Abstract: To solve the problem of enterprises energy-saving, the method of First-Order Hybrid Petri Net(FOHPN)was employed to build enterprises energy-saving production dispatching optimization model. Aiming at objective function of energy-saving production in enterprises production process, the method of linear programming was used to optimize objective function of energy-saving production based on enterprises production dispatching. And the best enterprises energy-saving production strategy was given. The practical example proved that the proposed method had important theoretical significance and practical guiding significance for enterprises energy-saving.
