A Supernetwork-Based Model for Design Processes of Complex Mechanical Products

Abstract

Abstract:Complex mechanical products are a priority area of advanced manufacturing strategy in the USA and Europe. Excellent models for design processes of complex mechanical products are essential for managers or designers to manage design processes and further improve design efficiency. Multiple elements and complicated relationships between elements in the design processes of complex mechanical products cause difficulties in systematically and quantitatively expressing the design processes. Therefore, we put forth a supernetwork-based model for designing complex mechanical products. First, we identified the key elements in the design processes of complex mechanical products. Next, based on this we analyzed sub-elements of the key elements and relationships between sub-elements. Then we built sub-networks with sub-elements as nodes and their relationships as edges and the supernetwork model for design processes of complex mechanical products based on the sub-networks and their relationships. Meanwhile, we also present a method for combining linguistic variables with the corresponding triangular fuzzy numbers, and a max/min synthesis method to accurately compute the edge weights. Finally, we suggest the practical applications of the proposed model and give a comparison of the proposed model and existing ones to verify the feasibility and validity of this study.

Ecological evolution analysis in collective intelligence design

“…Compared with traditional models, this model can provide more collaboration design information (Zhang et al 2019). Zheng et al built a complex network-based super-network design model to solve the difficulty of expressing the design process systematically in traditional design (Zheng et al 2016). Dong et al constructed a complex network model for mechanical product design to accurately respond to changes in users' needs, which can provide clear and direct guidance for decisionmakers (Dong et al 2022).…”

Rework Quantification and Influence of Rework on Duration and Cost of Equipment Development Task

“…Complexity can be of technological, organizational, content, informational, objective, or environmental kinds. The current focus of the literature's research on project complexity is organizational and technical complexity [18,19]. Baccarini [20] discussed the meaning and specific influencing factors of project complexity from the perspectives of organization, technology, and information.…”

“…Complexity is another important factor in the rework of an equipment development task [19]. Complexity in an equipment development task consists of the sum of the complexity of the various sub-tasks and their interrelationships.…”
