Manufacturing of aircraft structural parts has the characteristics of multi-varieties, complex structure, and small batch which result in high difficulty and workload of the processing planning. When the project leader is deciding the assignment of processing planning tasks, two main factors which affect the reliability of the processing plan need to be considered: the capability of the planners and the complexity of the structural parts. This paper proposes a fuzzy comprehensive evaluation method to evaluate these two factors. The reliability of processing plans is predicted by using the two impact factors and evaluated by using the machining results both based on the fuzzy comprehensive method. A project case study is taken to demonstrate the usability of the proposed method and the test results show that the proposed prediction method is feasible and practicable.
