| dc.description.abstract | The thesis investigates the significant challenges of rework waste and productivity inefficiencies at Abyssinia Integrated Steel Manufacturing, a prominent Ethiopian producer of rebar. Over the period from 2013 to 2015, the company experienced an average rework waste of 6,500 kg annually, underscoring the critical need for systematic improvements within its production processes. The primary objectives of this research are twofold: first, to conduct a comprehensive Value Chain Analysis (VCA) to identify key inefficiencies across the production stages; and second, to develop strategic interventions aimed at enhancing competitiveness and operational performance. The study employs a mixed-methods approach, integrating qualitative insights from interviews with production and quality control staff, alongside quantitative data analyzed using PROCAST simulation software. This software facilitates detailed modeling of thermal stress and solidification behaviors during the continuous casting process. The findings reveal that the improper control of casting parameters, particularly temperature and speed, is a major contributor to defect rates. Specifically, the research identifies an optimal casting temperature range of 1650°C to 1700°C and a casting speed of 1.5 m/min as critical conditions for minimizing turbulence and ensuring effective solidification. These parameters significantly reduce the incidence of defects, such as longitudinal and transverse cracks, which have plagued the production process. In conclusion, this study underscores the importance of integrating VCA with predictive simulation tools to create a robust framework for quality control and operational decision-making. By systematically identifying and addressing inefficiencies, Abyssinia Integrated Steel can enhance resource utilization, improve worker safety, and bolster its competitiveness in both domestic and international markets. The implications of this research extend beyond the case study, providing a valuable framework for other manufacturers in developing countries aiming to align production efficiency with quality standards through data-driven and strategic interventions. This approach not only contributes to operational excellence but also supports sustainable manufacturing practices in the steel industry. | |
