Despite the rapid growth of social commerce, there is only a limited understanding of how social media technologies, marketers and customers can interact to achieve business initiatives and opportunities. This study develops an integrative formative model outlining key qualities and dimensions of social commerce and their interactions. The model was validated with a field survey of 1250 social commerce...
The paper presented the fundamental of HHT and Fourier transformation through elaborating the theory and simulation experiments on matlab. Giving specific signal, the two transformations were used in application of partial discharge, voltage dip, and harmonic wave. Visualized spectrogram were obtained to compare the two transformations from each other, therefore, HHT and Fourier transformation can...
The existing methods to evaluate reliability of phased mission system with multi-mode failures are all very complex. In order to solve this problem, a simulation model based on CPN is proposed in this paper. Firstly, A CPN model of components with multi-mode failures is proposed; secondly, the CPN models to deal with dependencies are presented. On this basis, the phase reliability CPN model and mission...
Based on the analysis of the inadequacies of existing credit evaluation model for E-commerce in automobile spare parts industry, a credit evaluation system applying for E-commerce transactions is given and key factors affecting the credit of E-commerce transactions are extracted in this paper. The author proposes the calculation methods of static indicators score, dynamic indicators score in different...
Based on the analysis of the inadequacies of existing credit evaluation model for e-commerce, a multi-dimensional transactions credit evaluation system applying for e-commerce is given and key factors affecting the credit of e-commerce transactions are extracted in this paper. The author proposes three methods for the calculation of transactions credit. They're static integration calculation, dynamic...
It is very important to optimize the spare parts in conventional submarine to complete the mission. A new research methodology is put forward after summarizing the shortcomings of current study. For instance, the conventional submarine mission is modeled and simulated by colored Petri nets (CPN) to obtain the success oriented mission profile. Then the hierarchical simulation model of spare parts is...
The traditional FMEA method cannot describe the complex system clearly nor serve well for design of system when face to complex system. Aim at these questions, the FMEA method based on functional modeling has been put forward and given its process of analyzing. Take some warship voyaging system for example, analyzing the complex system by FMEA method based on functional modeling and validating the...
