Research On Multi-load AGV Scheduling System For FMS

The goal of high-quality development in the manufacturing industry promotes the digital and intelligent transformation and upgrading of manufacturing enterprises.Through the optimization of enterprise resources,the production efficiency and production cost can be improved and reduced.Among them,the intelligence of logistics is one of the important contents of enterprise resource optimization.AGV is the key to realize intelligent logistics equipment,this paper around the characteristics of flexible manufacturing system,the AGV car path optimization and resource optimization configuration problem,the problem is to improve the whole logistics system efficiency to shorten the production cycle and reduce the production cost is one of the key problems to be settled urgently,optimizing the allocation of resources to the enterprise,achieve high quality enterprise development has the vital significance.First,AGV work environment modeling method is studied,through detailed analysis of the existing map modeling method,combined with FMS application scenario requirements,choose the topological map as a way to map modeling and design according to the requirements of the topological map modeling steps and the topology map data items and storage structure,the establishment of a workshop at the scene of topology map,lay the foundation for follow-up study.Secondly,combining with the characteristics of path optimization algorithm,studies the single AGV path planning problem for traditional A * algorithm in the process of route search is the actual cost function and weight of estimated cost function inequality and path planning problems such as turn more nodes,by introducing the dynamic weight and cost function of turning,an improved design of the A * path optimization search algorithm At the same time,on the basis of improving the search algorithm of A* path optimization,the multi-agv path planning problem is studied,and A two-stage conflict resolution scheme with time window is proposed,which can reasonably solve various types of path conflicts under the premise of ensuring the system efficiency,and ensure the efficient and orderly operation of AGV system.Thirdly,combined with the characteristics of FMS,aiming at the problem of system efficiency upper limit in single-load AGV scheduling optimization,this paper studies the scheduling and resource allocation of multi-load AGV,proposes a multi-load AGV scheduling method,and makes multi-load scheduling execution rules.At the same time,as a logistics resource,an AGV quantity optimization allocation model under multi-load condition is proposed to improve the utilization rate of AGV vehicles and optimize the quantity allocation of AGV vehicles.Finally,completed AGV scheduling system design and development of the overall architecture of scheduling system design and function module,in Visual Studio 2013 environment,using C# to load more AGV dispatching system development,through the system of AGV simulator of AGV collision simulation experiment was carried out and many AGV scheduling simulation,verify the collision avoidance scheme is proposed in this paper and the feasibility and effectiveness of the scheduling method.
