The dynamic evolution mechanism of urban consumption structure upgrading is studied based on the construction and application of variable parameters extended linear expenditure system (TVP-ELES model). The growth effect of consumption structure upgrade is measured based on the theory of “demand creation”. The research results show that consumption structure elements such as the basic needs coefficient...
Communication networks are large distributed systems designed to send messages from one location to another. Messages are generated by a source and transmitted through a server to their destinations. Servers are connected by the transmission links through which the data flows, and each server has a certain queue capacity. When the number of incoming messages exceeds the capacity of the server or the...
Nowadays there is the requirement for the selective protection technology of the MCCB used in the DC power system. To achieve this goal it is necessary to improve the short-time current withstand performance of the MCCB. However, the experimental test on such a performance is quite time consuming. Therefore, it is very important to evaluate the short-time current withstand performance of the MCCB...
To improve the quality of logistics service is considered to be the preferred method to hold the customer. From the sight of Systemism, project logistics service is a complicated systems engineering with non-repeatability, systemic, risk, planned, high performance technologies and other features. For such a complex system, we need to build simulation model from system structure to refinement the overall...
Electronic money products have advanced quickly with the rapid growth of electronic commerce, and different stakeholders show shared concern on the related impact. In order to have a holistic and in-depth analysis of the e-money issues, this paper studies the e-money dynamics from complex system perspective. System complexity analysis is conducted and a four-phase modeling approach is proposed. This...
In e-commerce environments, problems of credit risks are more serious than that of the traditional commerce due to interactions between unfamiliar peers. The application of credit evaluation system for e-commerce plays a important role in mitigating credit risks. This paper proposes an improved AHP-based multi-dimension credit evaluation model based on an analysis of the drawbacks of the current model,...
