Production planning of aluminum enterprizes based on JUST IN TIME

This paper establishes a linear medium-term production scheduling model for delivery commitment, resources utilization optimization and minimum production cost in accordance with the production plan characteristics of aluminum industry, including hierarchical order, large scale and multiple constraints. Based on the characteristics of actual process and production management requirements of aluminum industry, we take the logistics morphology and costs of the whole process, from raw materials procurement to the final products, into account. A planning model is constructed from the perspective of logistic balancing to optimize the production cost. The effectiveness and feasibility of the model is verified by the actual production data. The data shows that the model is in accordance with the actual production conditions.
