Non-standard warehouse receipt pledge credit is a common and basic service form of supply chain financial products. This paper attempts to realize formalization and visualization description for such products. Petri net is used to model the business process of this service, and a hierarchical business model is built with the idea of modularization. Based on model correctness and performance analysis,...
Traditional deterministic methods usually applied to the most severe and low probability events in power system risk assessment, computation results are therefore much conservative accordingly. Considering both probability and their impact of the effects, risk assessment methods can provide comprehensive effect on the whole power system. The status quo related to risk assessment is reviewed. The meaning...
Zhang dynamics (ZD) and gradient dynamics (GD) are both powerful methods. Based on a pendulum system, this paper investigates both of the explicit and implicit tracking control using the ZD method. For solving the singularity-containing implicit tracking problems, this paper overcomes the singularities by using the ZD method in combination with the GD method (i.e., the ZG method). Analyses and simulations...
Social channel is the main component of telecom operators' marketing channel. Channel loyalty has become an important issue of telecom operators' channel management, with especially significant research and practical value under the environment that competition increases and services homogenates seriously among three full-service telecom operators. In order to study the connotation of channel loyalty,...
Data have been accumulated to wait for being analyzed in real world. But the imperfection of data complicates the analysis process. According to “garbage in, garbage out”, model built on such data will mislead the following study. Multiple empirical studies have showed that noise in dataset dramatically decrease the classification accuracy and increase the complexity of classification. Therefore,...
The nature of voltage collapse is that as power transfers into a well-bounded region are increased, the voltage profile of that region will become lower and lower until a point of collapse is reached. Continuation power flow (CPF) is a powerful analytical methodology and tool in static voltage stability analysis. Engineer may use P-V method for general voltage stability evaluation, contingency screening,...
