Agriculture has a variety of functions. City green space can be viewed as the agricultural ecological function. The flourishing of the urban green space is the inevitable result of the urban development. For the practical and the need of the urban green space development, this paper discuss how to build the least street parks at the junctions to meet the demand of residents by using the coverage set...
The application of the neural network in the structure damage identification is studied using a combination of theoretical and experimental methods. A multi-layer neural network models based on the BP algorithm is designed for the damage identification of existing model structure. The model is trained with the data from an engineering beam to filter different transfer function, train function and...
This paper established a two-stage logic trust model for consumers with online shopping experience and without, and on this base, put forward the corresponding calculation formula and assessment method of trust degree, which provide reference and experience for the e-business companies to make correct decision and reasonably schedule their network marketing activities due to different stages of consumers.
Presently, China coal mine enterprises are under merger and reorganization great environment. These enterprises merger and acquisition (M&A) process efficiency predictions lack theoretical support. The paper constructed coal enterprises M&A efficiency evaluation system, built the M&A efficiency prediction model based on support vector machine (SVM). The paper investigated the data in 2004-2008...
It is widely regarded that evaluation is a complex systematic project, which involving many aspects of the process in technological innovation, epically for the pharmaceutical sector. Based on 18 original-designing indicators and the Factor analysis, the paper evaluates the stage differences of continuous innovation abilities in Chinese hinterland provinces' biotechnology industry. And then it originally...
In software projects, program evaluation and review technique (PERT) is frequently used to estimate the schedule of the uncertain projects. However, classic PERT does not allow the existence of loop in PERT graph, and assuming that all the activities time subject to the probability distribution. All these restrict the use of PERT. Firstly, by mapping PERT network to the Petri nets based model, this...
