We have the conveyor with $10\le M \le 100$ stations for hand selection of products items to boxes.
Each box moves from the beginning to the end of conveyor throu the set of stations $Z=\{z_1, z_2 dots, z_M\}$.
Each station works with zone, including the set of positions $N_m$.
Each position is for one type of goods.
The $sku$ coluld be assignned with position only if position is empty.
The hand selection time for row is the functon of SKU, position number and quantity of items per row.
$$G(sku,qty, zone, position)$$
and is tabulated in our case.
Each zone has $N_z$ positions. We will assume that each position coukd be loaded from store any time we need in.
The source data is the set of rows per day:
sku - good type qty - quantity datetime - dte and time order - номер заказа
Box moves with $v=0.6m/s$ from one section to another.
The distance between the stations is $a=8m$.
We should propose the input goods flow routing to zones and positions to minimize the time $T$ for daily hand selection.
It is necessary to estimate the mean and variance.
The model should be described in latex as an instruction and description.
