物联网技术的广泛应用有效改善了煤矿安全生产和事故救援工作的效率,有针对性地对物联网资源进行配置和对煤矿事故救援物资的高效调度,可以有效降低煤矿事故造成的损失。考虑到煤矿生产和事故救援的特殊性,设计了煤矿安全生产和救援资源监管物联网系统框架,对物联网资源进行了整合,同时根据煤矿事故救援调度具体特点,构建了基于物联网的煤矿应急救援多Agent自动协商调度系统模型,模型利用从物联网实时获取的事故和救援物资信息自动完成救援物资优化调度方案设计,并可以根据事故和资源调度情况动态完善调度方案。最后利用Jade技术对系统模型进行了实现,并通过模拟仿真,证明了模型的有效性和合理性。

中国职业教育学科建设已走过百年历程。从诞生初的高起点(1917～1949)、建国初的销声匿迹(1949～1980)到重建时的鲜有问津(1980～2004)再到现如今的百花齐放(2004～至今)。反思百年历程,内在建制拘囿于"照着讲"和外在建制受限于"教育学"是困扰中国职业教育学发展的核心挑战。为此,我们需要通过保持本土自觉、坚守实践立场和创生中国范式实现从"照着讲"到"接着讲"的转变,同时,通过增强职业教育学人学科认同感和完善职业教育学科人才培养体系,凸显职业教育学的重要地位。

肇始于1917年的中国职业教育学,迄今求索已百年有余。从知识社会学的视角考察可以发现,除特定时代背景外,研究群体所独有的理想抱负、知识结构以及实践经历,共同造就了职业教育学"学习西方职业教育理论,指导中国职业教育变革"的社会使命。近代中国职业教育学的发展因此呈现出"译介与中国化"的双重特质:职业教育学人以学会和大学为主要阵地,先假道日本与欧美,编译出版了大量职业教育理论书籍;其后伴随着中国职业教育实践的不断深化,秉承"贴近中国现实"学术自觉的学者们最终创生出具有本土特色的职业教育理论。
