So far, two-sided markets theory is one of the latest hot and frontier in the research of the international industrial organization theory. In this paper, under the condition of inter-group externalities and intra-group externalities in the two-sided market pricing model, we will be researching for the impacts on the basis of inter-group externalities and intra-group externalities in the two-sided...
This paper analyzed the basic characteristics of online trading as a form of virtual enterprise under network environment, and the shell model was proposed, in which management behavior problems about online shop was discussed. Some developmental strategies about online shop were given at the end, which as a method for the management problems of virtual enterprise.
This paper presents a study on the mechanism of electronic emission by constructing electronic spread launching model and solving Poisson equation analytically between two planar plane. The results show that electron beam introduces periodic and non-periodic perturbation to primary vacuum potential. The overall effect of periodic perturbation can be ignored because of symmetry but non-periodic perturbation...
The trust management mechanism based on seller coalition and consumer virtual community is discussed in this paper, which is verified valid by game theory. The seller tends to carry out an honest transaction because of the increased opportunity cost in the mechanism, and consumers feedback transaction information positively because of the identity of community and the pursuit of interests, which makes...
UML Sequence Diagram (SD) is used to modeling the dynamic behaviors of system, but it lacks simulation and verifiability capabilities because of its semi-formal nature. This paper proposes a UML-CPN transformation method to building dynamic model in UML using CPN. This work aims to develop efficient transformation methods, and then uses CPN models to simulate, verify and evaluate the systems. This...
In order to ensure the correctness and reliability of Web services composition based on OWL-S, verify the interaction protocol of Web services. It is provided that three lay architecture. Composition service based on OWL-S, GA model is the middle model and the Promela model is the verification model, SPIN as a model validator. The OWL-S composition Web services transform a top-down conversation protocol...
