Development of low-carbon economy and low-carbon logistics is an important part of China's logistics in the long-term development plan. On the basis of the city logistics distribution which is an important part of the logistics system, this paper studies the optimization of distribution network in the city from the perspective of low carbon economy and researches on the two-echelon location-routing...
The physical Internet (PI) is a conceptual, innovative, and contemporary modular distribution logistics system that has garnered the interest of both researchers and practitioners as an alternative to conventional logistics. It aims to be more environmentally friendly, more socially responsible, and also more profitable. The key concept behind the PI logistics system is the routing of highly modular...
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...
Order picking is the most labor-intensive and costly activities in many warehouses by consuming ca. 60 % of the total operating expenses. Order picking development strategies mostly concentrate on warehouse layout, storage assignment policy, routing, zoning and on batching methods, while the physical parameters of the products - which are hardly ever taken into account - do also have a significant...
This paper takes vehicle distribution of TPL as the object of study, discussing the solution to the arrangement of vehicle routing problem which is based on “multi-deport” vehicle distribution of the triangle network. As for the actual situation of vehicle distribution, clusters the supply and demand nodes into sliced area in order to form triangle distribution model and realize the triangle closed-loop...
This paper presents a hierarchical model of logistics delivery networks by using some principles in graph theory. Based on the proposed hierarchical model, an optimal solution for dynamically configuring the resources of logistics delivery networks is devised through setting the appropriate value for the weight of edges in the model, which aims at minimizing the total traffic cost of a delivery network...
A new solution to vehicle routing problem (VRP) is proposed in order to overcome the disadvantages that the exact algorithms and heuristics algorithms are difficult to solve vehicle routing problem with multiple constraints. A simulation model of vehicle routing problem is built by combining the object-oriented technology and discrete event simulation technology. In this model, the events of distribution...
This paper discusses a new way to solve the vehicles routing problems of logistics distribution with the use of TSA (Tabu Search Algorithm). TSA is used to calculate the cost of the dealer or the company of all filiale, which is based on the actuality that there are distribution tasks among filiale (or distribution centers) in the cooperative distribution. A new way here is established considering...
