The rapid developments of the Internet of vehicles (IoV) technologies and big data technologies in recent years have offered new solutions to improve traffic safety and efficiency. In this paper, we propose a system architecture that aims to combine driver background data and driving data, in order to analyze and evaluate driving behaviors. To demonstrate the idea, we utilize logistic regression to...
The environment problem has aroused people's concern in recent years since the heavy haze weather. Agricultural products logistics, acting as one of the necessary activities to keep people's daily life and the main source of environmental pollution, receives widespread attention in the whole society. Basing on the field survey of agricultural products distribution system in Beijing, we clarify the...
This article describes an exact method based on a Branch & Cut algorithm for the multi-region vehicle routing problem in large quantities by a heterogeneous fleet of vehicles. Test results on different problem instances are presented after have been solved by CPLEX.
Building on a case study that we generalize, we use a model of interval four indexes transportation problem (4ITP: origin, destination, goods types, vehicle types) and find a solution on the minimum transportation cost for the distribution planning between manufacturers and customers. The 4ITP with real variables and deterministic parameters was solved for all cases where the problem is degenerated...
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...
The logistics network reliability theory is a probability index, which is more accurate to measure the status of the logistics network than absolute indicators. It can provide better decision-making basis for its planning and management. Therefore, study the reliability of logistics systems is essential to parts of the logistics business and even vital for the continued prosperity and stability of...
The Great East Japan Earthquake on March 11th, 2011 struck eastern coastal area of the Japanese main island and tsunami following the earthquake posed a devastated condition. Most of infrastructures and lifelines, such as water supply system, petroleum gas supply system and electric power system including Fukushima nuclear plant were damaged. Logistics system is no exception. All networks of highways,...
In this paper we consider the dynamic model of a logistic node of a transportation network. A necessary and sufficient condition for the existence of a stable feedback policy is given. Optimal dispatching rules can be derived in the case of small instances either by solving an integer programming problem or by considering a dynamic programming approach. Both methods present a combinatorial complexity...
The activities of route planning in logistics can be modeled according to the standard forms seen in vehicle route problems. This paper is devoted to the development of comprehensive fuzzy approach on variants of Vehicle Routing Problems when travel time is imprecise or incomplete. The problem of vehicle routing with fuzzy costs in the objective function and vehicle routing with time windows and fuzzy...
There is all kinds of risk consisting in every logistic distribution link of product oil because of the bigger product oil distribution district and the more complex distribution goods, a wide variety, quantity, and so on. Any question in a single spoken of earlier link happened will affect accuracy ,security and timeliness of indicator. This paper constructs evaluation index system and evaluation...
It is necessary to decompose a large map into small pieces while performing vehicle navigation path analysis in an onboard device. A principal component analysis based network decomposition is constructed to solve this problem. An index of connectivity is proposed in this method, by which the most correlative vertices relative to the destination vertices can be extracted from the complete road network...
For logistics providers, One of the most important strategic decisions to be taken in the design of logistic systems concerns the location of facilities (location problem). The other important strategic decision is the structure and management of the fleets (vehicle routing problem). Most often, even if the two kinds of problems, namely location of facilities and vehicle routing, appear together in...
This paper analyses the distribution modes selection of the regional food cold chain with the method of fuzzy evaluation, and uses AHP to ensure the weight of the index. At first, the paper analyses the mode of food cold chain and influence factors. Then it illustrates the problem of mode selection of the regional food cold chain, states the principle of index system of evaluation and steps to use...
