Sampling Inspection Method of Power Grid Materials Based on Analytic Hierarchy Process

Daily sampling inspection is crucial for identifying and eliminating hidden dangers in power grid materials. However, traditional sampling inspection methods that rely on experience often lead to a wastage of resources and manpower. Hence, there is a need to find a suitable method for sampling inspection of power grid materials. This paper proposes a mathematical model to evaluate the quality level of power grid materials in the sampling inspection process. The model involves data cleaning of the original data of power grid materials to obtain the standard data of operational quality. The analytic hierarchy process is then used to analyze the standard data of material quality, enabling the determination of the quality level of each supplier’s materials. Based on the theory of Acceptance Quality Limit, the foundation of the sampling inspection method for each supplier’s materials is established.
