Patent number: 10157509Abstract: An incident management system in a public transit network receives incident data collected by one or more sensors of the transit network, segments a display screen into multiple cells so that each of the cells corresponds a route segment and a time segment in which one or more vehicles in the transit network traveled, and outputs a graphical representation for each cell. The sensors may be installed on a vehicle to detect various types of incidents such as disturbance, safety and mechanical issues, or any incidents external to the vehicle. The graphical representation may be indicative of the estimated future incident rate for the route segment and the time segment to which each cell corresponds, and displayed by a color scale in a heatmap. The system may estimate the incident rate using a linear model that can be obtained in a training process.Type: GrantFiled: December 28, 2016Date of Patent: December 18, 2018Assignee: Conduent Business Services, LLCInventors: Bryan R.

Publication number: 20160110653Abstract: A method, non-transitory computer readable medium, and apparatus for predicting a service call for digital printing equipment from a customer are disclosed. For example, the method detects a triggering event based upon a number of detections of an event on a digital printing equipment exceeding a threshold within a predefined time period, wherein the number of detected events on the digital printing equipment exceeding the threshold within the predefined time period is indicative of an impending soft failure, calculates a probability that the customer will place the service call due to the impending soft failure within a second predefined period of time based on a fusion of a hazard model of the digital printing equipment, a customer behavior model and the number of detections of the event in response to the triggering event being detected and determines an action based upon the probability using a cost based utility function.Type: ApplicationFiled: October 20, 2014Publication date: April 21, 2016Inventors: Diane Marie Foley, Juan Li, Bryan R.
