The invention discloses a forming workshop energy-saving dispatching method based on a genetic simulated annealing algorithm. The forming workshop energy-saving dispatching method comprises the following steps that 1, an initial production scheme is generated; 2, an analysis period is set; 3, a production model for the total processing energy consumption and the processing time of the forming workshop is constructed; 4, a corresponding constraint condition is set to form a multi-objective optimization model; 5, relevant information is acquired, and the genetic simulated annealing algorithm isused for solving the multi-objective optimization model according to the collected information to obtain a production scheme of the analysis period; 6, it is judged that whether the production schemeof the analysis period is superior to the production scheme of previous analysis period, if yes, production is arranged according to the production scheme of the analysis period, and if not, production is continued according to the production scheme of the previous analysis period; and 7, a next production period begins and the step 5 is executed. The method can obtain an optimal production schemewith lowest energy consumption and shortest time in real time and perform production and processing, so that productivity is improved, and production cost and energy consumption are reduced.
