Modified Banker's algorithm for scheduling in multi-AGV systems

2011 IEEE International Conference on Automation Science and Engineering, 2011
In today’s highly complex multi-AGV systems key research objective is finding a scheduling and routing policy that avoids deadlock while assuring that vehicle utilization is as high as possible. It is well known that finding such an optimal policy is a NP-hard task in general case.

AGV scheduling system based on MQTT protocol

2021 4th International Conference on Advanced Electronic Materials, Computers and Software Engineering (AEMCSE), 2021
This paper describes the AGV scheduling system based on mqtt protocol. The traditional AGV scheduling system uses TCP protocol to communicate with nodes directly, which takes up the resources of the system operation greatly when there are many nodes. This system is developed twice based on opentcs platform, and an AGV scheduling system based on mqtt ...

Scheduling and routing algorithms for AGVs: A survey

International Journal of Production Research, 2002
Automated guided vehicles (AGVs) are now becoming popular in automated materials handling systems, flexible manufacturing systems and even container handling applications. In the past few decades, much research has been devoted to the technology of AGV systems and rapid progress has been witnessed.

Models for AGVs’ Scheduling and Routing

2015
An automated guided vehicle (AGV) is a driverless material handling system used for horizontal movement of materials. AGVs were introduced in 1955 (Muller, 1983). The use of AGVs has grown enormously since their introduction. The number of areas of application and variation in types has increased significantly.

AGV scheduling for automated material distribution: a case study

Journal of Intelligent Manufacturing, 2009
We have studied the scheduling of automated guided vehicles (AGVs) for efficient and uniform material distribution from a truck-dock to machining units of the machine shop in an automotive manufacturing plant. The material distribution problem, being a much simpler special case of the more general material transfer problem, is easily amenable to ...

Scheduling control of AGV system based on game theory

2013 6th IEEE/International Conference on Advanced Infocomm Technology (ICAIT), 2013
This paper does a research on how to improve the operating efficiency of the multi-AGV system, and establish the AGV scheduling model with an algorithm that is designed to optimize scheduling process. The algorithm confirms the initial scheduling strategy first, and then optimal scheduling based on game theory.

A declarative approach for AGVs modeling and cyclic scheduling

2012
In this paper, we deal with the cyclic scheduling problem usually observed in the FMS producing multi-type parts where the AGVS plays a role of a material handling system. Finding the conditions guaranteeing the AGVs dead-lock-free and collision-free movement policy is the aim of this work.

Scheduling and Re-scheduling of AGVs for Flexible and Agile Manufacturing

1995
This chapter deals with a. modeling and scheduling flexible and agile manufacturing system (FAMS) using AGVs, and b. re-scheduling the system in the case of trouble, by using Timed Petri Net (TPN). The purpose is 1. to provide a solution to the coordination problems of AGVs transferring a series of jobs to the appointed machining cells so as to ...

A reinforcement learning method for multi-AGV scheduling in manufacturing

2018 IEEE International Conference on Industrial Technology (ICIT), 2018
This paper addresses a multi-AGV flow-shop scheduling problem with a reinforcement learning method. Each AGV equipped with a robotic manipulator, operates on the fixed tracks, transporting semi-finished products between successive machines. The objectives dealt with here is to obtain a AGV schedule that minimize the average job delay and total makespan.
