<p><b>Новая страница</b></p><div>We have the conveyor with $10\le M \le 100$ stations for hand selection of products items to boxes. The volune of box is $V_b=0,034$.<br />
<br />
List of sku is in SKU.xlsx file.<br />
<br />
Each box moves from the beginning to the end of conveyor throu the set of stations $Z=\{z_1, z_2 dots, z_M\}$.<br />
<br />
Each station works with zone, including the set of positions $N_m$.<br />
<br />
The structure of store is in ZONES+positions.xlsx file<br />
<br />
Each position is for one type of goods.<br />
<br />
The $sku$ coluld be assignned with position only if position is empty.<br />
<br />
The hand selection time for row is the functon of SKU, position number and quantity of items per row.<br />
<br />
$$G(sku,qty, zone, position)=3600/Productivity* '''Qty'''+comfort+scan*T_sc*'''Qty'''$$<br />
<br />
$T_sc=1$ - scanning time.<br />
<br />
For comfort we will use the listed times:<br />
<br />
AA 5 <br />
<br />
AB 10<br />
<br />
AC 11.25<br />
<br />
BA 12.5<br />
<br />
BC 15<br />
<br />
CA 17.5<br />
<br />
CC 20<br />
<br />
Д 22.5<br />
<br />
ST 50<br />
<br />
OБ 150<br />
<br />
and is tabulated in our case. <br />
<br />
Each zone has $N_z$ positions.<br />
We will assume that each position could be loaded from store any time we need in. <br />
<br />
The source data is the set of rows per day:<br />
<br />
sku - good type<br />
qty - quantity<br />
datetime - dte and time <br />
order - номер заказа <br />
<br />
<br />
Box moves with $v=0.6m/s$ from one section to another. <br />
<br />
The distance between the stations is $a=8m$.<br />
<br />
We should propose the input goods flow routing to zones and positions to minimize the time $T$ for daily hand selection.<br />
<br />
It is necessary to estimate the mean and variance.<br />
<br />
The model should be described in latex as an instruction and description and uploaded to https://drive.google.com/drive/folders/1p9uMrZAzSLQwQt3uGLilIxYZK9VlmDX2?usp=sharing.</div>imported>AlexHel
