| With the development of production and automatization, the tradition manufacturing's way have changed deeply, at the same time, the material conveyance's system should meet those demands of automatization, flexibility (adjustable) and just in time. AGVS's path planning has been developing into an important research field under such background. The paper analyzes workshop's manufacturing process and logistics system and designs the work shop plan; abstracts AGV's path map based on workshop's layout, uses Graphics Theory to describe AGV's path; after analyzes all kinds of ways of path-planning, get the shortest path from route planning by the way of application for GA. |
