[0002] Aircraft onboard systems and equipment are the basic conditions for normal flight, information perception and processing, control and maneuvering of aircraft. They are the eyes, ears, brain and nerves of aircraft. The normal operation of aircraft onboard systems is crucial to flight safety. Supply chain quality management is crucial to ensure the excellent performance, flight safety and strict standards of aircraft onboard systems and equipment. However, the current quality monitoring system of the supply chain of aircraft onboard systems and equipment faces severe challenges, mainly manifested in the difficulty of monitoring and the imperfect monitoring mechanism. In particular, the management of supply chain quality still mainly relies on post-testing and feedback. This lag greatly limits the timely discovery and efficient resolution of quality problems.

[0096] S3, based on the supply influence of each supply entity, the supply relationship of each supply entity, the supply influence threshold and the supply relationship threshold, the classification of each supply entity is obtained. The classification includes strategic type, bottleneck type, leverage type and general type.

[0097] Specifically, if the supply influence is greater than the supply influence threshold and the supply relationship degree is greater than the supply relationship degree threshold, then the current supply entity is strategic; if the supply influence is greater than the supply influence threshold and the supply relationship degree is less than or equal to the supply relationship degree threshold, then the current supply entity is leveraged; if the supply influence is less than or equal to the supply influence threshold and the supply relationship degree is greater than the supply relationship degree threshold, then the current supply entity is bottleneck; if the supply influence is less than or equal to the supply influence threshold and the supply relationship degree is less than or equal to the supply relationship degree threshold, then the current supply entity is general.

Preferably, the weight of the strategic type is 0.4; the weight of the bottleneck type is 0.3; the weight of the leverage type is 0.2; and the weight of the general type is 0.1.

[0116] Specifically, if there are multiple supply entities in the same grade, the supply entity corresponding to the current grade will score the weight corresponding to the current grade.

[0117] The risk of the aviation airborne system equipment supply chain can be obtained by comparing the obtained quality value of the aviation airborne system equipment supply chain with the maximum quality value.

[0118] Specifically, the supply chain includes supply entity A, supply entity B, supply entity C, supply entity D and supply entity E as an example.

[0119] Furthermore, taking supplier A as an example, the interruption of supply of key products of supplier A will have a serious impact on aircraft production, so the supply impact is 0.9, and the supply impact threshold is 0.8. The key products of supplier A have poor substitutability in the market, so the supply relationship of supplier A is determined to be 0.9, and the supply relationship threshold is 0.8, so it can be determined that the classification of supplier A is strategic.

The quality assessment value of supplier A is 85×0.6370+90×0.2636+

[0122] 80×0.1104=86.701. Since supplier A is only involved in the management of aviation materials and spare parts, the total quality assessment value of supplier A is also 86.701.

[0123] The supply progress value of supplier A is 94.74, with a weight of 0.4; the product quality value is 99.19, with a weight of 0.4; the service level value is 71, with a weight of 0.2. The total quality performance value of supplier A is 99.772.
