Models have evolved from mere pictures supporting human understanding and communication to sophisticated knowledge structures processable by machines and establish value through their processing capabilities. This entails an inevitable need for computer-understandable modeling languages and causes formalization to be a crucial part in the lifecycle of engineering a modeling method. An appropriate formalism must be a means for providing a structural definition to enable a theoretical investigation of conceptual modeling languages and a unique, unambiguous way of specifying the syntax and semantics of an arbitrary modeling language. For this purpose, it must be generic and open to capturing any domain and any functionality. This paper provides a pervasive description of the formalism METAMORPH based on logic and model theory-an approach fulfilling the requirements above for modeling method engineering. The evaluation of the formalism is presented following three streams of work: First, two evaluative case studies illustrate the applicability of METAMORPH formalism concept by concept on the modeling language PROVIS from the domain of stochastic education and the well-known Entity-Relationship language. PROVIS as well as ER comprise only a few objects and relation types but with high interconnection and expressive power and are therefore considered interesting specimens for formalization. Second, a comprehensive juxtaposition of METAMORPH to three other formalization approaches based on different foundational theories is outlined concept by concept to underpin the formalism design. Third, an empirical evaluation has been performed, assessing the usability and adequacy of the formalism within a classroom assessment. The results allow for conclusions on the completeness, intuitiveness, and complexity as well as on interdependencies with engineers' skills.

The goal of this paper is to establish the notion of "technology-specific modeling method" instantiated by a showcase example that was realized as a Design Science artifact, within the agile modeling method engineering framework, considering a particular technological context and technology-dependent purpose - the management of ETL (extract-transform-load) processes and their interoperability with an in-house ETL platform running in an organization that deals with heavy data management and orchestration tasks. With the term "technology-specific", we refer to a level of specificity that does not stem from concepts pertaining to the business sector or goals, but from technological abstractions already available in the model-driven environment where models are intended to be used. Besides reporting on the engineering details of a showcase modeling language, the paper also draws theoretical reflections on the notion of "technology-specific modeling" and what distinguishes it from the traditional domain-specific class of modeling languages.

OMiLAB is a community of practice which offers a digital ecosystem bringing together open technologies to investigate and apply conceptual modeling methods for varying purposes and domains. One of the core value propositions is a dedicated Digital Innovation environment comprising several toolkits and workspaces, designed to support Product-Service Systems (PSS) prototyping - a key ingredient for PSS lifecycle management. At the core of this environment is a notion of agile Digital Twin - a conceptual representation that can be tailored with knowledge engineering means to bridge the semantic and functional gap between a business perspective (focusing on value creation) and an engineering perspective (focusing on cyber-physical proofs-of-concept). To facilitate this bridging, the hereby proposed environment orchestrates, across three abstraction layers, methods such as Design Thinking, agile modeling method engineering and Model-driven engineering to turn Ideation into smart Product-Service Systems experiments, in a laboratory setting. The proposed environment was built following Design Science principles. It addresses the problem of historically-disconnected skills required for Digital Innovation projects and it provides a testbed for feasibility experimentation. For design-oriented, artifact building research, a higher Technology Readiness Level can thus be achieved (compared to the level that idea development methods typically attain).(c) 2022 Elsevier B.V.

The notion of "modeling method requirements" refers to a category typically neglected by RE taxonomies and frameworks - i.e., those requirements that motivate the realization of (conceptual) modeling methods and tools. They can be considered domain-specific, in the sense that all modeling methods provide a knowledge schema for some selected application domain (narrow or broad). Besides this inherent domain-specific nature, we are investigating how the characteristics of modeling methods inform the RE perspective, and how in turn RE can support the engineering of such artifacts. Thus, the work at hand aims to raise awareness about modeling method requirements in the RE community. The core contribution is the CoChaCo (Concept-Characteristic-Connector) method for the representation and management of such requirements, as well as for streamlining with subsequent engineering phases. CoChaCo is itself a modeling method - i.e., it achieves its goals through diagrammatic modeling means for which a supporting tool was prototyped and evolved. The proposal originates in required support for the initial phase of the agile modeling method engineering (AMME) methodology, which was successfully applied in developing a variety of project-specific modeling tools. From this accumulated experience, awareness of "modeling method requirements" emerged and informed the design decisions of CoChaCo.

