QUESTION
In my model I have some forklift fleets which started out as simple Resources, but I decided to improve the model by replacing them with free-space Transporters.
My problem is that this seems to lower the simulation speed drastically in virtual time mode even if nothing is happening - the forklifts need to unload/load trucks and often a couple hours pass by between truck arrivals.
The forklifts do not seem to jam when they are at their home location, they are completely still. Also there are 15 forklifts in the model, so the fleet size shouldn't cause performance issues either. The simulation is using about 15-20% of the allocated memory.
Is this a natural consequence of using free-space transporters or is it possibly a mistake on my side? I tried switching the model time units from seconds to hours but it did not help significantly.
...ANSWER
Answered 2022-Mar-21 at 16:22Yes, these forklifts lower your computation speed a fair bit. They constantly re-evalulate stuff, even if not used.
If you do not need the specific capability of an advanced object (like a forklift), you should always revert to a simpler approach within a model.

I'm playing around with the scala-forklift library and wanted to test an idea by modifying the code in the library and example project.
This is how the project is structured:

ANSWER
Answered 2022-Feb-27 at 18:25Luis Miguel Mejía Suárez's comment worked perfectly and was the easier approach.
In the context of this project, all I had to do was:
- Append
-SNAPSHOTto the version in/version.sbt(should not be needed normally but for this project I had to do this) - Run
sbt publishLocalin the parent project.
After this, the example project (which already targets the -SNAPSHOT version) is able to pick up the locally built package.
QUESTION
I have 2 storages (called storageA & storageB) and I want to move an agent (pallet) from one to the other via forklifts. I have set up the following.
A pallet is created at a node and is moved to storageA via 'store'. This part works fine. The pallet is then moved to storageB via 'store1' after a delay. This is when the following error occurs:
...ANSWER
Answered 2022-Feb-16 at 07:35yeah unfortunately you can't do that as far as I know, the solution I use is the following, which is actually not a super robust solution... but has been ok in applications so far
- Place a retrieve block between your delay and your store1
- Use the agent you pick up as destination:
- on the on seize action of the retrieve block do:
agent.transporter=unit;
4.On the store1 block put the highest priority for the task
5. ON the store1 block use resource custom transporter choice: agent.transporter.equals(unit)
6. The dispatching policy should be nearest to the agent in store1, but doing all the above ensures that the resource continues doing the task no matter what... by only using the dispatch policy your model will work 99.999999% of the time... the problem occurs only if another task with higher priority occurs at the exact same time as the transporter is released in the retrieve block, which is rare, but can happen.
QUESTION
In AnyLogic 8, how do I create a Time Color Plot which has one row for each agent in a pool of agents?
As explained in an answer to this question, I can create a separate dataset for each row, and then have the Time Color Plot display one row for each dataset. But this requires hardcoding the number of datasets (and thus the number of agents), whereas I want to create a model with a variable number of agents and thus a variable number of rows in the Time Color Plot.
This AnyLogic cloud model includes a Time Color Plot where each forklift in a pool of agents has its own row in a Time Color Plot. Unfortunately, because it is a cloud model, I cannot download the model to investigate how it is built.
How do I create a Time Color Plot where each row corresponds to an agent in a pool of agents (like in that linked cloud model)?
...ANSWER
Answered 2021-Aug-03 at 08:55You can simply add the datasets programmatically using chart.addDataSet();
Here is the code for the model you referenced where the chart starts off empty (except for the color setup) and you simply add the bars during run time.
You can also remove them as needed.
QUESTION
I would like to use transporters in my model in various places (tugboats, forklifts, reach stackers, trucks, etc.). However, my model paths and animation can't be drawn to scale, detailed explanation in brackets below. Is there a way I can move the transporter from one node to another based on travel time (similar to what a movable resource can do), rather than speed and distance? The "Move By Transporter" block does not seem to allow this and I have not been able to find a solution online. Thank you for your help.
(Explanation on why I can't draw to scale: firstly, some destination locations (storage areas, etc.) are not known yet and will just be represented by a travel delay to get there, secondly, different areas of the model will be drawn to different scales, i.e. some network paths will represent a multiple kilometers and some network paths will only represent a few hundred meters, etc.)
...ANSWER
Answered 2022-Jan-31 at 05:24You can draw the paths to suit your animation and then simply set the speed of the transporter that gets seized to a speed so that the duration of the movement matches what you need it to be, and when the transporter gets released set the speed back to normal

I was trying to write a script that, when you submit a google form, it puts a pdf link to my Google Sheets. However, there seems to be some kind of error. I don't have any experience at all with Google Sheets, so I just copied it from some YouTube video and adjusted it a bit.
https://www.youtube.com/watch?v=EpZGvKIHmR8
The problem says:
TypeError: Cannot read property 'namedValues' of undefined (line 27, file "Code")
Can someone help me to understand the reason of this error?

This is not how onSubmit triggers work.
- Your function expects the parameter
e(event object). - As you can draw from the documentation, event objects like
namedValues,rangeorvaluesbecome available within a spreadsheet bound script on form submit. - To access those event objects, you need to bind a (installable form submit) trigger to your (form submit) event
- For this, follow the instrucitons in the documentation - depending on the editor version you are using
- Create a new
form submittrigger and bind it to the functionafterFormSubmit(e) - Do not try to run the function
afterFormSubmit(e)manually (if you do so - the event objectewill be empty since there was no form submit event) - When a new form submission has taken place, the function
afterFormSubmit(e)will fire automatically by the trigger.

I have a php array below and i want to know how to get number of companies who did a training course. Look below:
...ANSWER
Answered 2021-Apr-12 at 18:30Effectively you have a list of employees with their training listed in a comma separated list?
So basically you need to iterate through the list stripping out the information you require (company & training). Then every time you get a match you increment the matching data.
There are a few ways to do this the simplest would be to iterate through the results to create an array which looks something like...
