It proposes the following aspects. First, the focus of energy supervision should shift to in-process and post supervision after cancellation or decentralization of energy project approval, Hence, the supervision over construction and completion acceptance is reinforced. Second, with the progression of marketoriented reforms in tire electricity and petroleum sectors, relevant energy authorities should strengthen supervision on key aspects in the electricity and petroleum sectors, particularly by way of specific supervision and problem supervision, in order to keep tire market fair, open and transparent. Third, innovative supervision modes should be adopted to improve supervision performance, so as to realize effective supervision amt finally achieve standardized and normalized energy supervision. These proposals rtTresent both the challenges and tasks that the supervision authorities face but also highlight important chances to realize the energy supervision revolution. Energy enterprises should continuously update thenzselves on the reforms and actions of energy supervision in order to meet the compliance requirements of construction and operation.展开更多

Rather than focusing all attention on safety issues of working faces, supervising departments of coalmines are advised to pay much more attention to institutional factors that may impact people’s attitude and behavior, which are responsible for most coalmine accidents. It is believed that such a shift of attention can effectively reduce coalmining production accidents and greatly enhance supervision efficacy.展开更多

In the market competition, many enterprises focus on how to occupy a larger share. Too much emphasis on the improvement of production efficiency leads to the serious neglect of the quality of many products, which seriously hinders the long-term development of enterprises. In order to do a good job in product production, the existing quality supervision must be continuously optimized and improved. Measurement and testing technology is very important in the market supervision and management. Taking Chengwu as an example, this paper analyzes the application value of this technology in the market supervision and management, and clarifies the relevant matters needing attention in the application of measurement and testing technology, hoping to provide some reference and inspiration for relevant workers.展开更多

Using the moving data windows technique, the static MPCA is extended for use in dy-namic process performance monitoring. The control chart is set up using the historical data collected from the past successful batches, thereby resulting in simplification of monitoring charts, easy tracking of the progress in each batch run, and monitoring the occurrence of the observable upsets. Data from the commercial-scale penicillin fer-mentation process are used to develop the rolling model. Using this method, faults are detected in real time and the corresponding measurements of these faults are directly made through inspection of a few simple plots (t-chart, SPE-chart, and T2-chart). Thus, the present methodology allows the process operator to actively monitor the data from several cultivations simultaneously.展开更多
