“…The practice guidelines in the aircraft sector, for example, SAE ARP4754A states it takes into account the overall aircraft operating environment and functions but does not cover the system integration in manufacturing [43]. Research on SE implementations in manufacturing are mostly about manufacturing management and production system design [16,61,62]. Altfeld emphasizes in his book that "analyses of assembly and integration processes may well change the original layout of the product architecture" [63], which means assembly processes should provide feedback to the design.…”

“…This is a typical example of development difficulties in the manufacturing stage caused by product complexities, and the design activities of complex systems makes assembly process planning challenging. The literature shows many commercial and military aircraft projects are over cost, over budget and thus do not meet customer requirements [15,16].…”

The assembly line process planning connects product design and manufacturing through translating design information to assembly integration sequence. The assembly integration sequence defines the aircraft system components installation and test precedence of an assembly process. This activity is part of the complex systems integration and verification process from a systems engineering view. In this paper, the complexity of modern aircraft is defined by classifying aircraft system interactions in terms of energy flow, information data, control signals and physical connections. At the early conceptual design phase of assembly line planning, the priority task is to understand these product complexities, and generate the installation and test sequence that satisfies the designed system function and meet design requirements. This research proposes a novel method for initial assembly process planning that accounts for both physical and functional integrations. The method defines aircraft system interactions by using systems engineering concepts based on traceable RFLP (Requirement, Functional, Logical and Physical) models and generate the assembly integration sequence through a structured approach. The proposed method is implemented in an industrial software environment, and tested in a case study. The result shows the feasibility and potential benefits of the proposed method.

“…Milner et al pointed out that "Customer requirements and overly conservative, and in some cases required, design margins tend to drive complexity into high-reliability systems which can adversely impact producibility by driving higher costs, longer manufacturing cycle times, and poor yields once the design is transitioned into production" [17].…”

“…Integrating manufacturing considerations in bioinspired design and topology optimization, however, becomes a challenge when the manufacturing processes do not always produce the ideal quality as in the original design [8]. Meanwhile, the design process becomes a more complex problem when accounted for numerous factors and constraints [9]. Systems thinking is an approach to understand and analyze a problem as a complex whole, and it solves problems with holistic views [10].…”

A Systems Approach of Topology Optimization for Bioinspired Material Structures Design Using Additive Manufacturing

et al. 2021

Bioinspired design has been applied in sustainable design (e.g., lightweight structures) to learn from nature and support material structure functionalities. Natural structures usually require modification in practice because they were evolved in natural environmental conditions that can be different from industrial applications. Topology optimization is a method to find the optimal design solution by considering the material external physical environment. Therefore, integrating topology optimization into bioinspired design can benefit sustainable material structure designers in meeting the purpose of using bioinspired concepts to find the optimal solution in the material functional environment. Current research in both sustainable design and materials science, however, has not led to a method to assist material structure designers to design structures with bioinspired concepts and use topology optimization to find the optimal solution. Systems thinking can seamlessly fill this gap and provide a systemic methodology to achieve this goal. The objective of this research is to develop a systems approach that incorporates topology optimization into bioinspired design, and simultaneously takes into consideration additive manufacturing processing conditions to ensure the material structure functionality. The method is demonstrated with three lightweight material structure designs: spiderweb, turtle shell, and maze. Environmental impact assessment and finite element analysis were conducted to evaluate the functionality and emissions of the designs. This research contributes to the sustainable design knowledge by providing an innovative systems thinking-based bioinspired design of material structures. In addition, the research results enhance materials knowledge with an understanding of mechanical properties of three material structures: turtle shell, spiderweb, and maze. This research systemically connects four disciplines, including bioinspired design, manufacturing, systems thinking, and lightweight structure materials.
