Comparative Concept Study and Evaluation for New Broadband Noise Absorbing Acoustic Liner Concepts for Civil Aviation

“… Acoustics,  System Safety and Integration, and  Structure and Material have been introduced to not falsify the assessment results by subject-specific exclusion criteria. The ranked space method according to Breiing and Knosala [24] has been selected for weighting the evaluation criteria to ensure an objective and knowledge-based rating. The rating has been carried out by a weighted point rating, which has been conducted by the project partners with different fields of expertise.…”

“…Different weighting methods such as  the hierarchical weighting [06],  weighting by target preference matrix [07], [09],  the weighting by means of influence matrix [09] and  the weighting by ranked space method [24] can be used.…”

“…The final weighting is carried out by means of ranked space method and separately for each individual MEC to increase the objectivity. When using the ranking method of Breiing and Knosala [24] for the weighting, all evaluation criteria are compared against each other in a matrix. If the row criterion is more important than the column criterion, the corresponding cell is assigned the value 2.…”

Procedure Model for Structured Relational Modeling of Requirements to Support Requirements-Oriented Decision Making

“…According to Graeßler et al (2020) and Dermeval et al (2016), ontology-based approaches are a promising way to support the identification of interactions, as presented exemplary by Soomro et al (2014). However, dependencies and interactions do not only occur in the area of requirements management, but also in the area of decision making, although in multi-criteria evaluation a condition is that criteria are independent of each other (Breiing and Knosala, 1997). Regarding this restriction, the Analytic Hierarchy Process (AHP) was developed, which was then extended to the Analytic Network Process (ANP), which consider the interactions occurring in practice (Saaty, 2004;Sipahi and Timor, 2010).…”

“…They describe the activities of discovery, management, and disposition of critical relationships (Robinson et al, 2003). Breiing and Knosala (1997) present a very generic model from the research field of decision making, which contains only the most important relations necessary for multi-criteria evaluation. A summary of the analysis is shown in Table 1.…”
