Shorter product life cycles and high product variance nowadays require efficient engineering of products and production systems. Hereby a further challenge is that costs over the entire life cycle of the product and production system are defined early in the process. Existing approaches in literature and practice such as simultaneous engineering an...
Article
Engineering change management is a key part in the development of products that requires a lot of resources and time. A key problem is the lack of a shared ontology to describe engineering changes. This creates problems, additional effort and hinders the digitalisation of the engineering change management. This is especially true for the developmen...
Conference Paper
In product development, different artifacts, pieces of information, and documents are used at different phases in the development process. In early phases, for example, the Product Profile (PP) is often used. It contains general information about the needs of different stakeholders. In advanced phases, the artifact Development Order (DO) is used. T...

During product engineering, engineers draw on existing knowledge as a basis. This knowledge is applied in design processes either by adopting elements, alternating some attributes, or changing the solution principles. While concepts for design reuse exist, the proactive design of a suitable knowledge base is still a challenge. In this paper, we sho...

Visual representations are essential to design. Data-rich representations such as systems visualisations are gaining prominence in engineering practice. However, as such visualisations are often developed ad-hoc, we propose more systematically to link visual tasks with design-specific tasks for which the visualisations are used. Whereas research on...

In 2019, Dyson had to cancel its ambitious electric car project after having already 500 Million pounds spent. This example shows how difficult it is to assess the consequences of decisions on development targets as cost, risk, and innovation potential. Knowledge about references, variation types and their impact on development targets can help to...

Full-text available
In product development practice, it appears that engineering activities very often focus on the variation of the physical embodiment, as this is where the greatest and most obvious implications for the product seem to be perceived. Nevertheless, an empirical study revealed that variation in physical embodiment affects many other dimensions of a pro...

Many activities in the new product development requires the decision making to find the final solution from multiple alternatives and make an evaluation. Even methods to support decision maker are available, the decision can go to the wrong direction because of heuristics. “Decoy effect” is a heuristic that appears in a comparison when 2 of 3 alter...
Article
Full-text available
Heuristic decisions are automatically made during the whole product development processes to find solutions, when information and time are limited. Heuristic decisions are a simple process and give a fast response. However, they can lead to decision-making errors because of heuristic traps such as social bias and representativeness. Thus, it is imp...

As any other human being development engineers preferably act based on experience. Hence it is comprehensible that even for a product that initially appears revolutionary usually one or more references can be found. This enhances, for example, the comparability or the availability of a products subsystems so that they are more easily to deal with....
Article
Full-text available
The model of PGE – Product Generation Engineering describes the development of new technical products as follows: subsystems from one or more existing technical systems are the basis and starting point for every development. This is referred to as the “reference system”. It determines the structure and subsystems of a new product or serves as a bas...

The academic education of engineering students aims at qualifying for engineering practice. Hence courses in mechanical and mechatronic design in the early stage of engineering education include often project works, where the students themselves design technical systems. The task description usually includes a first system structure, functional and...
Conference Paper
Products are developed in teams and based on knowledge gained in previous development projects. This makes knowledge transfer a key factor for the success of product development. In addition is the development time a crucial factor. Increasing the speed of knowledge transfer is hence of great importance for product development. The SECI model descr...
