In the embodiment, the fuzzy inference model processes the input training sample through a fuzzy clustering method, the fuzzy clustering method is an improvement based on the traditional clustering method, the method comprises the steps of randomly selecting a plurality of clustering centers, endowing all data points with a certain fuzzy membership degree to the clustering centers, continuously correcting the clustering centers through an iterative method to obtain an optimal clustering center, finally outputting a list of the clustering centers and membership degree values of each data point to each clustering center, and using the output data to establish the fuzzy inference model. The initial fuzzy inference model is a fuzzy inference model after the parameters are initialized, and the initial fuzzy inference model has prediction capability, but the accuracy of prediction cannot be guaranteed, and the parameters need to be further adjusted.

In this embodiment, the hybrid heuristic optimization algorithm (IQPSO-GA) is an algorithm created by combining the optimized particle swarm algorithm (IQPSO, quantum Particle Swarm Opti-hybridization) with the genetic algorithm (GA, genetic Algorithm).

For the optimized particle swarm algorithm, first, the update of the speed and the position of the general particle swarm algorithm (PSO, particle Swarm Opti-hybridization) algorithm example is determined by the following equation:

（11）

in the method, in the process of the invention,the inertial weight plays a key balance role in global searching and local searching of the algorithm;representing>The individual particles are at->Velocity vector at the time of iteration. />Indicate->The individual particles are at->Position vector at the time of iteration; />Is->Individual optimal positions of individual particles; />Global optimal positions for the whole population; />And->Is an acceleration constant; />And->Is [0,1]Random numbers subject to uniform distribution.

In this embodiment, one particle corresponds to one parameter of the fuzzy inference model, and the number of particles equivalent to the parameter of the inference model is randomly initialized through the above formula. From the above formula it is known that the fuzzy inference model has a total of 7 unknown parameter values, 、/>、/>、/>、/>、/>、/>. The number of ions is set to 7 and for each of these 7 particles, the parameters of the particles are initialized using the above formula.

OPSO (quantum particle algorithm) is an optimizing evolution algorithm established by introducing quantum theory on the basis of a standard PSO algorithm. In QPSO, the position of the particle is determined by the following equation:

QPSO introducesAnd->The co-operation and global searching capability among particles are improved, but the global searching efficiency of the particles is also influenced. To improve the particle search efficiency, we adjust the particle position from both the optimal position and the contraction-expansion coefficient of the particle. Set up- >A weighted average of the optimal positions of all particles at each iteration.

（16）

In the method, in the process of the invention,the weight coefficient for each particle is set as follows:

（17）

in the method, in the process of the invention,representing a globally optimal solution->Is>Dimension of the corresponding particle fitness function value, +.>Indicate->No. 5 of individual particles>Fitness function value of dimension.

In practical application, the adjustment of the contraction-expansion coefficient cannot be reasonably changed in the execution process of the algorithm, so that in the embodiment, an error function is defined) The distance relation between the particles and the current optimal position in the particle swarm is represented by an error function, the smaller the error function is, the closer the distance between the particles and the current global optimal position is, the smaller the searching range of the particles is, the early convergence is easy, and when the error function is larger, the farther the distance between the marked particles and the current global optimal position is, the larger the searching range of the particles is, and the convergence speed is reduced.

In this embodiment, the error function is defined as:

（18）

in the method, in the process of the invention,indicate->A fitness function of the individual particles; />Representing a globally optimal solution->And a fitness function corresponding to the particles.

Based on the definition of the error function, the contraction-expansion coefficientCan be adjusted as follows.

In the method, in the process of the invention,is indicated at +. >First->Shrinkage-expansion coefficients of individual particles; when->When larger, the +.>Taking a smaller value to accelerate the convergence rate; when->In smaller cases, the +.>And the larger value is taken, the search range is enlarged, and the sinking of local optimum is avoided.

In this embodiment, the model parameters are adaptively adjusted by using the error function, and the contraction-expansion coefficients are adjusted according to the actual situation, so as to finally obtain the optimized particle swarm algorithm.

In this embodiment, in the optimized particle swarm algorithm, the initialization of the particle swarm is random, and in the early stage of algorithm iteration, a certain dead zone exists in the population search, which not only reduces the searching efficiency of the algorithm, but also affects the stability of the algorithm, and in addition, along with the continuous iterative updating of the optimized particle swarm algorithm, the diversity of the particle swarm is reduced, and thus falls into local optimum.

In this embodiment, in order to ensure diversity of particle swarms, a genetic algorithm is introduced, and the genetic algorithm updates all chromosomes, i.e., particles, in the current population by using its own selection operator, crossover operator and mutation operator, so that the genetic algorithm has high efficiency in searching for a global optimal solution, and is used in combination with an optimized particle swarm algorithm, thereby well compensating for the defect that the optimized particle swarm algorithm is easy to fall into local optimal, and further obtaining a mixed element heuristic optimization algorithm.

To verify the effectiveness of the proposed server anomaly early warning method based on the IQPSO-GA optimized ANFIS model, we add several anomaly errors (including gaussian noise and outlier noise) on the basis of the sample data shown in fig. 5. The setting error value is shown in fig. 8 (a), fig. 8 is a schematic diagram of server hardware abnormality simulation early warning according to an embodiment of the application, wild value mutation noise is set between 450 th to 490 th groups of sample data, and the comparison result between the predicted value of the ANFIS model after the optimization by the established IQPSO-GA and the actual value after the addition of the error, and the prediction error are shown in fig. 8 (b) and fig. 8 (c), respectively. Therefore, the provided abnormal early warning method based on the IQPSO-GA optimized ANFIS model can effectively map the dynamic relationship among the information quantity change rate, the terminal current change rate and the component temperature change rate processed by the component, namely, whether the component temperature change rate is abnormal or not can be observed through input information. Once the end current or temperature of a certain component is continuously higher than the early warning threshold, the function of the component can still be used at the moment, but the following working state of the component needs to be focused, and the hardware abnormality early warning is carried out on the component.
