复杂开放水域的无人船避障路线蚁群规划算法

为了改善避障效果,获得具有较少拐点的最短避障路线,设计复杂开放水域的无人船避障路线蚁群规划算法。在复杂开放水域障碍物栅格化处理的基础上,基于蚁群算法基本原理,获取势场合力、目标点的位置信息相结合的综合启发信息,优化信息素浓度增量,改进状态转移概率,进行蚁群算法的改进处理,实现无人船避障路线规划。结果表明,该算法可实现无人船避障路线规划,设计的避障路线长度相比改进前降低了40.39%、拐点数减少60%。

Discussion and Research on Enterprise Supply Chain Management under the New Economic Background

The market environment and the competition characteristics between the enterprises is different from the traditional competition, the competition between individual enterprise is displaced by the comprehensive strength of alliance supply chain which formed by upstream and downstream suppliers and customers whose main body is core enterprise, whether production enterprise or retail business are inevitably to form as chain so that to obtain the relative cost advantage and quick reaction advantage in the fierce market competition. Combining the theory and practice comparison of enterprise supply chain management at home and abroad, we can find that the theory and practice of Chinese enterprises supply chain management are falling behind developed countries In the new economic background, research and discussion of China＇ s enterprise supply chain management theory and practice, is helpful to promote the enterprise comprehensive competition ability and improve the economic benefit of enterprise.
