For machining workshops that use automated guided vehicles (AGVs) for material handling and management, workstation layout AGV path are coupling factors affecting the cost (MHC). The multi-row is a typical pattern in many workshops, currently, there lack of studies on problem (MRLP) while taking into account path. This study established bi-objective optimization methodology integrating to minim...

The problem of multi-vehicle path planning can be treated as a machine scheduling or a vehicle routing problem with definite temporal, spatial and other constraints. We consider the scenario of path planning of multiple Automated Guided Vehicles (AGVs) and Automated Trucks (ATs) in a Ship-Container Terminal area*. Our main focus is on developing global and local path planning methods for each o...

This paper suggests a routing method for automated guided vehicles in port terminals that uses the Q-learning technique. One of the most important issues for the efficient operation of an automated guided vehicle system is to find shortest routes for the vehicles. In this paper, we determine shortest-time routes inclusive of the expected waiting times instead of simple shortest-distance routes,...

To analyse an automated guided vehicle (AGV) system operating under selected vehicle routeing strategies, we present a simulation model that can handle an arbitrary system layout as well as arbitrary numbers of AGVs and pedestrians causing congestion in the system. We introduce a dynamic vehicle routeing strategy based on hierarchical simulation that operates as follows: at the time of each AGV...


 This study introduces methods of evaluating 3D perception systems, such as Time Flight (ToF) for automated logistics applications in unstructured environments. Here is defined a system’s understanding its environment and the Objects Of Interest (OOI) within that environment, through hardware consisting cameras or depth sensors. Current computer guided machinery rely on an Autonomous Guid...

In automated container terminals, containers are transported between ships and storage yard by differen types of vehicles, for example, guided vehicle (AGV, yard crane (YC) and quay crane (QC). To improve the productivity of the automated container terminals, it is important to harmoniously synchronize operations of different types of container handling equipment. This paper examines the schedu...
