Roads in the affected areas are usually damaged during big natural disasters, and it results in blocked road, reduced road capacity, lower vehicle speed and severe restrictions for travelling. Besides, vehicles are donated temporarily by numerous groups and various in their performance. This paper takes the above problems caused by road damage into consideration, and the vehicle route decision are...
During operations, networks are typically analysed in terms of metrics such as throughput, delay and connectivity. Analysis and optimisations can be carried out on these metrics to achieve better networks; however, such approaches rely on strong processing power and a substantial amount of data collection. This may pose a problem as processing power is related to the cost of the platform, and data...
This paper proposes a more accurate way to detect the logistics driver fatigue state. In logistics transportation vehicle driving process, there are differences between the blinking frequency and the closing time of logistics driver's eyes. According to the difference, the logistics driver's fatigue state can be able to be detected. Using the computer, it can strengthen the processing to the image...
As one of the mega cities in the world, to meet the needs of its population, DKI Jakarta not only faces logistics problem which is low availability, but also transportation problem which is traffic congestion. Those problems show that DKI Jakarta needs an urban logistics system that is not only effective and efficient, but also that does not add its transportation problem. Urban logistics system that...
In cross-docking operations, planners need to coordinate the inbound, docking and outbound logistics operations to ensure a smooth flow of goods across the supply chain. The operation management of cross docking is a crucial task with high complexity for the logistics systems. This paper attempts to address the Vehicle Routing Problems (VRPs) of distribution centers with multiple cross-docks for processing...
Autonomous guided vehicles have major benefits in terms of a rail bound conveyor technology because they are able to respond flexibly to changes in the application area. In many areas, safety-related position detection is necessary to avoid accidents. Derived from this position the driving speed in the work areas can be reduced in a safe way and minimum distances can also be observed in a safe manner...
Multi and intermodal freight transportation refers to moving loads by a sequence of transportation modes linked by mode-to-mode transfers performed at intermodal terminals, generally without directly handling the goods. Such transportation systems and the carriers that provide the associated services are often organized according to consolidation principles. Consolidation of the shipments of different...
It is widely known that many traffic accidents occur every year, not only in Japan but also in the world. Drowsiness or sleepiness, which is the cause of dozing at the wheel, happens regardless of the physical condition of the driver after having meals or during midnight. This means that to avoid driver's drowsiness or sleepiness by oneself is hard. Therefore, various systems have been proposed to...
The Cumulative Capacitated Vehicle Routing Problem with Time-Dependent Demand(CCVRP-TDD) is a novel problem in humanitarian logistics where the demand is dynamic and the objective is to minimize the sum of arrival times at critical nodes due to the emergency of the situation. Critical nodes are the nodes closest to the source, from which people try to flee to seek first aid, food, etc. This mobilization...
Good transportation is a key activity within the supply chain, as it has a direct impact on the company's total costs and in customer's service, giving it a special interest for seeking ways to optimize these distribution processes. In the literature there is a large number of approaches to optimize these processes, which generally require advanced methods for its solution. This article reviews the...
Several factors must usually be taken into account when deciding the design of a supply chain network. In most cases, the economic impact and the resulting service quality are the most common. In this sense, one of the strategies with a big impact in both factors is which inventory centralization level is the most appropriate. High decentralization levels usually provides a better service but with...
This paper describes innovative sensing technologies and control techniques, that aim at improving the performance of groups of Automated Guided Vehicles (AGVs) used for logistics operations in industrial environments. We explicitly consider the situation where the environment is shared among AGVs, manually driven vehicles, and human operators. In this situation, safety is a major issue, that needs...
This paper focuses on the integration of advanced sensing and control technologies into advanced systems of multiple Automated Guided Vehicles (AGVs). In particular, we focus on the key technologies developed within the Plug-and-Navigate Robots (PAN-Robots) project, highlighting how those results contribute to improving the performance of AGV systems.
This paper introduces a novel Human Machine Interface (HMI) that allows users to interact with a fleet of Automated Guided Vehicles (AGVs) used for logistics operations in industrial environments. The interface is developed for providing operators with information regarding the fleet of AGVs, and the status of the industrial environment. Information is provided in an intuitive manner, utilizing a...
A consortium consisting of five Hungarian institutions of higher education during the past two years, using European Union's support performed workout of a project that connected to development of industrial relations, to education development, to expansion of research cooperation, of international relations and to development of university organisation services on the territory of vehicle industry...
In large or medium retail enterprises, the downstream of the supply chain is usually composed by distribution centers or various warehouses. Since the distance of each distribution route is large, so the optimization of path is very important for the cost control and profit maximization of the enterprise. This paper uses Dijkstra Algorithm to solve the shortest path problem, and uses the method of...
The problem of continuous curvature path planning for passages is considered. This problem arises when an autonomous vehicle traverses between prescribed boundaries such as corridors, tunnels, channels, etc. Passage boundaries with curvature and heading discontinuities pose challenges for generating smooth paths passing through them. Continuous curvature half-S shaped paths derived from the Four Parameter...
Lately, the Vehicle Routing Problem (VRP) in the city, known as City VRP, has gained popularity with its importance in city logistics. Similar to city logistics, City VRP mainly differs from conventional VRP in terms of the stakeholders involved, namely the shipper, carrier, resident, and administrator. Accordingly, this paper surveys the City VRP literature categorized by stakeholders and summarizes...
With the development of automated logistics systems, flexible manufacture systems (FMS) and unmanned automated factories, the application of automated guided vehicle (AGV) gradually become more important to improve production efficiency and logistics automatism for enterprises. The development of the AGV systems play an important role in reducing labor cost, improving working conditions, unifying...
Aimed at the problem of commercial vehicles' distribution routes and transportation mode, as well as the reliability of service, a distribution optimization model is constructed which considered the transportation cost, transit cost and punishment cost. Then apply genetic algorithm to solve the problem. Finally, used the data from a vehicle logistics enterprise for analyzing, which proved that the...
