However, a comprehensive and systematic research, especially strategic models based on empirical studies, is required in the public library strategic planning. The purpose of this research is to investigate the current practices and propose an appropriate reference and guidance of strategic planning in public libraries in China’s mainland.Design/methodology/approach: A questionnaire-based survey method is carried out to collect the views of public libraries staff at different levels in China’s mainland. The questionnaire is designed on the following four aspects toward strategic planning in public libraries: The attitude, the status quo, basic issues and the guides. The 882 valid questionnaires are processed by a statistic analysis to reflect the current practices of strategic planning in public libraries in China’s mainland.Findings: Our research results reveal that the unclear and confused understanding of the strategic planning still exist among the public libraries staff in China’s mainland. However, the majority of respondents still believe that the strategic planning in public libraries is significant and the library developments will be affected for lacking strategic planning. Moreover, it is considerable that the strategic plans are jointly made by independent agencies and public libraries, or by the public library itself. Also, guidelines and a set of softwares in strategic planning are needed.Research limitations/implications: The study was restricted to six main areas in China. A wider geographic sampling can preferable show the basic status of strategic planning in public libraries.The procedures of data collection would be another limitation. Nevertheless, case studies should be used in the further research.Originality: The importance of this research originates from a large number of first-hand data about strategic planning in public libraries in China’s mainland. The results provide extra perception into the future development of Chinese public libraries. The understanding obtained from this study will play a part in forthcoming evolution of this area of research.展开更多

During the period of the national Eighth Five-year Plan(1991—1995), the scientists with the CAS went on working at the frontiers of international science.According to statistics,there were 205 key R&D projects展开更多

Through digitalization of original analog video, locomotion characters of ants were obtained, the biomimetic foundation was laid for polynomial trajectory planning of multi-legged robots, which was deduced with mathematics method. In addition, five rules were concluded, which apply to hexapod robots marching locomotion planning. The first one is the fundamental strategy of multi-legged robots' leg trajectory planning. The second one helps to enhance the static and dynamic stability of multi-legged robots. The third one can improve the validity and feasibility of legs' falling points. The last two give criterions of multi-legged robots' toe trajectory figures and practical recommendatory constraints. These five rules give a good method for marching locomotion planning of multi-legged robots, and can be expended to turning planning and any other special locomotion.展开更多

After the enlargement of the production capacity of such plants, there will be the need of managing the new production level. That level is usually the industrial one, which poses challenges to the managerial staff. Such challenges come from the fact that several of those plants operate today on a laboratorial basis and do not carry inventory. The change to the industrial production pace asks for new actions regarding planning and control. The production process based on the hydrolysis of UF6 is not a frequent production route for nuclear fuel. Production planning and control of the industrial level of fuel production on that production route is a new field of studies. The approach of the paper consists in the creation of a mathematical linear model for minimization of costs. We also carried out a sensitivity analysis of the model. The results help in minimizing costs in different production schemes and show the need of inventory. The mathematical model is dynamic, so that it issues better results if performed monthly. The management team will therefore have a clearer view of the costs and of the new, necessary production and inventory levels.展开更多
