20140200827 | RAILWAY TRACK GEOMETRY DEFECT MODELING FOR PREDICTING DETERIORATION, DERAILMENT RISK, AND OPTIMAL REPAIR - Geo-defect repair modeling is provided. A method includes logically dividing a railroad network according to spatial and temporal dimensions with respect to historical data collected. The spatial dimensions include line segments of a specified length and the temporal dimensions include inspection run data for inspections performed for each of the line segments over a period of time. The method also includes creating a track deterioration model from the historical data, identifying geo-defects occurring at each inspection run from the track deterioration model, calculating a track deterioration condition from the track deterioration model by analyzing quantified changes in the geo-defects measured at each inspection run, and calculating a derailment risk based on track conditions determined from the inspection run data and the track deterioration condition. The method further includes determining a repair decision for each of the geo-defects based on the derailment risk and costs associated with previous comparable repairs. | 07-17-2014 |

20160026927 | BAYESIAN INTERACTIVE DECISION SUPPORT FOR MULTI-ATTRIBUTE PROBLEMS WITH EVEN SWAPS - A system, method, and/or computer program product that provides a first table including a plurality of alternative choices, each alternative choice including a plurality of attributes, and analyzes the first table to identify a set of alternatives of the plurality of alternative choices. The analyzing includes identifying alternatives that are practically dominated in accordance with a probability distribution over user preferences. The system, method, and/or computer program product may also recommend an even swap based on the probability distribution over the user preferences. Next, an input is solicited by displaying the set of alternatives. In response to receiving the input responsive to the displaying, zero or more of the plurality of alternative choices are removed from the table. | 01-28-2016 |

20160048126 | GENERATING WORK PRODUCT PLANS SPECIFYING PROPORTIONS OF CONSTITUENTS TO BE USED IN FORMING A WORK PRODUCT - A method includes receiving a given work product plan specifying a set of constituents to be used in forming a given work product, each constituent having one or more properties, the given work product being associated with a given class of work products. The method also includes obtaining information associated with one or more existing work product plans for one or more existing work products in the given class from a knowledge database and selecting proportions of the set of constituents to be used in forming the given work product based at least in part on distributions of characteristics associated with types of constituents used in forming existing work products in the given class and of properties of constituents used in forming existing work products in the given class. The method further includes generating an updated work product plan for the given work product specifying the selected proportions of the set of constituents to be used in forming the given work product. | 02-18-2016 |
20160048853 | GENERATING WORK PRODUCTS USING WORK PRODUCT METRICS AND PREDICTED CONSTITUENT AVAILABILITY - A method includes predicting availability of a plurality of constituents for one or more future epochs, obtaining one or more metrics for each of a plurality of existing work products, each of the plurality of existing work products using at least one constituent, and generating at least one work product for each of the one or more future epochs based in part on the predicted availability of the constituents and the one or more metrics for the existing work products. The metrics for the existing work products may include quality metrics and novelty metrics. | 02-18-2016 |
