Many companies have developed corporate database systems and/or management information systems, some have established intelligence units. However, the systems often fail to scan the external environment to which the companies are exposed, and fail to yield meaningful intelligence, thus overwhelming managers with internal data. Argues that to address the information needs of top marketing managers, the environmental factors that have immediate effects on the company′s operation should be identified. Computer‐based information systems could play an important role in collecting environmental information from various sources; however, in interpreting data and disseminating intelligence to marketing managers, a human‐computer mixed system is essentially required. The system would be used in conjunction with a corporate database system to present intelligence to marketing managers, so as to keep them instantly informed, reinforce their knowledge learning, and support their decisions. Highlights the critical factors for developing and utilizing such systems. The approach adopted is to examine managers′ working style and decision processing, to develop a framework of environmental scanning, human‐computer‐based data filtering, interpreting, and intelligence reporting system with natural interface.

At present, one of the key equipment in pillar industries is a large rotating machinery. Conducting regular health monitoring is important for ensuring safe operation of the large rotating machinery. Because vibrations sensors play an important role in the workings of the rotating machinery, measuring its vibration signal is an important task in health monitoring. This paper aims to present these.
In this work, the contact vibration sensor and the non-contact vibration sensor have been discussed. These sensors consist of two types: the electric vibration sensor and the optical fiber vibration sensor. Their applications in the large rotating machinery for the purpose of health monitoring are summarized, and their advantages and disadvantages are also presented.
Compared with the electric vibration sensor, the optical fiber vibration sensor of large rotating machinery has unique advantages in health monitoring, such as provision of immunity against electromagnetic interference, requirement of less insulation and provision of long-distance signal transmission.
Both contact vibration sensor and non-contact vibration sensor have been discussed. Among them, the electric vibration sensor and the optical fiber vibration sensor are compared. Future research direction of the vibration sensors is presented.
