Based on the DEA (Data Envelopment Analysis) traditional model, an improved evaluation model is introduced for the fuzzy index value and fuzzy preference weight information. The improved model is applied in evaluation of automatic testing software programs. Firstly, the subjective index values are transformed into fuzzy numbers. Secondly, the subjective preference weights are constructed as a constrain...
Surface roughness is the most important index to evaluate micro-milling process. Surface roughness of the machined parts in the micro-milling process is mainly influenced by four cutting parameters (namely extended length of the micro-milling cutter, spindle speed, feed per tooth and cutting depth in the axial direction). The influence degree of the four parameters on surface roughness is not the...
In recent years, with the development of freeway in China, requirement of road users is increasing and construction mechanization degree is enhanced, asphalt pavement structure has been generally used for freeway, but how to design the asphalt pavement construction is the key problem that to ensure pavement performance. Asphalt pavement has appeared more or less premature failure in each province...
According to technological innovation in the economic and development zone, the article has established an index system to analyze and evaluate the ability of technological innovation in the development zone. Using grey systems theory and coefficient variation method, the article has proposed a synthetic evaluation method of grey incidence. Through analyzing the ability for technological innovation...
Value creation is considered as key to collaborative relationships. Though the body of literature in the area of relationship value is growing fast, most research is of conceptual nature including definition and construct. As long as measuring relationship value remains scarce, it will be criticized for its operational ambiguity. The relationship value incorporates both economic and non economic value...
Since the management is taken as an independent scientific theory to research, the theory of division of labor becomes the cornerstone of management science. It defines the role and focuses of management and leads the direction of enterprise management. However, the enterprises face ever more intense competition among enterprises. The management thinking which is based on the division of labor has...
In the recent years, as the development of automatic target recognition (ATR) technology, the performance evaluation for it becomes more and more important. In order to solve the problems of needing artificial intervene and needing too many samples in the existent evaluation methods, we proposed a new performance evaluation method for ATR system based on the backward cloud. In this method, we use...
