目前国内集装箱码头堆场多数采用轮胎式集装箱起重机(以下简称轮胎吊)作业,随着用工成本的增大、操作人员要求劳动强度降低、作业效率要求的提升,各大港口码头和堆场都在积极研究和开展轮胎吊自动化改造技术。文中结合轮胎吊自动化的难点,研究分析了轮胎吊起升钢丝绳八绳单独缠绕系统在轮胎吊自动化应用。 相似文献

The paperless office or factory is often spoken of as the place of the future, but would such on environment actually work? The author considers the role of shop floor data collection (SFDC) in automatic information flow throughout the manufacturing process. He concludes that several MRP II systems have the capability to automate transactions to a greater or lesser degree, mostly aimed at capturing inventory movements from SFDC systems. However, the scope to automate complete sets of business transactions exists in a great many areas throughout all businesses. Such automation allows manual effort to be concentrated where real decisions are needed by removing non value adding tasks 相似文献

Knowledge-based systems have made their mark in improving many manufacturing processes, but there is still a stumbling block in the process of converting human knowledge into a form where a computer or expert system can use it. The authors describe a successful way of deriving knowledge directly from raw data. The data gathered are processed for all shifts over a period of seven days to produce, for each shift, a value for the productivity variables. 相似文献
