چکیده :

Efficient production planning is essential for improving operational performance and reducing costs in precast concrete manufacturing plants. This study presents an integrated optimization model for procurement planning, production scheduling, and inventory management over a six-month planning horizon. The proposed model simultaneously determines raw material procurement quantities, production allocation, and inventory levels while considering supplier capacities, ware-house limitations, production capacities, and project demands. The objective is to minimize the total operational cost, including raw material purchasing and inventory holding costs, while ensuring complete demand satisfaction. The model was implemented and solved using the Firefly Algorithm (FA), and its applicability was evaluated through a real-world case study involving five construction projects and five types of precast concrete products. The results demonstrate that the proposed approach can generate feasible production and procurement plans, improve resource utilization, and support effective medium-term production planning. The developed framework can serve as a practical decision-support tool for precast concrete manufacturers and provides a foundation for future research on sustainable and intelligent production planning.
