In recent times flexible manufacturing systems emerged as a powerful technology to meet the continuous changing customer demands. Increase in the performance of flexible manufacturing systems is expected as a result of integration of the shop floor activities such as machine and vehicle scheduling. The authors made an attempt to integrate machine and vehicle scheduling with an objective to mini...

Discrete-event simulation model was developed to evaluate the performance of an automated material handling system (AMHS) for a wafer fab with a zone control scheme avoiding all vehicle collision. The layout of this AMHS is a custom configuration. The track option contains turntables, turnouts and high-speed express lanes. The behavior of the interarrival for all stockers from the real data set...

The tandem loop with multiple vehicles (TLMV) configuration is proposed as a new and effective alternative for automated guided vehicle systems. The TLMV configuration is useful for a large scale manufacturing environment since it can easily accommodate expansion or upgrade while still being less sensitive to vehicle failure than the tandem loop (single vehicle) configuration. Simulation result...

The performance evaluation of an obstacle detection and segmentation algorithm for Automated Guided Vehicle (AGV) navigation in factory-like environments using a 3D real-time range camera is the subject of this paper. Our approach has been tested successfully on British safety standard recommended object sizes and materials placed on the vehicle path. The segmented (mapped) obstacles are then v...

units output by some cells have to be carried to other units. An automated guided vehicle (AGV) is a vehicle which carries the units among the cells by moving around in a space which is composed of guidepaths. The space is logically composed of space objects structured in a tree, where high-level space objects denote broader and more abstract space. In this paper, we would like to model the mov...

Industry 4.0 is a promising solution for the management of manufacturing processes, due to its potential to increase both energy saving and optimized production. Within this context, in this paper we propose the use of automated connected vehicles fleets for the autonomous handling of products among workstations in manufacturing processes. Numerical results confirm its effectiveness w.r.t a typ...

Flexible Manufacturing System (FMS),equipped with several CNC machines and Auto Guided Vehicle (AGV) based material handling systems has been designed and implemented to have the flexibility and efficiency in production process. After the implementation of FMS, various problems came such as the scheduling of the resources, such as frequent variation in the parts, tools, AGV routings, becomes a ...

The explosive growth in the freight volumes has put a lot of pressure on seaport authorities to find better ways of doing daily operations in order to improve the performance and to cope with avalanches of containers processing at container terminals. Advanced technologies, and in particular automated guided vehicle systems (AGVS), have been recently proposed as possible candidates for improvin...

This paper describes the intelligent Automated Guided Vehicle (AGV) control system using Fuzzy Rule Interpolation (FRI) method. The AGV used in this paper is a virtual vehicle simulated using computer. The purpose of the control system is to control the simulated AGV by moving along the given path towards a goal. Some obstacles can be placed on or near the path to increase the difficulties of t...

he aim of the project is to build an assembly station with the preventive section under the process of poke yoke system. Poke yoke is the general methodology following in industry to avoid mismatching product in assembly stations. The main aim of this project is to avoid assembling process when the sequential procedure is not followed. The project also deals with AGV – Automatic Guided Vehicle....
