The invention discloses a product early-fault root cause recognition method based on fuzzy data processing. The method comprises the following steps of 1, constructing a product early-fault root cause relevance tree layer model; 2, constructing a potential fault root cause data model; 3, collecting product service life period quality and reliability data; 4, on the basis of the fault relevance tree layer model, a process target node and data fuzziness analysis are determined, and then node influence factors and fuzzy values are determined; 5, constructing a product early-fault root cause fuzzy data envelopment analysis model; 6, estimating an efficiency evaluation value of a fault relevance tree node; 7, fault relevance node relative weights are divided, and node priorities are ranked; 8, results are analyzed, and fault root cause recognition is completed. Development of the early fault root cause recognition technology under the early fault mechanism recognition cognition fuzzy environment is broken through, prevention measures are adopted for product design, technological design stage and other early fault forming stages, afterward treatment is changed into beforehand prevention, and the new idea is provided for early fault prevention and rectification.

The invention discloses a deployment method for a micro-operation system with a self-adaptive transmission model. With the method, the transmission model of the micro-operation system is adaptively constructed through comparing a node scale N in a cluster and the size of the node number M synchronously deployed by a TFTP server at most. When N is smaller than or equal to M, the micro-operation system is deployed by adopting a C / S transmission model; when M is smaller than N, and N is smaller than or equal to 2M, the nodes are deployed in batches by adopting the C / S transmission model, and thebatching method overcomes the disadvantage that the deployment of the micro-operation system is failed caused by excessively heavy load of a TFTP server side; when N is larger than 2M, the C / S transmission model is automatically evolved into a multi-way tree transmission model, and by converting the nodes partially loaded with the micro-operation system into nodes which can provide TFTP service, the micro-operation system is deployed to each node in the tree layer-by-layer and in batches. The multi-way tree transmission model overcomes the bottleneck problem of the deployment of the single TFTP server, has better expandability, and deployment ability exponentially increased along with increase of time. The method is effective and realizes the deployment process of the micro-operation system in the multi-node computing system reliably.

The invention discloses a graph spectrum and reachable path number-based sub-graph query method for an undirected weighted graph. The method comprises the steps of 1, calculating codes of node marks of a query graph and graphs in a known graph data set, codes of weighted adjacent edge marks and a code of a reachable path number; 2, generating graph spectrums of the query graph and the graphs in the known graph data set; 3, by using the codes of the node marks of the graphs in the known graph data set, the codes of the weighted adjacent edge marks, the code of the reachable path number and thegraph spectrums, constructing an index tree; and 4, comparing the query graph and the node graphs of the index tree layer by layer from top to bottom, and meanwhile, performing screening, until the bottommost layer is screened out, wherein the obtained graphs are candidate graphs similar to the query graph. According to the method, the topological information of the graph is better described. Meanwhile, the features are coded, so that the storage is easy, the operation is simple, the comparison between the features can be accelerated, and the query speed of the whole sub-graph can be increased.

The invention discloses a distributed cluster management method for map cache slices based on a quadtree layered grid, which uses a quadtree layered grid algorithm to realize a distributed cluster of map cache slices, and distributes map cache slices based on spatial geographic regions. Cluster management ensures that the spatial and geographical areas that users really care about get higher performance and improves the rationality of cluster resource utilization. The downtime of a cluster grouping node will only affect the spatial geographic area corresponding to the cluster grouping, and will not affect other spatial geographic areas, thereby improving the robustness of the cluster.

The invention provides a method for generating a multi-fan-out clock signal for a superconducting RSFQ circuit, and the method comprises the steps: building an SPL tree with the height P being 1, with the SPL tree with the height P being 1 comprises a single node, an SPL2 and an SPL3, and storing the single node, the SPL2 and the SPL3 into a set R; calculating the maximum height Pmax of the SPL tree according to the N; establishing the SPL tree layer by layer, and increasing 1 to P in each iteration until P is larger than Pmax; wherein the tree with the height being P is composed of sub-trees with the height smaller than P in the set R, when the SPL tree is established every time, according to an objective function, the objective function value of the established SPL tree is compared with that of the SPL trees with the same height and the same leaf node number in the set R, and only the tree with the minimum objective function value is stored in the set R, selecting a tree with N leaf nodes in the set R to form an optimal solution; and determining a branch path formed by the SPL of the multi-fan-out clock signal according to the optimal solution.
