Design Alternatives

Product evaluation practices spread throughout from initial creative stages to final products before communicating them to the market. They emphasize on assessing design alternatives against specified criteria, which can help promote design process, ensure design quality, and diminish design risk before making a decision. However, how to identify and improve the reliability of product evaluation opinions toward design alternatives has an important role in adding additional insurance and reducing uncertainty to successful product design. Aiming at this issue, this study employs a consensus model by integrating network analysis and analytic hierarchy process (AHP) method. The consensus model is constructed to measure the consistency of evaluators’ preferences and determine the rounds of evaluation. Complex network theory is integrated into the product evaluation process for network analysis of evaluators’ opinions, which can help determine evaluators’ weights in each evaluation round dynamically by changing the network topology. To obtain the weight of product evaluation indices, the AHP method is applied to avoid subjectivity given by evaluators. The process of the proposed method is presented, and the details are illustrated using a product evaluation example. The case study demonstrates that the proposed method is promising for improving the consensus level of evaluators’ opinions, reducing the influence of subjectivity, and finally improving the quality of design decision-making.

Qualitative Index

For a more scientifically evaluate of home appliance product design, on basis of determining the evaluation index, Fuzzy AHP (Fuzzy-Analytic Hierarchy Process) comprehensive evaluation method is used to converse qualitative index to quantitative index, establish a home appliance product design evaluation model, overcome subjectivity and arbitrariness of evaluation, and scientifically realize the evaluation of home appliance product design. Research shows that the evaluation system can easily actualize the evaluation of home appliance product design conveniently and effectively.

Node Importance

The identification and evaluation of important parts play an important role in effective production arrangement and shortening the product development in the product design stage. In this paper, a complex product node importance evaluation method based on multilayer network is proposed to identify and evaluate importance parts faster. First, a complex product design expression network based on “function behavior structure (FBS)” multilayer complex network is established. Second, the evaluation index system of important design parts for complex products based on multilayer network is constructed. Third, a three-parameter grey relational model based on the fuzzy analytic hierarchy process and the Gini coefficient method is proposed. Finally, this method is available and feasible through taking the large permanent magnet synchronous centrifugal unit as an example.

Intuitive Interface

In this paper, an intuitive interface of synthesized industrial design and engineering analysis of multi-material product is proposed. In a product design cycle, designers not only need to determine the geometry of a design, but also need to verify the design functions. Besides the concerns of function and geometry, other requirements like ergonomics, aesthetics, and types of visible surfaces also need to be considered. All these concerns are considered in this research through an investigation into multi-material product design. Multi-material product manufacturing processes allow designers to select different materials for different portions of objects in order to improve material-function compatibility for the overall object. Based on a haptic shape modeling system, a permutation method for multi-material product design is developed. A volumetric FEM-based function evaluation method is adopted for multi-material product analysis with the assumption of small displacements. The design and analysis are conducted on the same platform which is enhanced with a haptic device that can provide an intuitive correlation between the applied force and incurred displacement. The methodology is presented through a case study: the design of a toothbrush.
