The Iron and Steel Industry is a process industry and subject to continuous production. In the iron and steel sector, many companies producing solid steel form using raw iron ore work for full-day shifts. Production process is costly and laborious. Liquid iron ore must be continuously transported between the casting operations. Transportation problems cause high financial losses. In this study, we aim to increase the efficiency of torpedoes transferring the liquid steel between the casting operations in an iron and steel company. We introduce an event-based simulation model and propose not using the torpedo causing bottleneck in production. The torpedo used in the production is decided by Topsis method which is a multi-criteria decision-making approach. Comparing to existing system and the proposed approach using the simulation model, it has been observed that production quantity increases by %9,06 (13.215.33 tons of liquid iron on average per month) while the waste of time decreases by %66,35. |
