Abstract: A dynamic scheduling model of RGV with minimum basic action period is proposed for the two key problems of real-time scheduling and fault scheduling of RGV based on a detailed analysis of the working principle of linear RGV. The RGV scheduling strategy of this model is to let the RGV select the CNC with the minimum basic action cycle time for service in each scheduling. The basic action cycle time of the RGV is the sum of waiting, motion, loading and unloading, and cleaning time for a CNC that processes the first process in a one-step process or a multi-step process without clinker. For a CNC that processes the first process in a two-process process with clinker, the basic action cycle time of the RGV is the sum of wait, motion, loading and unloading, motion, loading and unloading, and cleaning time. The RGV scheduling model is simulated and solved by matlab programming, and the solution results show that this RGV dynamic scheduling strategy can effectively improve the efficiency of the RGV vehicle.
