Abstract: The invention relates to a CTC3.0-based locomotive decoupling and coupling plan automatic generation and execution method. According to the method, by upgrading a track occupancy display terminal and a data platform in a CTC3.0 system, automatic generation of a locomotive decoupling or coupling plan is triggered when the route display terminal receives a train plan, so as to complete a locomotive decoupling or coupling task. The method has the advantages of high automation degree and high transportation efficiency.

Abstract: The system receives a set of present time-series signals gathered from sensors in the asset. Next, the system uses an inferential model to generate estimated values for the set of present time-series signals, and performs a pairwise differencing operation between actual values and the estimated values for the set of present time-series signals to produce residuals. The system then performs a sequential probability ratio test (SPRT) on the residuals to produce SPRT alarms with associated tripping frequency (TF). While the TF exceeds a TF threshold, the system iteratively adjusts sensitivity parameters for the SPRT to reduce the TF, and performs the SPRT again on the residuals. The system then uses a logistic regression model to compute a risk index for the asset based on the TF. If the risk index exceeds a threshold, the system generates a notification indicating that the asset needs to be replaced.

Abstract: A method of agent allocation includes collecting historical service data of each of agents; performing classified counting of the collected historical service data of each of the agents, calculating agent skill values of each of the agents corresponding to the different user levels; counting the agent skill values of all agents corresponding to a same user level as an agent skill value group, successively determining agent queues corresponding to each of the user levels, labeling each of the determined agent queues with an agent queue skill level; determining a ranking of agent queue skill levels corresponding to each of the user levels, wherein in the ranking of agent queue skill levels, the agent queue skill level is a first agent queue skill level ranked at a first place; and finding an idle agent orderly in response to agent service requests transmitted by user terminals of different user levels.

Abstract: The disclosed embodiments relate to a system that facilitates deployment of utility repair crews to nodes in a utility network. During operation, the system determines a node criticality for each node in the utility network based on a network-reliability analysis, which considers interconnections among the nodes in the utility network. The system also determines a node failure probability for each node in the utility network based on historical weather data, historical node failure data and weather forecast information for the upcoming weather event. The system uses the determined node criticalities and the determined node failure probabilities to determine a deployment plan for deploying repair crews to nodes in the utility network in preparation for the upcoming weather event. The system then presents the deployment plan to a person who uses the deployment plan to deploy repair crews to be available to service nodes in the utility network.
