摘要

This study develops a three-level sustainable production inventory model for the jewellery manufacturing industry with hybrid demand, production uncertainties, and environmental factors using pentagonal neutrosophic fuzzy numbers. To maximise economic and environmental performance, the model considers manufacturing, holding, ordering, deterioration, automation, and carbon emission costs, as well as green technology investments. Using metaheuristic algorithms, the system finds optimal production schedules and inventory cycles while retaining artisan quality. The technique indicates that new technology, when paired with sustainability measures, may improve the competitiveness of small and medium enterprises in the luxury goods market. The optimal results include raw material procurement time 0.66 months, intermediate manufacturing 0.82 months, final assembly and packaging 0.74 months, and inventory cycle 3.22 months; the total system cost is Rs. 1,429,827.62, with green technology investment of Rs. 93,000 and automation/Industry 4.0 cost of Rs. 799,496.00, ensuring a balance of economic efficiency, environmental sustainability, and quality preservation.
