Inference and prediction of routes have become interest over the past decade owing to a dramatic increase in package delivery ride-sharing services. Given underlying combinatorial structure incorporation probabilities, route involves techniques from both formal methods machine learning. One promising approach for predicting uses decision diagrams that are augmented with probability values. Howe...

The single vehicle routing problem with multiple routes is a variant of the vehicle routing problem where the vehicle can be dispatched to several routes during its workday to serve a number of customers. In this paper we propose a goal programming model for multi-objective single vehicle routing problem with time windows and multiple routes. To solve the model, we present a heuristic method wh...

According to the report of the United States transportation department, mechanical damage is one of the most important reasons for the pipeline accident .The most typical form of mechanical damage is indentation. Dent defect is one of the important factors affecting pipeline fatigue life, and it will greatly reduce the fatigue life of the pipeline in service. Meanwhile the dent displacement wil...
