“…Tian et al [29] developed an improved ANP-TODIM approach to resolve MCDM problems where the criterion weights are fully unknown, and it has been successfully applied in optimal tourism attraction recommendation. Mistarihi [30] established a decision-support framework for wheelchair design, in which the fuzzy-ANP approach is applied to determine the importance of engineering characteristics. Although the classic or improved ANP method has been applied in many fields and gained high recognition, few studies have captured both the symmetrical interdependence between criteria and the reliability of evaluation information simultaneously.…”

Under the double pressure of global energy consumption and climate change, nuclear power has become a low-carbon alternative energy source that could transform the energy structure of the globe. In the nuclear power industry, selecting suitable suppliers plays a significant role in improving the overall performance of nuclear power projects. Along with this symmetrical impact, this paper aims to develop a multistage decision-support framework to determine the optimal nuclear power equipment supplier, which is constructed in the context of Z-number information. Concretely, the Analytic Network Process (ANP) and Tomada de Decisão Iterativa Multicritério (TODIM) are extended by Z-numbers symmetrically—namely, Z-ANP and Z-TODIM. Z-ANP is first applied to analyze the symmetrical interdependence of criteria, so as to accurately determine the criterion weights. Further, the ranking of alternatives is obtained by Z-TODIM, which sufficiently considers the risk preference and psychological states of decision-makers. Finally, a practical case of nuclear-grade cable procurement in the Karachi 2-3 international nuclear power project is performed to illustrate the practicality of the proposed method, and its robustness and superiority are proven by comparing it with current representative approaches.

“…Validity Test is to determine whether the data obtained is valid or not, starting from the initial data to the last one, a data is said to be valid if r count is greater than r table. Relativity test is a test that is conducted to determine the reliability of the data that we can or get.Ergonomic Function Deployment(EFD) is a development of Quality Function Deployment (QFD) by adding a new relationship between consumer desires and ergonomic aspects of the product (Nurdin et al, 2018;Fargnoli et al, 2018;Mamagahani et al, 2019;Mistarihi et al ., 2020). This relationship will complete the House of Quality matrix form which also translates intodesirable ergonomic aspects.…”

The appointment of catering dishes at Dian Rasa Catering is currently still done manually by hand. Slouching work posture when lifting plates increases the risk of muscle and spinal injuries in workers. One way that can be done is to design ergonomic plate lifters. The design of an ergonomic trolley uses the Ergonomic Function Deployment (EFD) method. The attributes used are based on ergonomic aspects, which are effective, comfortable, safe, healthy, and efficient. Based on the attributes used, it can be seen the desires and needs of consumers for products which are then integrated with the technical characteristics of the tool. Obtained the results of the design of a catering plate lifter in the form of 3 plate racks with a radius of 21 cm that can accommodate 20 plates and trolleys with a height of 125 cm and the size of the trolley handle that can be adjusted according to the smallest body size (118 cm), on average (125 cm)) and maximum (132 cm). The results of the experimental an ergonomic trolley help the employee to lift the plate, improve time efficiency and reduce the risk of muscle and bone injury to the catering employee. After the use of plate lifting tools catering harvest workers labor posture scores using the OWAS method dropped to 1.

“…This misconnection has avoided also the identification of how each one of the design or production factors has contributed to fulfilling each customer need. Therefore, QFD aims to provide a methodology that takes costumers' requirements as the main driver in the design process [15,16,19].…”

“…On the other hand, matrix C (refer to Equation (6)) denotes an n-dimensional column vector, representing the total of the weighted values for the important intensity of criteria. Then, CR (Consistency Ratio) (refer to Equation (7)) is computed using the RI (Random Consistency Index, depending on the size of the problem) [19]. If the CR < 0.10, the matrix is considered consistent, and the derived weights are then reliable for supporting decision-making.…”

Smart Product Design Process through the Implementation of a Fuzzy Kano-AHP-DEMATEL-QFD Approach

et al. 2020

View full text Add to dashboard Cite

Product design has become a critical process for the healthcare technology industry, given the ever-changing demands, vague customer requirements, and interrelations among design criteria. This paper proposed a novel integration of fuzzy Kano, Analytic Hierarchy Process (AHP), Decision Making Trial and Evaluation Laboratory (DEMATEL), and Quality Function Deployment (QFD) to translate customer needs into product characteristics and prioritize design alternatives considering interdependence and vagueness. First, the customer requirements were established. Second, the fuzzy KANO was applied to calculate the impact of each requirement, often vague, on customer satisfaction. Third, design alternatives were defined, while the requirements’ weights were calculated using AHP. DEMATEL was later implemented for evaluating the interdependence among alternatives. Finally, QFD was employed to select the best design. A hip replacement surgery aid device for elderly people was used for validation. In this case, collateral issues were the most important requirement, while code change was the best-ranked design.
