Optimal Design And Scheduling Simulation Study On The Ammunition Transport System

As the key problem of the naval gun, the quality of ammunition scheduling strategy couldreflect the fighting ability of the naval gun. So it is very important to proceed the research onthe scheduling strategy of the ammunition transport system. In this paper, the ammunitiontransport system is the research object. Combined the modular design theory and consideringthe shortest time for bombs as the objective function, the structural design for every functionmodule of the transport system is proceeded. The scheduling model is established and simulated.Finally, the scheduling verification experiment about the prototype is in progress.Firstly, based on the comprehensive analysis of the transport system of various automationnaval guns around the home and abroad, this paper proposed an ammunition transport systemwith buffer bomb box. It divided the ammunition transport system into user layer, function layerand equipment layer. Combined with the modular design theory, the equipment layer is dividedinto storage module, transfer module, raise module and buffer module. Then proceed thestructure design for each function module.Secondly, aim at the scheduling problem of the ammunition transport system, this paperascertained the optimized scheduling path of the ammunition transport system with OOTCSPNmodeling method based on the analysis of the working process and the application scope ofPetri nets. Consider the shortest time for bombs as the objective function. This paper built theOOTCSPN scheduling model for the four function modules. Four PN models are linked to bethe OOTCSPN scheduling model of the ammunition transport system through the doortransition. And then, the analysis about reachability and boundedness and conservativeness areproceeded.Furthermore, this paper had a parallel sequential logic simulation analysis on establishedPN model using Stateflow software, analyzed different function module logic sequence curveswhich were generated by Stateflow software to determine the best feed ammunition sequence ofammunition transport system and took it as the basis for host machine scheduling control.Finally, proceeding several scheduling experiments to the ammunition transfer prototypebased on the software of LabVIEW. To validate the optimality of the scheduling strategy, in thispaper, there are two kinds of experiments. One is proceeded with stochastic scheduling strategyand the other is proceeded with the strategy which comes from the simulation results based on Stateflow. Transfer the sampled data to the user by the serial port communication of VISA. Andthen proceed temporal analysis and compare the results with different strategy.The research results about the scheduling problem of the ammunition transport system inthis paper are helpful. They have the certain reference value in extending and using of the Petrinets in the modern logistic scheduling system.
