**Description**
Regarding the development of an aircraft assembly process, this paper will illustrate the intelligent decision-policies of the aircraft assembly process based on technician experience. The model of aircraft assembly process knowledge management system to avoid the complexity of the aircraft or aircraft product assembly process will be analyzed here. According to the characteristics of the aircraft assembly process knowledge management system, the aircraft assembly process has been discussed to realize the decision of the aircraft assembly process. Then aircraft assembly process intelligent decision-making has been established based on the aircraft assembly process knowledge management system and aircraft assembly process library that is oriented to the assembly process requirements using a reasonable assembly process reasoning method. This paper will illustrate the aircraft assembly intelligent decision model based on expert tacit knowledge and development of decision system of aircraft assembly process by using the development of the Oracle database. Finally, the intelligent decision policies of the aircraft assembly process are based on tacit knowledge which are applied to the decision-making for the fastener hole calibration process. A particular innovation on switching algorithm for aircraft assembly process intelligent decision-making considers the expert’s knowledge information. The value of this research is to complete the aircraft/aircraft product assembly process efficiently, to reduce the assembly time, to avoid the assembly mistake, to reduce the assembly cost, and flexible assembly process.
