Engineering collective adaptive systems (CAS) is a challenging task. Concurrent systems, esp. when being large-scale, are known to be hard to design as the overall system behavior non-linearly results from local behavior and interactions. They are also hard to engineer and debug, as time dependent errors are often hard to reproduce. Simulation tools and environments are often used to assist in this...
According to the analysis of the transport system of pharmaceuticals cold-chain logistics, this article proposes that its network structure is of hub-and-spoke type. Combining with Characteristics of hub-and-spoke transportation network, aiming at the minimum total transportation cost, pharmaceuticals cold-chain logistics transportation network optimization should be conduct into two stages. The first...
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...
Provides a novel hybrid ant colony algorithm combining genetic algorithm with implicit parallel function to make up the shortcomings of common ant colony alogrithm in the vehicle routing problem including slow convergence in the early stages. Introducing the encoding and mutation operation can improve the efficiency of solving the optimal distribution path. The comparative analysis of vehicle routing...
We present a logistic scenario, based on the sea port of Bremen, and a context-aware dynamic service-based system to support its operation. We also show how we have used it to evaluate our automated adaptation techniques.
The European PLAY project aims at defining a federated-open-trusted platform able to deal with events emitted by any device. That platform should be able to combine a publish/subscribe mechanism with complex event processing in order to use the huge amount of produced events as a shared knowledge. The PLAY platform may so be able to (i) inform users (or devices) with relevant events and (ii) suggest...
This paper presents the construction of an aggregated indicator of a fuel-efficient driving style, in order to construct an efficient Ecological Driving Assistance System (EDAS). Such an eco-index can be used to detect eco-driving behaviour, but also to give to the driver useful advices to help him improving his driving efficiency without deteriorating safety. The logistic regression is used to model...
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...
