As an innovative e-commerce model, mobile business will definitely turn into an alluring industry in the near future. By using the statistics of the accumulative cellphone-on-line surfing netizen and the nonlinear least squares method which is offered by the ldquoSPSSrdquo software, the authors of this paper try to estimate the critical parameters in the ldquoBASSrdquo diffusion model and thus make...
An operation model is proposed in this paper for an electronic market enabled supply chain with uncertain variable costs. The supply chain consists of multi-supplier and multi-customer, suppliers can provide many kinds of product to different customers directly or through electronic market. Uncertain variable costs are described as symmetrical and limited intervals. A robust operation model for this...
We propose and study an evolving network model for instant messaging system (IMS) with local-world preferential connections and acquaintance introduction mechanisms, which exist in many physical complex networks especially in IMS evolving network. We put forward the algorithms to generate IMS evolving network model and through simulation results we talk about the topological properties of the IMS...
This paper proposes a service selection solution named ZX, which is based on the selector-side QoS measuring results. In ZX, we identify the QoS attributes which could be measured in selector's side, and provide possible solutions to gather the QoS information, and we introduce a new service selecting method, which concerns normal-the-better QoS attributes, by implementing the nearest neighbor algorithm.
Trading behaviors in a game between buyers and sellers in E-Commerce market are not only a stochastic process, but also reflect the equilibrium of the existence and consistency. Based on newsvendor model, the structure of information asymmetry commodity trading market is designed and constructed. According to transferring value of information attributes, two definitions of equilibrium in two stages...
Network teaching resource evaluation is the process of evaluating complex information systems according to multi-level. In order to raise the objectivity and accuracy of the evaluation, an evaluation method based on rough set theory is proposed, the principle and basic procedure of evaluation by this method are described in detail. Finally, we give an example to illustrate its application.
This paper addresses the problem of learning optimal classifiers that maximally improve the robustness and accuracy in uncertain environment included a large number of noise and missing values. Recent solutions to the efficiently vertex weight evaluation, such as the Bayes Network, rely on statistics methods, without sufficient robust guarantees. We show how a globally optimal solution can be obtained...
Building an effective trust transaction management mechanism is an important way to prevent fraud behavior in m-commerce. Based on analyzing limitations of the existing online trust transaction mechanism, and according to characteristics of m-commerce transaction trust problem and business coalition in traditional commerce field, the article proposes a new trust transaction management mechanism on...
In order to solve single operation mode, weak profitability and low customer loyalty problems of the learning website, some improvement strategies based on value chain model analysis are put forward in the paper. Value chain analysis is an effective tool to research the enterprisepsilas competitiveness. By studying value chain, the method to improve the competitiveness of the learning website can...
In resent years, there have been significant changes in Chinapsilas telecom VAS industrial chain. The telecom operators have been taking steps to develop their own VASs and bypass the independent VAS providers. This article analyzed the reasons and motivation of telecom operatorspsila vertical expansion from the perspectives of neoclassical economics, new institutional economics and enterprise competence...
E-commerce is essentially based on trust. The level of enterprise Website credibility is an important basis for the Website browsers (or consumers) deciding whether to take further action or not, and will have a great influence on their purchase decision-making. This paper firstly defines the meaning of the enterprise Website credibility. Secondly, it divides the enterprise Website credibility into...
Recently, the frequency of natural disasters is increasing sharply, especially the seismic activities which have been reached to a new peak, such as WenChuan earthquake in China, LpsilaAquila earthquake in Italy. The disasters not only cause immeasurable casualties and infrastructures damage, but information and data losses, which will bring big troubles to the post-disaster reconstruction projects,...
The present paper presents an economic order quantity model for the inventory of a deteriorating item with demand rate as a ramp type function of time, in which the inventory is permitted to start with shortages and end without shortages. A two-parameter Weibull distribution is used to represent the distribution of the time to deterioration. A theory is developed to find the optimal solution of the...
In order to achieve high performance of grid computing, an efficient resource allocation protocol needs to be carefully chosen and applied. Using auction mechanism design theory, this paper designs a novel double auction mechanism which is appropriate for allocation of multi-unit homogenous and divisible resources in the grid. In the grid, there are multiple resource consumers and resource providers...
In order to provide a transaction environment of more security for e-commerce system, a novel intrusion detection system (IDS) based on the system call sequences is proposed in this paper. Firstly, this system improves the basic short sequence matching model combined with consistency principle of process initialization to emphasize on detecting system call sequences when process is initializing. Secondly,...
