Model-Based Assistance and Information Services (MBAIS)

MBAIS - Model-Based Assistance and Information Services Informatics as a research discipline must constantly face new challenges such as heterogeneous information sources, growing amounts of structural and behavioural data, and broad range of possible end-users. Thus, the need for (a) assistive and (b) information services and systems grows. We meet these challenges by using models and model-based software engineering as foundation to develop data-centric information systems.

Model-Based Software Engineering. Generating software is an important capability for a tooling infrastructure that successfully assists modeling in the development process (see "Agile Model Based Software Engineering"). As every application domain has its own terms, relations, structure and behaviour, there is a need for developing different Domain Specific Languages (DSLs) for each domain and/or purpose. The automatic combination of models from a variety of DSLs ensures consistency (e.g. for front- and backend).

Data-Centric Information Systems and Services. Systems and services for the representation of big amounts of data such as web-information portals are commonly used and their representation and system architecture highly depends on the domain in focus. Using generative methods accelerates the development process (see "Generative Software Engineering") and decreases development time, as changes of the models are easily passed on to the source code. We are demonstrating the practical application of this approach , e.g., in the MaCoCo and InviDas project using the generator framework MontiGem.

Human-Centered Assistance Systems and Services. A step further from informing users is to provide support to them. Supportive or also called assistive systems and services support human processes both, at work and in private life. It is again an emerging research field regarding the digital transformation of numerous application areas. Such assistance services are commonly embedded in a larger system architecture combining devices and resources, receiving data from sensors and communicate with functions and services. Model-based approaches improve the communication capabilities of these components and ensure consistency. Formal verification methods can be applied to a safety-critical subset of these components and their communication. Moreover, model-based approaches can be used to support privacy-by-design and eases human-centered development approaches.

Application Domains. Assistance and Information Services are relevant in a variety of domains. Each of them with its' own specifications, ideas and legal restrictions. Thus, it is important to strongly involve domain experts into the development process of such systems and services. This involvement can be supported by using MBSE: Prototypes and functionalities can be developed fast, changes can be easily handled, end users can provide feedback in an earlier development stage and feature requests can be implemented faster.

The group members already have experiences in the following domains:

  • Ambient Assisted Living
  • Controlling and Finances
  • Energy
  • Health
  • Internet of Production (IoP)
  • Internet of Things (IoT)
  • Industry 4.0
  • Smart Homes

Research Questions

  • What are further evolvement steps in theoretical foundations of model based code generation? How is it possible to combine different languages?
  • What are the domain specific modelling languages and methods required for the creation of web information systems? How are these engineered, integrated, and reused? How does this translate to modeling tools, analysis, transformations, and code generators?
  • What are the domain specific modelling languages and methods required for assistance services? What are the architectural components and how are they interrelated?
  • How is it possible to ensure privacy-by-design of information and assistive systems in combination by using model-based software engineering? What aspects are relevant to be represented in privacy information portals to support privacy preservation for end users?
