Abstract
With the increase in electricity consumption in the country over the last few years, despite the strategic nature of the steel industry in the country, the supply of electricity for steel companies has faced serious problems; In this study, we have first examined the strategies for improving the quality and increasing the production rate of Gol Gohar Steel Company through forming a SWOT matrix. Then, considering that sustainable electricity supply is identified as the key strategy to achieve this goal, using multi-criteria decision-making methods, different power plants are ranked for electricity supply of this company. For this purpose, using two main indicators of maintenance planning, i.e. reliability and availability, the options have been evaluated, and the ranking of power plants has been done using different methods: AHP, EDAS, TOPSIS, and MAUT. Also, for the weighting of criteria, two methods of forming a pairwise comparison matrix (PCM) and Shannon's method have been used. The results indicate that among the three power plants—Kahnouj, Goharan, and Samangan—the power supply from the Samangan power plant will be the most reliable for the Golgohar company. Specifically, in three out of four decision-making methods, the Samangan power plant was identified as the best option, while it ranked second in the remaining method. Additionally, the Kahnouj power plant and the Goharan power plant were identified as the second and third-best options, respectively.
