Abstarct: According to the of the plan and schedule production space Decisions such as how special custom programs and schedules, and limited energy resources is of paramount importance. However, the role of these categories baxsed on their importance in the steel industry adds cost efficient management. Growing industries in recent decades and fierce market competition, to achieve pre-determined objectives and strategies need to plan production And can be explicitly claimed that no production planning and production scheduling is impossible to achieve predetermined goals. On the other hand, in recent years, with increased attention to issues and intensifying environmental regulations in this area, the steel industry as one of the polluting industries have been affected. One of the main challenges of the steel industry, production planning is that according to the custom of these products in the industry, production scheduling decision will be the most important issues. Also, due to the need for maximum use of storage capacity in the industry, addressing inventory planning is also essential. In this regard, the present study aims to provide a mathematical model of production planning and scheduling production, taking into account the time-dependent energy costs 1394-1395 were years in the steel industry What the proposed model, production planning and scheduling simultaneously considering the energy cost is considered. The need to do so in the proper use of available resources capacity and power machinery such as warehouse space and reduce energy costs in the steel industry. This model does have a key role in improving production planning the size of the steel industry through the production of various products, reduce excess inventory is in stock And thus reduce the cost of maintenance and proper use of available energy sources are necessary. Following the proposed model using optimization software Gams dissolved and its results, such as the production of each product on each machine, ideal capacity Stock for each product in storage at intermediate and energy consumption of each resource per month and one-year time horizon is provided. The results show that the proposed model scheduled for production in the steel industry due to the space requirements of its decision. baxsed on the results manufacture all products according to the current market demand is not acceptable and economically, and intermediate storage capacity For different products in different months of the year was determined and found that in the first quarter of energy consumption more than the other months of the year.
