question

Apologies, I didn’t express myself clearly earlier.

I am currently using an Item List that records startcp, startstation, endcp, and endstation. Then, I Push To List, allowing the AGV to Pull From List and determine the transportation task based on the startstation and endstation stored in the item. This enables the AGV to pick up the item from its current location (startstation) and transport it to the designated destination (endstation).

As shown in the diagram, my current setup follows a from-to transportation model.

However, I would like to store the startstation and endstation of the items separately into two different lists.

Why do I want to do this?

In the next step, I plan to calculate the starting locations (startstation) of the items waiting to be transported (since my AGV can carry up to four items at a time). Then, I will compare the distances between these locations to determine the optimal sequence for picking up the items and planning the transportation route.

For example, suppose I have three items waiting for transport:

Item A: startstation = 1, endstation = 6

Item B: startstation = 3, endstation = 5

Item C: startstation = 2, endstation = 4

If the stations are arranged in a straight line from left to right in the order {1, 2, 3, 4, 5, 6}, and the distances between them are equal, then my AGV should optimize its travel route as follows:

Load A at Station 1

Travel to Station 2 → Load C

Travel to Station 3 → Load B

Travel to Station 4 → Unload C

Travel to Station 5 → Unload B

Travel to Station 6 → Unload A

What I need help with

To achieve this shortest path optimization, my first step is to separate startstation and endstation into two independent lists (FromList and ToList) to facilitate the next steps of my algorithm.

I am wondering how I can separate startstation and endstation into two different lists while ensuring that the AGV can still correctly match the corresponding items during transportation.

Seeking Advice

Additionally, I am not entirely sure if this approach is feasible or if there is a better way to achieve my goal. If you have any suggestions or alternative methods that could help me implement this efficiently, I would greatly appreciate your insights!

Thank you!
