In order to facilitate the selection of appropriate types of vehicles for target agricultural products, to enhance distribution efficiency, to cut down distribution costs, and to achieve scale economy in distribution, better utilizing both the value and use value of agricultural products, this thesis pays due attention to the features of integrated transportation of agricultural products and the differences...
This paper analyzes the logistics mode present situation of Erdos mining area, proposes the “delivery - to take coal” two-way transportation mode, designs the improved genetic algorithm for the problem, establishes the mines VRP - SDP problem mathematical model, uses MATLAB software programming and simulation run, obtains the optimal solution of the problem.
To ensure the security of the payment of Logistics vehicles, we design a specialized cash box based on GPS. The design combines GPS satellite positioning technology, GPRS communications technology, electronic locks and microcontrollers and other advanced technologies. This cash box on the logistics vehicle is characterized by opening designated locations, remote control, an alarm for abnormal state,...
The paper presents selected aspects of a single-depot vehicle routing problem with multi-commodity heterogeneous suppliers demand. Main attention is paid to the problem of certain goods groups transport on the same vehicle. To solve this problem each supplier is characterized by a different goods group which is in his possession. Also the structure and the characteristics of a goods transportation...
Flexsim software can model discrete-time system; it is an ideal choice to plan the distribution center simulation and logistics system. The paper is according to the Flexsim system simulation software, comparative analyzing the distinguish of different picking strategy of distribution center, qualitative analyzing many types of applicability and relative merits of picking strategies, discussing the...
The role of travel behavior of private cars in the vehicle routing schemes in city logistics distribution is investigated in this paper. A mixed logit model has been established to account for the influence of travel behavior to logistics distribution. A numerical study is conducted to understand the influence of the vehicle routing schemes in city logistics distribution.
This paper presents a method of allocation transportation services costs to the carrier's clients. Method is based on determining replacement costs for two cost-driven elements: amount of pallet-kilometers and time consumed for services realization in purpose of using it to weight real costs for finding actual share of clients in total costs.
Logistics costing provides useful information for decision makers when planning or evaluating logistics services and functions. The traditional procedures applied for calculating logistics costs are, however, not always able to deliver the requested information due to the use of arbitrary allocation techniques. This paper introduces a calculation approach for logistics with more exact cost allocations...
In the logistics industry, according to the different tasks and reasonable transport vehicle scheduling, is to save transportation costs and increase economic benefits must be considered. This task needs to start talking, analysis of the features and characteristics of VRP, how to improve the basic ant colony algorithm, will be introduced and used to solve the VRP problem. According to the characteristics...
In the emergency response system of public events, emergency evacuation of the road choice is the important part. Based on the characteristics of emergency logistics, analysis of its target, difference and constraint conditions, summary relief supplies under emergency transport restrictions. Design of relief supplies, and reliable transportation and vehicle routing scheduling model. In this way the...
We introduce a Multi-Point Stochastic Insertion Cost Gradient Descent (MuPSICGD) heuristic algorithm to solve multi-depot split-delivery vehicle routing problem (MDSD-VRP) through an innovative approach. We also describe two solution improvement techniques that can further enhance a fairly good solution. Our contribution is threefold: First we present a heuristic-based mechanism to solve multi-depot,...
The literature on the Distance Constrained Vehicle Routing Problem (DVRP), which is an important extension of the classical Vehicle Routing Problem (VRP), is scarce. In this paper, two new arc based integer programming formulations, with polynomial size are presented. It is shown that, second formulation, designated as strengthened model produces stronger lower bound than the first and existing arc...
So many problems all need realize food logistics' traceability of change, such as the effective improvement of food quality, the effective supervision of food corporations, the effective increase in consumers' purchase confidence. This paper presents and analyses the food-cold chain logistics' traceability technology, constitutes food-cold chain logistics' tracing system model, proceeds to the function...
The coal industry is the most important economic pillar in Shanxi province, China. As an important part in the coal industry, while it promoted the rapid development of the economy in Shanxi, but also a lot of negative impact on the environment in Shanxi. This paper based on the theory of green logistics, and proposed analysis and evaluation of the status quo of the Shanxi coal logistics.
The vehicle routing problem in the electronic commerce environment pays more attention to the time management. This paper established a general mathematical model with the soft time windows in the e-commerce environment. In the process of research, adopted the simulated annealing algorithm for solving it, and analyzed the effect of solutions caused by different importance of distance and time cost...
Distribution, which is one of important part in the logistics system, has a great influence on the improvement of the whole logistics efficiency and reducing of cost. Nowadays, because the development of domestic logistics distribution is still at initial stage and distribution scheduling system is basically at artificial experience stage, it is unable to meet extensive centralized distribution, uniform...
Through the study of the Internet of Things technology, the idea combining EPC Internet of Things with WSN is proposed which demonstrates the integration feasibility of the RFID and WSN technology. In order to improve the efficiency of logistics enterprises all aspects in the transport process should be monitored which need to apply the Internet of Things technology into the logistics management system...
On Based on the static vehicle routing problems and actual practices, this paper transforms the constants from the static model into dynamic, and deduces the model of dynamic vehicle routing problem, moreover, designs a model algorithm. According to the analysis, the model can be in line with actual needs and easy to solve in practical problems.
The F-35 “Lightning II” Joint Strike Fighter (JSF) Program is developing a comprehensive and industry-leading Prognostics and Health Management (PHM) system. This system, which is central to the program's Performance Based Logistics (PBL) approach, is built on incremental capability deployment and a careful balance of on-aircraft and off-board software, systems, and processes. The breadth of capability...
