This has also triggered a series of frontier issues. This requires our frontier government to strengthen border governance, seize the opportunity to meet challenges, and at the same time we must also strengthen the assessment of the governance capacity of the frontier government. This article hopes that through the actual investigation and study of frontier counties and the consideration of border issues according to local conditions, a set of performance evaluation index system for frontier county-level governments will be proposed, which will help the frontier government in border control.展开更多

With the performance evaluation theory,the performance evaluation model of waste collection and transportation system was constructed,which quantified the grading standard of index and determined the index weight in analytic hierarchy process (AHP). After evaluating the waste collection and transportation system of the main districts of Chongqing city,the results show that the it has an excellent performance evaluation grade with very high performance level of three indices involving evaluation of management and society,environmental impact assessment,evaluation of security and emergency and quite low performance level of two indices that include high efficient evaluation and economic evaluation.展开更多

In 2015, the pilot city of sponge city's construction has begun to take shape with the push of the Ministry of Housing and Urban-Rural Development of the Peoples' Republic of China, the Ministry of Finance and the Ministry of Water Resources. For the pilot cities, they should strengthen the performance evaluation process and play the leading role of the nation demonstration. Taking the aspects of sponge city project's management, runoff volume control into consideration, sponge city initially formed a set of scientific and objective evaluation index which is in order to reflect the effectiveness of Gui-An New Area's construction.What's more, through analyzing the sponge city's deficiency of the performance evaluation, I also carry out the work that need to put forward suggestions.展开更多

In this index system, we develop an expert system to evaluate the performance of such multimedia communication networks including channel utilization and call blocking probability and packet delay, and apply the network planning methods to optimize the networks and forecast the demand of the growing multimedia communications systems. Two important planning problems for the multimedia communication systems are presented: optimization problem for construction of the world system and forecast problem for increasing traffic demands. We first discuss analysis methods, performance measures for the multimedia communication systems. Then, we describe network planning methods for the multimedia communication systems and give some efficiency network planning methods. Finally, we present some results studied in traffic forecast for the campus network and show the effectiveness of these methods.展开更多

The index is compatible with the non-linear static analysis (e. g. the pushover analysis), and the structural damage is considered via plastic hinges. Simultaneously, a practical approach is developed to obtain the relationships between the proposed index and earthquake intensities based on the capacity spectrum method. The proposed index is then illustrated through two low-rise reinforced concrete frames, and it is also compared with some other indices. The results indicate that the proposed index is on the safe side and not sensitive to the lateral load pattern. The storey index is helpful to reflect the storey damage and to uncover the position of the weak storey. Finally, the relationship between performance levels and damage index values is also proposed through statistical analysis for the performance-based seismic evaluation.展开更多
