TSP (Traveling Salesman Problem) is the generalization and simplification of a variety of complex issues that arise in many areas, which is easy to describe but difficult to solve as an NP complete problem. Based on the TSP problem, we allow more than one vehicles to distribute goods in the transportation network, and each node in the network can be serviced by more than one vehicles. We build a more...
The Truck-and-Trailer Routing Problem (TTRP) is a variant of the Vehicle Routing Problem (VRP). The TTRP extends the basic VRP to take a real-life application into account. This study considers TTRP with time window constraints, and establishes a mathematical model. In addition, a two-stage hybrid algorithm is proposed to solve the problem. In the first stage, the rule of Nearest Neighborhood is applied...
In this article, a model is constructed based on MNL model (namely Multinomial Logit model) to study on the passenger flow sharing rate between Beijing-Guangzhou CRH (namely China Railway High-speed) sleeper train (referred to as “the train” hereinafter) and aviation. With orthogonal SP (namely Stated Preference) data and NLOGIT software, parameters of this model are calibrated. Aggregate analysis...
This paper mainly discusses the loading and routing problem of finished car logistics. Finished car logistics is a special commodity business which is produced accompany with the development of the whole vehicle economic. The logistics company loads up the finished cars in accordance with the customers' order, and arranges a suitable route to transport finished cars from manufacturer or distribution...
In the tractor-and-trailer transportation system, empty trailers always need to be dispatched insides owing to their same nature and uneven distribution of cargoes. Hence, they are also scheduling objects, as well as laden trailers. Compared with laden-trailer tasks whose origin and destination (OD) are clear, we can only know overall empty trailers' supply and demand, while specific OD are uncertain...
The extension class of the traditional vehicle routing problem, where there are several tasks in a goods transportation and goods are transported from one pickup point to many delivery points in each task, is studied in order to schedule vehicle routes with the lowest cost. A two-phase greedy strategy was put forward based on one to many pickup and delivery vehicle routing problem. The inner routing...
