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 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.
