Carbon reduction effective advanced planning and scheduling (C-APS) system: framework, functions and empirical results

Purpose This study develops a carbon reduction effective advanced planning and scheduling (C-APS) system tailored for the manufacturing industry. Design/methodology/approach The system integrates a carbon emission calculation module to enhance production efficiency while achieving energy conservation and carbon reduction objectives. In this study, the proposed C-APS system was implemented in five manufacturing companies. The empirical results demonstrate that the system significantly reduces energy consumption and carbon emissions during production, particularly addressing the three categories outlined in the ISO 14064-1 standard. Findings The key findings include: (1) an average cumulative carbon reduction rate of 20% per enterprise within five years and (2) notable improvements in equipment utilization and order delivery rates. Additionally, the study highlights the critical influence of data accuracy and infrastructure completeness on system performance. Originality/value The proposed C-APS framework offers a practical carbon reduction strategy for the manufacturing sector, enabling companies to balance economic performance with environmental sustainability while advancing toward low-carbon manufacturing and smart transformation.
