Finally, a prototype system for rapid diffusion of blade manufacturing process is developed. The main contents of this paper are as follows: 1. Based on the basic element theory, a hierarchical model of blade manufacturing process diffusion is constructed, and three levels of information models are designed: manufacturing task layer, manufacturing process layer and manufacturing resource layer. Based on the hierarchical model, the connection mapping relationship between adjacent layers and the matching relationship between task and resource are designed, and the process of manufacturing resource selection based on manufacturing task is given. 2. A method to solve the contradiction problem of extension transformation manufacturing process is proposed. The mechanism of blade manufacturing process diffusion and the diffusibility of blade manufacturing process are analyzed. The blade manufacturing process diffusion process and conflict resolution process are designed.

The influence of adjusting process on diffusion manufacturing is analyzed, and the influence value of adjustment process is obtained by introducing the relation matrix and the method of case search. On the basis of influencing constraints, the diffusion process adjustment scheme in accordance with the demand of the main enterprise is generated through the calculation of multidimensional correlation function. 4. A rapid diffusion verification system for blade manufacturing process is designed and developed in combination with the proposed theoretical and technical methods. The feasibility and effectiveness of the theoretical and technical methods are preliminarily verified.
