Consider a manufacturing plant such as steel melting industries which is highly dependent on energy and produces a variety of products. Since the products are considered to belong to a single family, they can be represented by an aggregate product. We develop a multi-period model which simultaneously does aggregate production and energy planning.
Introduction. An aggregate crushing plant is a machine that processes a wide range of raw materials into high-quality aggregate, which is used in a variety of construction applications such as roads, buildings, and bridges. Designing an efficient crushing plant is critical to achieving maximum productivity, profitability, and sustainability in the aggregates industry.
Moving material (aggregate production stream, flowing material): Avoid areas where material may slide from stockpiles when on foot.
