In this paper we define a concept of weak equilibrium for vector network equilibrium problems. We obtain sufficient conditions of weak equilibrium points and establish relation with vector network equilibrium problems and vector variational inequalities.
This paper is based on four in-depth case studies on the information and communication technology (ICT) evolution of Chinese tobacco companies. The ICT transformation processes of these companies are introduced briefly. A strategic grid model was used, which shows that depending on a company's strategic grid cell, different behavior patterns can be observed, in terms of Nolan's stage model. The analysis shows that companies allocated in the "turnaround" and "strategic" cell do not behave accordingly to Nolan's stage model. A few years after China first application for a World Trade Organization (WTO) membership renewal in 1986, observed companies skipped some of Nolan's stages to achieve an accelerated ICT transformation. Therefore, a fast transformation of ICT plays a major role for Chinese tobacco companies to face the challenges entailed by an open door policy and the WTO entry. This conclusion is limited to companies that are allocated either in the "transformation" cell or the "strategic" cell.
E-business success factors are Important for traditional enterprises to implement e-business. This topic is attracting more and more researchers to study. This paper makes an exploratory study on the factors influencing e-business success. Firstly, based on the literature review, 52 factors are suggested. Secondly, two rounds of survey with Delphi method are conducted. Qualitative and quantitative analysis are used to identify 57 factors. This is the foundation of empirical study.

The aim of this paper is to develop an ordered weighted distance(OWD) measure,which is the generalization of some widely used distance measures,including the normalized Hamming distance, the normalized Euclidean distance,the normalized geometric distance,the max distance,the median distance and the min distance,etc.Moreover,the ordered weighted averaging operator,the generalized ordered weighted aggregation operator,the ordered weighted geometric operator,the averaging operator,the geometric mean operator,the ordered weighted square root operator,the square root operator,the max operator,the median operator and the min operator are also the special cases of the OWD measure.Some methods depending on the input arguments are given to determine the weights associated with the OWD measure.The prominent characteristic of the OWD measure is that it can relieve(or intensify) the influence of unduly large or unduly small deviations on the aggregation results by assigning them low(or high) weights.This desirable characteristic makes the OWD measure very suitable to be used in many actual fields,including group decision making,medical diagnosis, data mining,and pattern recognition,etc.Finally,based on the OWD measure,we develop a group decision making approach,and illustrate it with a numerical example.
