Aimed at the problems of low search efficiency A* algorithm in global path planning, not considering size AGV and too many turns, DWA easily falling into local optimization, an planning based on improved fusion is proposed. To begin, obstacle rate coefficient added to algorithm’s evaluation function build adaptive cost function; safety are increased by improving mode; extracting key nodes, a co...

Scheduling of vehicles in the container terminal is often studied as a static problem in the literature, where all information, including the number of jobs, their arrival time, etc., is known beforehand. The objective is generally minimizing the total travelling and/or waiting times of the vehicles. When the situation changes, for example new jobs arrive or a section of the terminal is blocked...

This paper describes the role of the Primitive Mobility (PrimMob) module within the Mobility Open Architecture Simulation and Tools(MOAST) environment. Descriptions are given of several alternative implementations of the module motivated by a desire to make MOAST more usable for an industrial Automated Guided Vehicle(AGV). A series of performance metrics is described as a series of tests that a...

This paper presents a heuristic for the dynamic vehicle scheduling problem with multiple resource capacity constraints. In the envisaged application, an automated transport system using Automated Guided Vehicles, bottleneck resources are (1) vehicles, (2) docks for loading/unloading, (3) vehicle parking places, and (4) load storage space. This problem is hard, because interrelated activities (l...

This paper investigates an improved genetic algorithm on multiple automated guided vehicle (multi-AGV) path planning. The innovations embody in two aspects. First, three-exchange crossover heuristic operators are used to produce more optimal offsprings for getting more information than with the traditional two-exchange crossover heuristic operators in the improved genetic algorithm. Second, dou...

This paper focuses on the design of a highly efficient Automated Guided Vehicle (AGV) transportation system. Therefore, we attempt to construct detailed system management models that include agent cooperation, container storage scheduling, and container transportation planning. We then optimally design systems that are constructed with the use of these management models. The systems are compare...
