A method and system for inconsistency resolution in a model-driven software development environment are provided. A method includes performing a safety analysis for resolutions in response to detected inconsistencies to determine whether the resolution, if implemented, will lead to a resolution cycle when applied to a given inconsistency. The determination includes processing a resolution tree for the inconsistency and, using a resolution strategy tree, for each resolution that resolves an inconsistency, analyzing whether beginning with the resolution, it is possible to resolve all the inconsistencies subsequently introduced as side effects without a resolution cycle occurring. The analysis includes traversing the resolution strategy tree, whereby all resolution strategies derived by traversing the resolution strategy tree lead to a resolution cycle if the resolution strategy tree is infinite. The method includes categorizing the resolution that resolves the inconsistency and applying a resolution for the inconsistency based upon the resolution category.

The invention provides a locomotive intelligent operation optimization calculation method. The locomotive intelligent operation optimization calculation method comprises steps that step 1, information required by locomotive intelligent operation optimization is preprocessed; step 2, an initial optimization curve is generated; step 3, optimization adjustment is carried out based on speed limit; step 4, optimization adjustment is carried out based on time deviation; step 5, the optimization curve is adjusted based on a requirement on operation steady safe shifting, and a final optimization strategy is generated. The strategy of every step is affected by locomotive driving strategy influencing parameters, which are matched with different strategies under different conditions, and are used as strategy classification attribute for strategy classification. The strategy of every step can be used to form a strategy tree, the leaf node of which is the matched final optimization strategy according to the classification attribute. Every step of the whole scheme is capable of satisfying the schedule requirement, the speed limit requirement, the time table requirement, the steady operation requirement, the energy saving requirement, and other requirements of the locomotive operation, and optimization effect and integrated operation efficiency are guaranteed.

The multi-classification strategy-based fault diagnosis method for train air-conditioning units disclosed in the present invention is as follows: first, according to the distribution characteristics of the actual normal operation data and various fault operation data of train air-conditioning units, calculate the distribution density of each class, and then calculate the distribution density based on dead knot distribution density Sorting is carried out, and finally a binary classification strategy tree based on PSVM is constructed by using the sorting results, and the fault diagnosis model of the train air-conditioning unit is obtained through learning and training, so that the fault diagnosis model of the train air-conditioning unit is used to diagnose and determine the fault type of the train air-conditioning unit. The multi-classification strategy-based fault diagnosis method for train air-conditioning units disclosed by the invention can effectively improve the accuracy of fault diagnosis.

The invention provides an FPGA (Field Programmable Gate Array) based high-speed network strategy matching method. The method realizes utilization of relatively small storage space, and simultaneously is suitable for fast strategy matching processing in hardware, and further enables the performance of strategy matching processing to be irrelevant with the data volume of strategies. The FPGA based high-speed network strategy matching method employs a quintuple, supports accurate matching of the quintuple and IP-port range matching , and is stronger in functions and more diversified in matching conditions and matching modes than the traditional pure hardware manner; the strategy tree of the FPGA based high-speed network strategy matching method is a specific tree structure with a node length fixed at 512 bytes and the height of the tree layer fixed at 13, and aims at FPGA strategy matching; the logic processing of direct address positioning is simple and efficient, so that consumption of lots of time on the logical operation is avoided and the matching efficiency is greatly improved.

The invention is applicable to the traffic engineering field in network communication and provides a management method and a management system of an HQoS strategy tree. The method comprises the following steps: step 1, assigning an unassigned subtree which is in the existing tree and has the same number of layers as the number of the layers of a strategy tree required for HQoS application to the HQoS application; step 2, updating a root node and a parent node of the subtree after assigning the subtree until acquiring use information of the root node of the existing tree; and step 3, at the end of use of the subtree for the HQoS application, releasing the subtree and updating the root node and a parent node of the subtree until acquiring the use information of the root node of the existingtree. The management method helps only assign the tree required by the HQoS application to the HQoS application without waste of node resources of the tree.

A method for applying a strategy to a dataset in a data mining system to address a business problem, comprising: receiving at least one conditional expression defining the strategy from a user through a graphical user interface (“GUI”) displayed on a display screen of the data mining system; applying the conditional expression to the dataset to split the dataset into segments; displaying the segments as nodes in a tree structure on the display screen; receiving a calculation expression for operating on one or more values in one or more of the segments; applying the calculation expression to one or more of the segments to generate one or more respective calculated values; displaying the one or more calculated values in respective nodes of the tree structure; receiving a treatment expression for operating on the calculated values; applying the treatment expression to one or more of the calculated values to generate respective responses to the business problem; and, displaying the responses in respective nodes of the tree structure to thereby address the business problem.
