Abstract
Supplying raw materials plays a central role in the Iran׳s crude steel plants. Iran׳s scrap recycling industry, as a major supplier of steel scraps, requires identifying and performing the efficient strategies to utilize the substantial amount of steel scrap. In this research, by designing a model and implementing the efficient strategic factors (Strengths, Weaknesses, Opportunities and Threats), via the SWOT analysis, the appropriated strategies, SO, ST, WO and WT are determined. This model consists of four factors, 14 sub-factors and eight strategies. Since the SWOT method is unable to rank the factors and strategies, the MADM technique is applied to prioritize them. The dependency between the factors affects the priority of strategies. Therefore, AHP and ANP methods are applied discretely to examine whether the dependency among the factors changes the priorities of strategies
Comparison of the outcomes from the AHP and ANP methods presents that the dependency among the factors in ANP method causes major changes in ranking the alternatives particularly for the principal alternatives
