In today's industrial and competitive world, the optimal use of time, resources, and timely and correct response to market needs are crucial. On the other hand, the importance and necessity of optimizing production based on market demand will reveal the need to manage high-value-added products. Regarding this fact that the steel industry is one of the basic industries and has a great influence upon the other industries, its productivity can affect itself as well as the other industries. The scope of this study is Isfahan Steel Corporation which is considered as one of the greatest plants throughout the country manufacturing steel products such as iron beams. Thus in this study, the corresponding documents and proofs were examined to optimize the beam products of Isfahan Steel Corporation based upon the market demand and increased value, and considering the records, opinions of production and sale experts, customers, and suppliers, a questionnaire was prepared to estimate the types of beam and distributed among customers and suppliers and analyzed. Then, the added value of beams was calculated and finally, the number of beam products was calculated based on estimated market demand using the model ARIMA.
