Nowadays, Strategic planning in the industry plays a crucial role in a country's economic growth and capital development. One of the critical industries known as one of the main infrastructures for economic growth is the steel industry. Due to the wide range of final products and extensive uses, strategic planning is critical in the steel industry. Prioritizing the most valuable products in order to obtain sustainable development is one of the key points in the strategic planning of the Iranian steel industry. According to the resources and the growing environmental concerns, it is necessary to choose products for investment that can give rise to sustainable development for the country's economy. In this research, after reviewing the existing literature on the strategic planning of the steel industry and multi-criteria decision-making as one of the practical tools in this field, 10 higher value-added steel products and 18 criteria With the opinion and approval of Iran's steel industry experts were identified in three sustainable developments dimensions. Then, the impact of these criteria on each other was eva‎luated by industry experts, and the weight of the criteria was obtained using the fuzzy DANP (DEMATEL Based ANP) method. In the next stage, four multi-criteria decision-making methods, including COPRAS, WASPAS, TOPSIS, and VIKOR, under uncertainty conditions with the approach of grey numbers, were used to rank the options separately. Then, using Copeland's method, the results of these applied methods were combined to generate the final result. Rebar was selected as the best product, and rail and other steel sections like angle sections were selected as the worst products in the current situation of Iran in the direction of sustainable steel industry development. Finally, in order to obtain a sensitivity analysis of the relationship between products and sustainable development, in three different steps, one of the dimensions was removed, and the problem was solved with two others to measure their impacts.
