Network-based – Quality Function Deployment (NB-QFD): The combination of traditional QFD with network science approach and techniques

Hypergraph and network flow-based quality function deployment

“…The diverse application area of the method has initialized the extension of QFD with new approaches. The extensively improved QFD methods seek to overcome the drawbacks such as the importance value is not clearly stated, negative numbers are not accepted in the analysis, the construction and evaluation can be time-consuming, the prioritization is mainly qualitative and subjective, it is hard to categorize parameters, provides single-layer evaluation [11] and it cannot be used effectively when multi-criteria are required [12] . Furthermore, the general evaluation of QFD considers the correlation matrix of development parameters, and it serves as additional information for the development team.…”

“…A zero-one goal programming methodology has been introduced that also includes the importance levels of development parameters (correlation matrix), which are derived using the “ANP, cost budget, extendibility level, and manufacturability level goals” to determine the development parameters to be considered in designing the product [58] . The network-based approach of QFD regarding CNC machine tool development is proposed and reveals the potential of utilizing the correlation network [11] . The potential in analyzing cascade of houses through networks has been highlighted [56] , however the correlation matrix is missing from the computation.…”

Research on Customer Requirement Prioritization of Engineering Products Based on Group Multi-Granularity Linguistic Information

“…Step 3: The evaluation vector of the importance of each customer requirement was listed according to the importance uniformity matrix, as shown in Table 1. According to Equations ( 3) and ( 4), the positive ideal points and negative ideal points of each customer requirements importance evaluation vector were listed as U + = (BS 4 3 , BS 4 3 , BS 4 3 , BS 4 3 , BS 4 4/3 , BS 4 3 ), V -= (BS 4 0 , BS 4 -1 , BS 4 0 , BS 4 1/3 , BS 4 0 , BS 4 -1 ).…”

“…Analytic network process (AHP) or analytic hierarchy process (ANP) are used to determine the priority of customer requirements. The method requires the evaluator to make pair-based comparisons of demand to get an accurate number, which is difficult for the decision-makers [4] . Considering the assessment of environmental uncertainty, fuzzy set theory has been adopted to analyze the priority of customer requirements.…”

Evaluation of PC-FMEA Using Network Analysis

“…In the network, αij denotes the connection of node i to node j and each link (i, j) has a weight wij. The weighted in-degree w1Dj is calculated as follows [9]:…”
