If ubiquitous learning is to be effectively developed and feasibly applied to education, it is necessary to evaluate its effectiveness. Using fuzzy theory, the ubiquitous learning evaluation model is established in the paper. Evaluation index system is formulated which accords with ubiquitous learning and learners characteristics. Put forward subjective and objective weighting method to determine...
According to the application practice of production and management in coal enterprises and the basic principles of establishing the evaluation index system of informationization, we designed the tentative evaluation index system of coal enterprise informationization first; and then we selected the indices and optimized the index system by using the principal component analysis method, establishing...
In order to grasp the states of human resource management accurately, this paper studies the whole process of human resource management from the input to the output of human resource, establishes the evaluation index system of human resource crisis, and evaluates the human resource management crisis of the enterprise with principal component analysis. This paper draws the following conclusions: the...
Agricultural leading enterprise is the one which provides services to peasants and promotes the development of commodity production, the implementation of agricultural construction is the key to rapid economic development. Fostering the growth of these enterprises and enhancing their competitive strength, is the effective measures to speed up construction of modern agriculture and the prosperity of...
Regional S&T popularization capacity building has not obtained our social attention and a complete evaluate quota system has not been instituted. Therefore, it is necessary to set up a scientific, simple but practical, combined the index system of the quantitative and qualitative evaluation. The text will define the conception of the regional S&T popularization capacity, institute the evaluation...
The paper aims at disclosing the process and steps of the relatively important index extraction by means of PCA, on the basis of analyzing the principle and theory of PCA and its application in the establishment of evaluation index system on the contribution of infrastructure construction to the coordinated urban-rural development. And the paper may function as reference source for the establishment...
Aiming to construct a hub-and-spoke logistics network for Zhejiang Province in China, a framework of hub-and-spoke logistics network construction was presented. In this framework, an evaluation index system was established according to the urban logistics development level, and based on principal component analysis, 33 cities in Zhejiang Province were classified, taking Hangzhou, Ningbo, Wenzhou as...
Urban economic development Capacity refers to the development strength and potential that a city reveals while taking advantage of its own resources and conditions to compete with the other cities in economic development. Being the central city of the economic zone in the southwest area of Shandong Province and linked up with Huaihai Economic zone, Jining plays an important role in setting up the...
With the development and reformation of China's power market, the environment of production and management is changing fundamentally. Therefore, considering the risk character of power supply enterprises, an evaluation index system to evaluate the risk in power supply enterprises is established. Then by combining PCA (principal component analysis) and BP neural network together, a risk evaluation...
In order to accommodate the demand of electricity market and do effective evaluation, we establish the index system of evaluation, and the model based on support vector machine (SVM).The synthetic evaluation of electricity target markets in B region, proves the model is feasible and effective, shows this method can improve the evaluation precision and has good spread ability.
