Abstract This paper presents a method for assembly evaluation. The method uses two evaluation criteria, robustness and variation analysis, and is supported by a software tool developed by the authors. The robustness evaluation aims at detecting design and assembly solutions that are sensitive to variation and may cause problems during production. Using this method in early product and process design phases helps to find more robust concepts, resulting in shorter production start-up time and better precision. The method’s use is exemplified in a concept study of the assembly process of the door to the body of a (fictitious) jeep. The study shows that the proposed method can be used to obtain an objective comparison between different concepts. This comparison includes both general robustness and the expected variation in the critical dimensions. The results can be used, together with economical and practical aspects, to determine which concept is best suited for the assembly process. The software used is implemented in the MS Windows environment and has an JGES interface that enables the user to import CAD geometry from an arbitrary CAD system. It can perform different types of robustness evaluations as well as traditional variation analyses.

Unique characteristic of system of system based product life cycle challenges evolves different level of systems. This means the product design system and process level system consideration are very important besides the system level issues for product and process development which are part of systems of system. These core issues include the physical elements, assembly process and its related cognitive elements of component to that particular assembly and its process at Sub system level which are fundamental of System of system in holistic perspective of new product and process design. Any system level change or variety affects the next adjacent system in the same product as a member of same family of a system of system. In this paper the aspect of Hybrid electric car battery has been explored to reduce the system of system level sociotecnical complexity in product design. In this context, the affect of changeability in the assembly system level has been explored and DFA analysis and the complexity Index of the product at physical structure, assembly process and cognitive system level been discussed to draw analogy for making an understanding of similar nature of the system in platform based product and process family development.

Assembly Sequences

Assembly Sequence Planning (ASP) is an essential question for aircraft assembly process design. Modern aircraft assembly contains plenty of complex shape components, which have so many assembly features to ensure, this leads to a large number of feasible assembly sequences using traditional sequence planning algorithms; and it is hard to evaluate the contribution to assembly quality for every sequence. A methodology called Key Characteristics Based ASP is proposed in this paper, which can significantly reduce unavailable sequences and ensure key features for quality in assembly process designing compared with previous methods. The methodology focuses on the final assembly quality and considers it as Assembly Key Characteristics (AKCs) in the beginning of assembly process design. With tools such as AKCs decomposition, Datum Flow Chain, precedence constraint matrix, the methodology describes the main process for ASP. To verify the technologys effectiveness, this paper presents an application of the algorithm in an aircraft component assembly by an 863 program.

In order to improve the quality, efficiency and cooperativity of aircraft assembly, based on the analysis of the characteristics of aircraft assembly process, a method for assembly process design, simulation and application based on three dimensional (3D) product model was proposed. The basic working process and system structure of the method were introduced, and the 3D digital assembly process planning, design and simulation optimization application mode was explored. This method has been applied in the design of aircraft assembly process, the efficiency and synergy of process design have been greatly improved.
