The Simulation Study on Dynamic Optimization of Hydropower Project Earthwork Allocation System Based on Petri Net

This paper makes use of the characteristics of the Petri net, which describes the discrete event system effectively. Based on the principle of Petri net in arrangement and the characteristic of the Earthwork allocation system, the model of Earthwork allocation system is established by level, and finally the Petri net shape of the Earthwork allocation system is formed. It embeds linear programming model and queue theory into the Petri net, and then works out. It is proved that the simulation is effective and feasible in the project.
