This paper use the concept of matter-element and correlation function to establish a prediction model based on the extension of the cluster, and apply the model to forecast the wastewater emissions. Applied results show that this method is scientific and reliable.
It is not easy to entirely avoid the uncertainty of supply problem. To solve the problem relays on setting up some necessary safety stocks. Safety stock is an effective management tool for protecting the enterprises against the uncertainty and it provides customers with the promised service level, but a higher safety stock level does increase the supply chain operating cost. Determination of safety...
There are three parts of Digital Educational Resource Platform - Educational Resource, Support system and Learning Environment. The design strategy of Digital Educational Resource Platforms in University is making cleanly what the users need, integrating standardize, efficient architectures, open Stand-point. The procedure of designing the Digital Educational Resource Platforms is analyzing and designing...
With the development of uncertain theory, fuzzy multi attribute decision making has been applicated in more and more areas. This paper established optimization model based on fuzzy ideal points for uncertain multi-attribute decision making problem in which the attribute values are given in the forms of triangular fuzzy number and the information on attribute weights is unknown completely or partly...
To supply chain network design problems with considering E-commerce of scale and further demand fluctuations, a reliability evaluation method is developed to evaluate the performance of plants under demand fluctuations. In addition, a mathematical programming model is developed to determine the optimal adjustment decisions regarding production reallocation among plants under different fluctuating...
To solve security problems of E-commerce system, this paper proposed a new trust model APR which is based on anticipative perceived risk. The concept of perceived risk was introduced into APR, many kinds of trust factor were taken to calculate the trust value among nodes, and an origination method was provided to integrate direct trust and recommendation trust. Comparing with other trust models, APR...
Statistical models in which both fixed and random effects enter nonlinearly are becoming increasingly popular. These models have a wide variety of applications in many areas such as agriculture, forestry, biology, ecology, biomedicine, sociology, economics, pharmacokinetics, and other areas. Mixed effect models are flexible models to analyze grouped data including longitudinal data, repeated measures...
This paper studies the realizing progress of data mining in psychological evaluation. Based on the matrix of evaluation data and the actual evaluation work, we propose a kind of generalized linear regression model with convex constraint, named as evaluation model, in which the dependent variable and regression coefficients all are unknown. We analyze the algorithm of the model with linear regression...
It??s very significative to get the numerical prediction of the biomechanical response of eyeball to increased IOP. In this study, a geometry model of eyeball with 3-layers wall and optic nerve was built firstly; then, meshing and physical property was applied on it to get physical model; finally, the increase of IOP was simulated on it. The results of simulation experiment validate this model and...
Spatial information service plays an important role in E-Government, but different models differ most in various applications of decision-making support activities. Therefore, how to evaluate the applicability of spatial application model is the key problem for the usage of spatial models in E-Government application. In this paper an evaluating model has been proposed to solve this problem. Based...
