Research and Analysis on Assembly Methodology for the Fusion Blanket System

Table 1

Advantage and disadvantage analysis of the assembly methods.

Method	Advantages	Disadvantages
DT	It is a multidisciplinary method integrating the VR and AR technologies which has considerable advantages in information interaction between the physical world and the digital world, especially in the smart assembly of complex products.	DT is still in its infancy; its application scope is limited to the operation and maintenance, service stage of digital workshop, and production line, and it is less applied to the design, manufacturing, and assembly of product parts in the manufacturing industry.
DFA	Overall monitoring and evaluation of each stage are done during the design phase for assembly ability. It is strongly advantageous if used during the first phases of the conceptual design machine.	In the conceptual design stage, the design and assembly data cannot be used and applied when the most important product decisions are made.
PPHM	Facilitates the design of the various components of the blanket.	The decomposition of the products is very important with a detailed numbering process. If the final design or assembly has been changed from the decisions, this method will be costly
