Abstract: Taking into account the emissions trading scheme and production capacity of enterprise, a hybrid production optimization model for multi-cycle engine manufacture /remanufacture, is built. The objective is the minimum production costs after considering the cost and revenue generated from emissions trading. It proposes an improved discretization gravitational search algorithm, which brings in mutation operators to increase the diversity of population in order to avoid premature convergence and local optimum. Examples prove the feasibility and the validity of this algorithm.
