We consider a multiproduct, single-stage, single-equipment batch-processing scheme and address the problem of determining the timing and duration of product campaigns to minimize average setup, quality, and inventory holding costs over a horizon. We formulate the deterministic, static version of this problem over an infinite horizon.

Watering can prove challenging to even the proudest houseplant owners, especially when it comes to members of the ficus family. The Fiddle Leaf Fig (ficus lyrata) is especially notorious for frustrating its owners with its picky watering needs. First-time owners of these plants are prone to overwatering, which can lead to health issues such as root rot.

The primary objective in a batch distillation is to minimize both batch cycle time and heat input by optimizing the number of stages and reflux ratio to achieve the required separation [3, 5]. The process variables are interdependent as determined by the mass and energy balances and the mode of operation. The reflux ratio. R = L/D (6)

Let us recall that the constant time and size factor model is the most widespread to design multiproduct batch processes. These models are used to optimize the plant design by proper selection of batch sizes of each product, the operating times of semi-continuous units and the structure of the plant.
