Abstract:For multi-objective green job shop scheduling problem ( GJSP) , a multi-objective GJSP model was established with makespan, total carbon emissions and total tardiness as objectives. An improved NSGA-Ⅱ algorithm was proposed to solve the problem. The total carbon emissions objective function was designed in the model considering the carbon emissions during machine adjustment status caused by job fixture replacement, and a local search strategy based on N5 neighborhood structure and non-dominated sorting was designed. Finally ,some instances of GJSP were designed to test the proposed algorithm. The calculation results showed that for the optimization of multiple objective functions, the improved NSGA-Ⅱ found that the equilibrium solution had a relatively higher non-dominated level. For the optimization of a single objective function, the objective function value is relatively lower. The research showed that the improved NSGA-Ⅱ had better optimization effect. The experimental results verified the effectiveness of the proposed algorithm.
