Foreign logistics enterprises use information technology and rapid reactive operation to subordinate Chinese logistics market, the logistics information technology level of our countries' enterprises increased year by year, and informationization level is also higher and higher. As the internet of things technology development, the logistics information management achieved by the internet of things...
Ant colony algorithm is a kind of novel simulation-biological evolution algorithm. An improved ant colony algorithm was utilized to solve the vehicle routing problem in emergency logistics. Genetic algorithm was utilized to optimize the parameters of ant colony algorithm. The algorithm possesses some characteristics such as strong total researching ability. The experimental results show that the improved...
Overloaded vehicles may cause excessive wearing and damages to pavements, roads and bridges. They also threaten the road safety and contribute to several fatal accidents, thus the governments around the world have implemented axle load limitations. This paper investigates the overloading level at the southern part of North-South Expressway in Malaysia. The data were gathered from three survey stations...
Freight movement by truck is the common mode in freight distribution due to its flexibility and cheap prices. However, the importance of freight movement by trucks is often not fully understood. This paper thus seeks examines the factors threatening freight movement by trucks that influence the delivery effectiveness. The prescription in this paper is based on the syntheses of critical analyses of...
The planning of a good logistics village is very significant for the new era of logistics industry, it play a major role in the transportation and distribution of goods effectively. Efforts were put to understand the characteristics of a comprehensive logistics village planning by referring to Malaysia Environment. Result from the analysis showed that there are differences in planning a logistics...
This paper presents the design of an automatic target classifier for a Ground Surveillance Radar namely NUST Radar∗ (NR-V3). The classifier is developed to distinguish between pedestrians, vehicles and no target (noise) classes. Feature vectors are extracted from the FFT spectrum of radar audio signal. Logistic regression and linear discriminant analysis based classifiers are used for classification...
The military tactical logistics planning problem addresses the issue of distributing heterogeneous commodities in a theater of operations using a combination of heterogeneous transportation assets such as logistics trucks and tactical helicopters. The Canadian Forces requires a decision support tool to examine the trade-off between the cost of the support and its effectiveness during sustainment operations...
Traffic jams is a crucial factor that affect logistics costs and transportation time, therefore, this paper give the improved ant colony algorithm strategy in selection next node, comprehensive the length of the road and block coefficient when calculate, so that take into account the actual path length and time costs during transport. The results show that the improved ant colony algorithm has a better...
This paper presents an innovative modeling framework able to support planning, management and optimization of waste collection operations in an urban context. A proprietary simulator composed by three functionality modules (Global Positioning System, Data Mining system, Simulator for routing and resource exploitation) was implemented by the authors, and was then validated on a specific set of case...
Vehicle routing problem has been largely studied because of its application in logistic and supply chains management. A number of algorithms inspired by the foraging behaviors of ant colonies have recently been applied to solve vehicle routing problem and its variants. The behavior of ant colonies algorithms depends strongly on the values given to parameters. In most applications, parameter values...
Logistics distribution supports the economy development in urban agglomeration. This paper analyses the factors impacted on vehicle routing schemes in distribution of urban agglomeration in a new point of view. The alternative routes which are prepared for private car drivers to choice are generated based on anticipation regret. The method which was presented in this paper is approved to be more accord...
Road transport is one of the most important parts of logistics carry. In order to improve efficiency and quality of logistics carry, It is required that diagnose and maintain remote trouble carry vehicle rapidly. This paper researched the Remote fault Maintenance Support System of Logistics carry Vehicle based on network. Some techniques including embedded computer, wireless communication, network...
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...
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...

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.
