Financial crisis leads to the demand reduction in western countries, and as the largest manufacturing country, China must face overproduction. The role of China as "world factory" determines that fi nancial crisis will severely attack Chinese manufacturing industry. The unsustainable development of Chinese manufacturing industry is mainly reflected in the following aspects: heavy dependence on export, low-level manufacturing link, lack of modern service industry and high-tech industry, weak independent innovative ability, unsustainable exploration of heavy-pollution resources, and lack of international famous brands. How to transform crisis to opportunities is an urgent research topic. Under the circumstance of financial crisis, Chinese manufacturing industry has more external drives to change the current situation. Therefore, financial crisis becomes not only an opportunity for Chinese manufacturing industry to improve itself based on the existing accumulation but also a chance for China to transform from "world factory" into a powerful nation of manufacturing industry in the world.展开更多

关于智能制造,前人已发表了很多文章。其大多数内容都集中在硬件、软件、增材制造、机器人、物联网(Internet of Thing,IoT)以及工业4.0等话题,而对另一些极重要的领域却少有讨论,如混合系统、先进制造业重定义、新制造的基本构成元素...关于智能制造,前人已发表了很多文章。其大多数内容都集中在硬件、软件、增材制造、机器人、物联网(Internet of Thing,IoT)以及工业4.0等话题,而对另一些极重要的领域却少有讨论,如混合系统、先进制造业重定义、新制造的基本构成元素、制造业生态系统准备水平及技术可扩展性等。本文将通过实例,从全新的视角,为读者剖析这些领域中目前的四个挑战。挑战一:当我们希望提高公众对新制造业经济及其社会影响的认识水平,并获得政策制定者的明确支持时,应如何重新定义未来制造业。挑战二:如何正确认识到未来制造业的关键词是"混合"。它具有人类与机器人协作、增材制造与减材制造结合、金属材料与复合材料并用以及网络系统与物理系统融合等特点。因此,划定界限与制定标准变得尤其重要。挑战三:如何开发一个同时对技术、制造商业化和新制造生态系统做出评估的通用框架,以缩短生产到交付之间的时间;以及在该框架下,如何进一步制定一套可被广泛采用的、针对非信息技术的可扩增性测量的标准。最后,也是同样重要的是挑战四:如何通过公司多方合作,来验证"产-学-政"三位一体的模型是否成功。本文将详细讨论上述四大挑战。展开更多
为更好预测全国碳价走势,基于带有外生变量的自回归差分移动平均模型(autoregressive integrated moving average with exogenous variable model,ARIMAX),分履约期和非履约期使用不同的外生变量分别构建了全国碳价预测模型。首先,基于...为更好预测全国碳价走势,基于带有外生变量的自回归差分移动平均模型(autoregressive integrated moving average with exogenous variable model,ARIMAX),分履约期和非履约期使用不同的外生变量分别构建了全国碳价预测模型。首先,基于对全国碳市场制度规则研究和交易特征分析,识别出全国碳价在非履约期主要受参与者预期的影响,在履约期碳价主要受企业履约需求驱动;其次,在模型训练方面,采用一种自回归差分移动平均模型,在不同阶段引入不同的外生变量来提升碳价预测效果;最后,基于全国碳市场第一履约期真实价格数据验证结果表明,所提的全国碳价预测模型在准确性方面优于基准模型。展开更多
