The invention discloses a troubleshooting strategy evaluation method and device based on multiple factors, and the method comprises the steps: constructing a troubleshooting model according to a preset troubleshooting strategy, wherein the troubleshooting model comprises a multistage system composition node, a plurality of fault nodes, and at least one problem node; determining all problem nodes in the troubleshooting model, and determining a processing path corresponding to each problem node and a system composition node connected through a problem index path; respectively determining a processing path and a fault node corresponding to a system composition node, and performing normalization processing on a plurality of pieces of preset factor weight information corresponding to the faultnode to obtain a normalized factor weight vector; and performing calculating according to a preset fault factor incidence matrix and the factor weight vector to obtain a score value, and evaluating the troubleshooting strategy according to the score value to obtain an evaluation result. According to the invention, the technical problem of blank evaluation of troubleshooting strategies in the priorart is solved.
Description
technical field [0001] The present application relates to the technical field of troubleshooting strategy evaluation, in particular to a method and device for evaluating a troubleshooting strategy based on multiple factors. Background technique [0002] The troubleshooting strategy refers to gradually narrowing down the scope of troubleshooting through clues such as the environment and conditions, and finally locating the fault. An excellent troubleshooting strategy has fewer steps and more accurate positioning. [0003] At present, there are many troubleshooting strategies, such as fault tree analysis (Fault Tree Analysis, FTA), problem-guided troubleshooting methods based on ontology models, etc.; among them, the basic principle of the troubleshooting strategy is: to establish a troubleshooting model, and then Evaluate problem handling and normalize with troubleshooting models. However, the same troubleshooting strategy can be used to establish a variety of different trou...
