Knowledge-based IoT Design

Short Description:

An IoT is created through the networked interaction of thousands of embedded “things” whose reuse must be organized from product databases. To do this, the application functions and network interfaces (at the application layer) of these “things” must be interoperable, which can only be achieved through knowledge-based product discovery and association (e.g., through automatic IoT design). The design platform demonstrated for this purpose ( exemplifies the domain of smart building, as it has already pioneered large IoT networks and developed the necessary semantic industry standards. On the basis of a standardized exchange format (IFC –,, an ecosystem of cooperative tools for requirements gathering, design, cost calculation, simulation, tendering and awarding, testing and commissioning as well as for operation and maintenance is being developed there.

Target Group(s):

    • manufacturer of IoT products
    • system integrators
    • supplier of software tools for requirement analysis, component selection, composition and project engineering, CAD for individual domains (construction, mechanical Engineering, …)

Partner from Research, Industry:

Most partners in the tool network (ecosystem) come from other federal states. For the special part “IoT-Design”, however, the Dresden area is a leader and has a good chance of becoming the sponsor of this design platform (for example under the roof of Silicon Saxony).

Value Proposition:

Pain Killers:
    • Customers (planners, system integrators) do not know all design patterns and their possible combinations for solution concepts → bundling branch knowledge in product lines (semantic standards)
    • Customers (system integrators) have problems to search through thousands of embedded products and their interfaces or millions of possible compositions for complete systems → automatic product search and combination (draft)
Gain Creators:

A. → product line generator for semantic standards of a domain
B. → product search, combination and interoperability testing through an optimization algorithm


Teaser trail (0,5 – 1 day), also possible as a module together with other design platforms for large networked systems, IoT product databases, semantic industry standards


In this teaser trail, the automatic system design for the domain of the room automation (Smart Building, Smart Home) is demonstrated, since the “standards of the next generation” already exist here. These standards enable an exact and formal (machine-readable) description for all components in the product database (Fig. 1) as well as a specification of the task by the customer or planner (Fig. 2).

The automatic system design will be presented to the visitors by means of a practical example. A knowledge-based requirement tool is available for request collection. For each room type you can easily select the desired functions, which are sorted by craft.

After the task has been formulated, the algorithm automatically generates several complete system designs, i. a list of all used devices with their functions, their bindings and the basic parameterization. The planners or integrators therefore no longer have to consider millions of possible combinations because the algorithm has already recognized them as inappropriate and eliminated them. So planners and integrators save a lot of routine work and only have to obtain and analyze the manuals (function and interface descriptions) of the few products that are included in the promising combinations. Their correct, interoperable interconnection and graphic representation (Figure 2) is also created automatically.
In order to integrate the result of the automatic design into many existing CAD tools as a supplement, it was not conventionally implemented as a “tool” but as a web service that can be called up from any existing tool.

In the laboratory of the chair for technical information systems of the TU Dresden the generating of complete system designs will be shown. Afterwards demonstrators for smart building and smart home can be visited, which illustrate the design results. The demonstrators show the networking of different functions of a smart home, e.g. for lighting, heating control, shading and security.
A visit as part of the roadshow serves primarily to introduce and deepen detailed issues with new stakeholders. For preparation / follow-up can be used.

Current Projects:


The aim of the “ServiceFlow” project is the development of a web-based tool and service chain from customer integration (consulting) to design, installation, continuous operation and maintenance of room automation systems.


The TOPAs project is developing an open, cloud-based platform of analytical tools to minimize the gap between predicted and actual energy use in buildings.

Opportunities for Projects and Funding Instruments:

It is possible to use funding instruments from Saxony, such as SAB, ESF, NFG.
