“…However, it is common that criteria are defined only shortly before the decision situation, which can lead to criteria not corresponding to the requirements, nevertheless because of the manual definition. Horber et al (2020) therefore present an approach that allows the (semi-) automated derivation of requirements into evaluation criteria already during the requirements specification (see Figure 1). This approach is therefore understood in this paper as a requirements-oriented decision making.…”

“…At the beginning and during development, different requirements are defined, which are (semi-) automated derived into evaluation criteria according to the approach presented by Horber et al (2020). This approach is therefore used as a starting point for the developed approach to first set up the relational model for requirements and then use the knowledge from the (semi-)automated derivation in decision making.…”

The development of complex technical systems is characterized by a large number of system elements as well as their interactions. With regard to requirements management, many requirements have to be considered, which can have different relations to each other. If these requirements are used as basis for criteria in the decision making process, these relations must also be considered in the multi-criteria evaluation of product alternatives. Therefore, a computer-aided approach is presented in this paper, which allows the systematic modeling of requirement interactions focusing on multi-criteria decision making. For this purpose, basic relation types are identified, which are used to model submatrices in order to derive the Requirement Relation Matrix (RRM). Matrix-based as well as graph-based visualization methods are used for the RRM in order to improve the alternatives with the knowledge about the relational linkage. In addition, the effects of changes in requirements can be transferred to the decision making process. The approach is exemplarily applied to the extension of a test laboratory by a test bench.

“…The classification uses the classes necessity (wish/demand), aspect (qualitative/quantitative) and condition (hurdle/optimization) defined in preliminary work (Horber et al, 2019). Since this classification focuses on the automated derivation of evaluation criteria (Horber et al, 2020), it is reasonable for the intended robustness evaluation.…”

The success of complex product development projects strongly depends on the clear definition of target factors that allow a reliable statement about the fulfilment of the product requirements. In the context of tolerancing and robust design, Key Characteristics (KCs) have been established for this purpose and form the basis for all downstream activities. In order to integrate the activities related to the KC definition into product development as early as possible, the often vaguely formulated requirements must be translated into quantifiable KCs. However, this is primarily a manual process, so the results strongly depend on the experience of the design engineer.In order to overcome this problem, a novel computer-aided approach is presented, which automatically derives associated functions and KCs already during the definition of product requirements. The approach uses natural language processing and formalized design knowledge to extract and provide implicit information from the requirements. This leads to a clear definition of the requirements and KCs and thus creates a founded basis for robustness evaluation at the beginning of the concept design stage. The approach is exemplarily applied to a window lifter.
