This paper quantifies the effect of “word-of-mouth” marketing strategy on pricing decisions in a competing duopoly market. Assuming that consumer arrivals follow a Poisson Process, a consumer's purchasing decision depends on his individual judgment and probability of his friends' existing selections, who connect to him in a ‘scale-free’ social network. Firms then make pricing decisions responding...
Value-added tax revenue occupies an important position in China. The efficiency study of value-added tax has important practical significance in the critical point of Chinese value-added tax transformation. Using BCC model we estimate Chinese value-added tax comprehensive efficiency, pure technical efficiency and scale efficiency from 1995 to 2008 from a macro perspective. The study shows that value-added...
The credit scoring has been regarded as a critical topic and its related departments make efforts to collect huge amount of data to avoid wrong decision. An effective classificatory model will objectively help managers instead of intuitive experience. This study proposes five approaches combining with the back-propagation neural network (BPN) classifier for features selection that retains sufficient...
In this paper, the author has discussed the optimum industrial cooperation problem in the background of multilateral regional cooperation. The problem of the optimum industrial cooperation has been converted into a mixed-integer linear programming model by the author who has synthesized the influence of the following factors: the connection between the cooperation industry and other industry, the...
In this paper, the author proposed the concept of incomplete and fuzzy information systems based on incomplete approximation spaces and fuzzy sets, and analyzed the approximate class-precision and boundary in rough set systemically, via introducing the thought of inner & outer boundaries and inner & outer approximate definable sets combining rough set with fuzzy set, variable precision theory,...

The development of soldier system is customarily based on intuition and experience, however, the costs of this process without simulation is quite high. For this, the soldier simulation system should be established. Based on the multi-body dynamics principle, the definition of dynamic virtual prototype (DVP) of soldier system is presented. The topological structure of soldier system is constructed...
