“…However, this method requires a lot of computing resources to generate sequence diagrams, and the infeasible sequences must be removed in the process. Shyamsundar and Gadh [57] present a regressive approach that takes into account both the separating direction and decomposing direction to disassemble the components of the target product. However, these approaches lead to many paths, so it takes a lot of time to find a solution.…”

Global warming and climate change are currently the world’s most pressing issues. The causes are the results of people pursuing a better quality of life and a material civilization. Thus, if the concept of green design can be applied when designing and manufacturing products, it will greatly reduce the environment impact of such production. This paper addresses a novel green design method based on the extension theory and concept of Green DNAs, which embraces the concepts of green technology, green material, and green manufacturing. The proposed method can provide designers with a decomposing–recomposing approach with rigorous logic and deduction processes for transforming general products into green products. It can also facilitate the use of green modular approaches in product design and improve product disassembly to raise the value added by product recycling. It offers companies concrete guidance and detailed steps to apply in green product design. Finally, a practical green product design of a medical air purifier is demonstrated to validate the feasibility and effectiveness of the proposed method.

“…Gadh and Srinivasan [22,23] proposed the greedy search algorithm, called the wave propagation algorithm, which searches the shortest path to access the target component without violating the precedence relations. In order to support the topological graph which satisfies the precedence relations, they developed the geometric abstraction scheme to identify the collisions among components [24][25][26]. Recently, Li et al [1,27,28] developed a disassembly planning system designed for maintenance.…”

“…Figure 9 shows the basic idea of finding the disassembly directions of a three-dimensional polyhedral component. In order to generalize the disassembly direction, the Gaussian sphere is used widely by recent publications [24,25,28,[55][56][57][58], while some authors use the predetermined axial direction [14,52,54] and the vector expression [53]. For this subject of feature recognition and virtual disassembly, there are many publications [59-61].…”

“…Unlike the complete and/or incomplete disassembly based approaches, Shyamsundar and Gadh [24] presented a method to find the disassembly sequence required for selective robotic disassembly where a target component is given, which finds the directions of components to be removed. Later, Srinivasan and Gadh [23] proposed a wave propagation method to determine the locally optimal disassembly plan using the geometric computer-aided design (CAD) model of a product in order to reduce the complexity for optimal sequencing in the selective disassembly problem (see Fig.…”

“…However, if the precedence relations can be used in the early stage of the disassembly sequence generation before full enumeration, the computational complexity to generate all possible disassembly sequences will be much lower than that of the full enumeration methods. For instance, the disassembly directions of products, which consider directions with freedom from interference of each component, are used to find feasible disassembly sequences [14,24,25].…”

This paper surveys the disassembly sequencing problems in which used or end-of-life products are disassembled into basic parts and components, especially due to repair and maintenance. Disassembly theory is applied to complex products such as mechanical, electromechanical and electronic appliances. Here, the disassembly sequencing includes feasible disassembly sequence generation and sequence optimization. Also, product representation issues are included for feasible disassembly sequence generation. This paper covers a state-of-the-art review on assembly/disassembly planning that can be used for disassembly sequencing for maintenance and gives a broad view of disassembly planning for maintenance and a basis for disassembly related research.
