of the business process (BP) lifecycle as well as to actively engage stakeholders in the dynamic design and implementation of BPs. By simplifying the response to potential changes and maintaining stakeholder involvement throughout the process, the platform addresses the aforementioned challenges. This article establishes a correlation between SM platform concepts and BPM concepts, emphasizing how they facilitate the concurrent design and execution of BPs. Furthermore, the article demonstrates the application of the SM platform in implementing the agility framework through a use case analysis involving a scientific paper submission process. To overcome the current emphasis on stakeholder involvement and human capabilities in applying the platform, we finally explore the possibilities of employing AI agents as automated assistants.

Keywords: Artificial intelligence, Cloud platform, Conceptual modeling, Knowledge graph, Model transformation, Model-driven engineering
Astract: Semantic processing of conceptual models is a focus of research for several years, bridging the disciplines of knowledge-based systems, conceptual modeling, and model-driven software engineering. With Knowledge Graphs, this research area gained momentum. In this paper, we introduce CM2KGcloud, a generic and extensible Web-based platform for transforming conceptual models into Knowledge Graphs. The platform can work on models created by state-of-the-art metamodeling platforms (e.g., EMF, Papyrus, ADOxx) and transforms models created with them into standardized Knowledge Graph representations like GraphML, RDF, and OWL. CM2KGcloud can be used as a service and can be integrated into software systems by its exposed API.

Keywords: conceptual modelling, Docker-compose, feature modelling, machine learning, microservices, OMSAC, ontology population, OpenAPI
Astract: Applying the Ontology of Microservices Architecture Concepts (OMSAC) as a modelling language calls users to have expertise in ontology engineering. However, ontology practice remains restricted to a limited pool of practitioners, leading to a barrier to widely adopting such a modelling approach. Here, we present x2OMSAC, an ontology population framework that enhances the modelling of microservices architectures using OMSAC. We instantiate our framework by FOD2OMSAC, which limits modellers’ manual tasks to data selection, cleaning, and validation of created models, thereby eliminating the need for ontology expertise and, consequently, expanding the potential of OMSAC adopters for modelling microservices architectures.
