According to the main characteristics of production line of iron and steel enterprise, how to make aggregate production planning of iron and steel enterprise are analyzed. An aggregate production plan model of product line of iron and steel enterprise is proposed, which is calculated by using standard library function of the Matlab7.0 genetic algorithm toolbox to program. Penalty function was adopted in the course of getting solution. These parameters of scale of father population, crossover probability, mutation probability and penalty factor were combined and optimized. The result obtained is in accordance with the actual conditions of this enterprise basically that the optimization solution to production plans of real iron and steel enterprise by using the algorithm.10aAggregate production plan model10aGenetic Algorithm10aIndex terms -iron and steel enterprise10aMATLAB10aProduction line1 aJiang, G.1 aHe, E.1 aLi, G.1 aKong, J.1 aXie, L.  uhttp://www.scopus.com/inward/record.url?eid=2-s2.0-84879110969&partnerID=40&md5=f4274b55fafe675f163de08cb3f49a87
