The dual-resource integrated scheduling model of AGV and machine was established by comprehensively considering constraints of machines, workpieces and AGVs. The bidirectional single path fixed guidance system based on topological map was determined, and the AGV transportation task model was defined. The improved A* path optimization algorithm was used to determine the optimal path, and the path conflict elimination mechanism was described. The improved NSGA-Ⅱ algorithm was used to determine the machining workpiece sequence, and the competition mechanism was introduced to allocate AGV transportation tasks. The proposed model and method were verified by a workshop production example, the results showed that the dual resource integrated scheduling strategy of AGV and machine is effective.展开更多

However, as it is a key factor in market competition, it should also be subject to competition law. In most jurisdictions, restriction of competition related to IP rights is not a black and white question, and such rights are challenged only when the IP owners hold market power and when protection of their fights has a serious and unreasonable effect on competition. In assessing IP-related restriction of competition, we need to analyze several elements： we have to define the relevant markets, identify the parties concerned, determine their market share, assess the anti-competitive effects of the controls, etc.. China＇s existing legislation is not adequate to solve problems arising from IP-related restriction of competition. Nevertheless, the process of China＇s legislation on this issue shows clearly that the misuse of IP rights for the purpose of excluding or significantly restricting competition is not justifiable under competition law.展开更多
