In accordance with the Hybrid multi-attribute decision making problem with attribute value of several interval uncertainty data information, decision making method is presented. First, the paper gives three interval type representations of attribute value, then, makes use of set pair, convert interval type attribute value into the presentation of connection number and construct the connection degree...
According properties of fractional Brownian motion, a precision rotor's radial rotating error have been analyzed. The results indicate that rotor's rotating motion is characterized by fractional Brownian motion, i.e. randomicity, nonsequencity, and self-simulation to some extents. Then fractal box counting dimension and Hurst index of radial rotating error have been calculated too. It can be deduced...
The evaluation of enterprise informatization is significant because the process can help us find the system defects. This paper's aim is to propose a dynamic analytical framework on enterprise informatization evaluation based on the stage characteristics of implementation. Firstly, it summarizes and compares the existing literatures on informatization evaluation methods and evaluation systems. Secondly,...
The role of small and medium enterprises (SMEs) has been crucial in developing countries' process of economic reform. Nevertheless, some bottlenecks and obstacles appear for further growth of SMEs, especially with respect to financing. SMEs use less formal finance than large firms in all countries, since they are younger and subject to more growth uncertainty than large firms, especially in developing...
In the hub-and-spoke clusters innovation systems, there are a number of system defects which affect the innovation behavior and performance. The evaluation of cluster innovation capability is significant because the process can help us find the system defects. This paper uses multilevel gray evaluation method to evaluate the innovation capability of hub-and-spoke enterprises clusters which combined...
