Quantitative and Meticulous Methods to Aero-engine Assembly Process

Manual operation and paper document based management are the bottleneck to the quality and efficiency of aero-engine assembly process. A set of optimization methods is presented about the aero-engine assembly process. From the technical point, the model of LoA (Level of Automation) was expanded with the addition of the role dimension and task dimension to construct a quantified method of level of assembly information automation, which was utilized to guide the digitalization of assembly process. From the management point, the meticulous management was utilized to improve the microcosmic operation and macro flow control of assembly. A refine and quantified assembly digital system for aero-engine has been developed to verify the effectiveness of the optimization methods.
