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...
This paper proposes a mixed integer-programming model for order planning of iron-steel enterprise. Because this problem is a kind NP-hard problem and the size of this problem is bigger, the genetic algorithm based on repeatable natural scale code and 3-mutation operator is presented to solve the model. For ensuring the quality of copy strategy of the genetic algorithm, this paper develops an improving...
