从可扩展性、通用性和工作模式考虑,采用B/S模式和C/S模式相结合的3层应用体系结构构建基于协作交互的列车运行图网络化编制系统。系统由客户端(用户服务层)和服务器端(Web服务层/应用服务层/数据服务层)组成,包括用户及协同控制子系统、基础数据管理子系统、站群管理子系统、运行图编制和调整子系统、机车交路管理子系统、指标和能力分析子系统以及基础技术支撑和延伸服务等其他子系统。给出时刻表规化模型、车站技术作业规划模型和机车交路勾画模型以及网络协作方式。通过原型系统的开发和在哈尔滨铁路局的试运行表明,构建的基于协作交互的列车运行图网络化编制系统在技术上是可行的。 相似文献

With fisheries declining, coral reefs battered, mangrove forests under threat, pollution levels rising, and coastal communities experiencing increased poverty, the Philippines faces severe challenges in managing its coastal resources. Coastal management efforts began in the Philippines more than 20 years ago through various community-based projects. Now, integrated coastal management is expanding in the country and holds the potential to reverse the trends. This article analyzes the situation in relation to new approaches for coastal management being undertaken through the Coastal Resource Management Project supported by the United States Agency for International Development implemented by the Department of Environment and Natural Resources. This project, drawing on the lessons generated by past and ongoing coastal management initiatives, is emphasizing integrated approaches to management over narrowly focused fisheries management and habitat protection efforts. It highlights the increasingly important role of local governments and the changing roles of national government to effectively support integrated coastal management. Multisectoral collaboration is explained as standard procedure to achieve outcomes that are broad based and sustainable. Local and national level activities are contrasted and shown as essential complements in building institutionalization of resources management within all levels of government. A practical result framework is explained for measuring relative success at the local government level of implementing best practices for coastal management. Finally, lessons being learned related to collaboration, level of focus, education, and communication; who is responsible; and expansion of the project are highlighted. 相似文献
