[Abstract]:In modern manufacturing, flexible manufacturing system (FMS) has been widely used because of its ability to respond to market changes quickly and be suitable for medium and small batch production. Modeling theory, production scheduling algorithm is the focus of research in the field of flexible manufacturing systems is also a difficult point. In addition, the implementation of flexible manufacturing system, the communication between equipment and the design of management system are also the focus of research. In this paper, the problems mentioned above are studied, and the solutions are given, which are successfully applied in the development of FMS control and management software, combined with the project of "the development of intelligent flexible manufacturing cell scheduling simulation system and equipment development". This paper focuses on FMS modeling, production scheduling algorithm and control software implementation. The main work is as follows: first, FMS modeling, using object-oriented Petri net to model flexible manufacturing system, gives the machine tool. The object oriented subnets of loading and unloading manipulator, stereo warehouse, automatic transport vehicle and input and output buffer are discussed. The method of synthesizing the whole system from each object subnet is discussed. Secondly, in the aspect of FMS scheduling algorithm, a virus genetic algorithm with catastrophe factor is proposed to solve Job Shop and Flow Shop problems in static scheduling, and compared with genetic algorithm and virus genetic algorithm. The validity of the algorithm is proved. In addition, a dynamic scheduling strategy based on queuing queue model is presented, and several common scheduling rules are listed. Thirdly, the FMS control software is introduced in detail. The running flow of flexible demonstration line for automatic machining and testing of claw workpiece is introduced in detail. The communication technology between FMS control software and machine tool and FANUC robot is analyzed, and the motion control instruction of the system is designed. On the basis of demonstration line, a relatively complete FMS machining control management information system is developed, and a database is established, which can manage the whole process information of the workpiece. The system has been tested and verified that the system has good performance.