A knowledge-driven digital nudging approach to recommender systems built on a modified Onicescu method

Product recommendations are generally understood as data-driven - however, we argue that knowledge-driven management decisions may also play a role, especially in the cold start problem, which has been tackled with various degrees of success through a number of approaches. We hereby advocate an approach that captures managerial priorities in the act of recommendation building - i.e., the proposal is to complement the traditional customer-centric view (affected by uncertainty) with a machine-readable business-centric view. For this purpose, the paper reports on an engineered method for the "digital nudging" of recommendations - it starts by capturing a manager's priorities with diagrammatic means, which are further exposed as a Knowledge Graph to a recommender built on a modified version of the Onicescu method taking into consideration a business "utility" concept to influence decision-making. The research follows the Design Science methodology, resulting in a "method" artifact that tackles the cold start with the help of a (by-design) recommendation nudging mechanism. In terms of method engineering, the proposal orchestrates its ingredients into a coherent method with the help of (a) agile modeling method engineering, to setup up a diagrammatic tool for prioritization rules, (b) the Resource Description Framework, to capture the diagrammatic rules in knowledge graph form, and (c) the Onicescu multi-criteria decision method with modifications based on Zipf's Law. The evaluation was based on surveys with potential stakeholders, for the different steps of the method. The implications are that the notion of "digital nudging" can take a knowledge-driven form, engineered as an artifact that bridges the decision-makers' priorities (captured by diagrammatic means) with the customer-facing output (recommendations), instead of relying solely on the accumulated history of transactional data. This interpretation of digital nudging may be extended towards other "digital choice e

modeling tools, as an instrument in support of the Requirements engineering (RE) process, usually focus on a particular aspect, in a domain-agnostic manner. The tutorial discusses meta-modeling as an approach to overcome such shortcomings, enabling more holistic and specific semantic coverage of requirements models. The meta-modeling platform ADOxx is introduced as an experimentation environment for researchers and practitioners to realize their individual modeling languages and functionality in support of RE. Specific emphasis is given to the practical nature of the tutorial: participants are encouraged to build their individual modeling tool in a hands-on setting and experiment with the capabilities of ADOxx to implement meta-models and model processing mechanisms, to specialize them or to integrate available assets provided by the *** community.

An Open Platform for modeling method Conceptualization: The OMiLAB Digital Ecosystem

COMMUNICATIONS OF THE ASSOCIATION FOR INFORMATION SYSTEMS 2019年第1期44卷 673-697页

This paper motivates, describes, demonstrates in use, and evaluates the Open Models Laboratory (OMiLAB)-an open digital ecosystem designed to help one conceptualize and operationalize conceptual modeling methods. The OMiLAB ecosystem, which a generalized understanding of "model value" motivates, targets research and education stakeholders who fulfill various roles in a modeling method's lifecycle. While we have many reports on novel modeling methods and tools for various domains, we lack knowledge on conceptualizing such methods via a full-fledged dedicated open ecosystem and a methodology that facilitates entry points for novices and an open innovation space for experienced stakeholders. This gap continues due to the lack of an open process and platform for 1) conducting research in the field of modeling method design, 2) developing agile modeling tools and model-driven digital products, and 3) experimenting with and disseminating such methods and related prototypes. OMiLAB incorporates principles, practices, procedures, tools, and services required to address the issues above since it focuses on being the operational deployment for a conceptualization and operationalization process built on several pillars: 1) a granularly defined "modeling method" concept whose building blocks one can customize for the domain of choice, 2) an "agile modeling method engineering" framework that helps one quickly prototype modeling tools, 3) a model-aware "digital product design lab", and 4) dissemination channels for reaching a global community. In this paper, we demonstrate and evaluate the OMiLAB in research with two selected application cases for domain- and case-specific requirements. Besides these exemplary cases, OMiLAB has proven to effectively satisfy requirements that almost 50 modeling methods raise and, thus, to support researchers in designing novel modeling methods, developing tools, and disseminating outcomes. We also measured OMiLAB's educational impact.

A Semantic Approach to Deploying Product-Service Systems

引用

INTERNATIONAL JOURNAL OF INFORMATION SYSTEM modeling AND DESIGN 2017年第1期8卷 24-42页

Conceptual modeling is commonly employed for two classes of goals: (1) as input for run-time functionality (e.g., code generation) and (2) as support for design-time analysis (e.g., in business process management). An inherent trade-off manifests between such goals, as different levels of abstraction and semantic detail is needed. This has led to a multitude of modeling languages that are conceptually redundant (i.e., they share significant parts of their metamodels) and a dilemma of selecting the most adequate language for each goal. This article advocates the substitution of the selection dilemma with an approach where the modeling method is agilely tailored for the semantic variability required to cover both run-time and design-time concerns. The semantic space enabled by such a method is exposed to model-driven systems as RDF knowledge graphs, whereas the method evolution is managed with the agile modeling method engineering framework. The argument is grounded in the application area of Product-Service Systems, illustrated by a project-based modeling method.
