I am completely new to AnyLogic.
I am creating an airport simulation. I want to link an excel file with the flight schedule (departure time, check-in desk, gate number) so that the agents follow this flight schedule synchronously, so how do I do this?
The pedSource is linked to selectOutput5 where it will decide which check-in desk to go to according to their flight but unsure how to define the conditions with the excel database linked.
When creating the agents, you assign the parameters from the database. Please refer to this link: https://www.anylogic.com/blog/how-to-video-reading-agent-attributes-from-a-database/
Then you can set your condition in selectOutputOut block, such as agent.checkInDesk==1.

I'm trying to change the existing model in Anylogic (product delivery) and trying to move trucks to various locations. in manufacturing processes I add batch and hold to put 5 orders in the truck, but after I can't communicate with truck state chart and can't make it read the trigger (msg). I tried various methods but couldn't make it work. I'm new in anylogic and your help will be appreciated.
the first thing you should do is go to the truck agent, to the connections object, and verify if your message is being sent
Also to understand better how messages work, i suggest you watch the following video which is part of the course available at noorjax.teachable.com

I am using Anylogic for a simulation-modeling class, and I am not anylogic or coding smart. My last and only coding class was MatLab based about 16 yrs ago. I have a few questions about how to implement modeling concepts in a discrete model with anylogic.
How can I add/inject agents directly into a queue downstream from a source? I have tried adding an additional source to use the “Calls of inject() function,” but I am not sure how to implement it after selecting it ( example: what do I do after selecting the Calls of inject() function). I have the new source feeding directly into the queue where I want the inject.
How can I set the release of an agent to a defined schedule instead of a rate? Currently, I have my working model set to interarrival time. But I would like to set the agent release to a defined schedule. (example: agent-1 released at 120 seconds, agent-2 released at 150 seconds, agent-3 released at 270 seconds)
Any help would be greatly appreciated, especially if it can be written in a “explain to me like I am 5yrs old” format.
Question 1:
If you have a source connected directly to a queue, then when you call source.inject() an agent will be created at the source block and go to the queue. If you have 1 source with multiple possible destinations, then you will have to use select output blocks and some criteria to go from the source to the desired queue.
Since you mentioned not being a strong programmer, this probably wouldn't be for you, but I often find myself creating agents via add_population and then just adding them to an ArrayList until I am ready to pull them into the DES flow. Really, there are near infinite ways to control agent flow within AnyLogic.
Question 2:
Option a: Arrivals by "Arrival Table in Database" You can link an AnyLogic database table to Excel, and then the source block will just have an agent arrive based on that table.
Option b: Arrival Schedule - you could set this up manually within the development environment or load your schedule from a database. I prefer option a over option b given your brief description.
Option c: Read in data to variable and then write code to release based on next arrival time. 1,000s of ways to do this, but one example could be a list of doubles (your arrival times), set an event to delay until next arrival, call inject function, remove that arrival from the list. I think option a would be best for you, but given that AnyLogic allows you to add java code, there are no limits to how sophisticated you could make your arrival logic.
For 2) You could also use an event or a dynamic event. The action could be source.inject(1); and you can schedule them to your preferences with variables. Just be vigilant that you re-start the events if necessary.
There is a demo-model from AnyLogic for dynamic events.
I am simulating a hospital stay with anylogic, on multiple levels. Each level has its own staff, represented by different ResourcePool (doctor, nurses, OSS) I created the flowchart of the actions concerning the patient. Now I would like, at a specific time (lunch and dinner), the OSS do tour the patients.
How do I set up that all OSS of a ResourcePool go to the rooms?
I would like to create a very small parallel flowchart, with sieze, moveTo, delay and release.

Easiest way is to use the "Downtime" element to prescribe your resources to do some action, see image below:
Under the "task type" selection, you can send them to a separate flow chart using a "ResourceTaskStart" element and they will do what you put downstream of that (moveto, delay...). Make sure to finish that with a ResourceTaskEnd block.
PS: The "Downtime" block can easily be triggered via a schedule. Make sure to read the help on that block (and the ResourceTaskStart/End blocks) and study the example models that use those.
I'm working on a supply chain project with AnyLogic. In my model which is similar to product delivery example in AnyLogic examples, there are two agents which are Retailer and Fulfillment center. Both have their own vehicles. What I'm trying to do is to share vehicles so retailers and Fulfillment centers use the vehicles of each others. What I did is to create two Ressource Pool in each agent. So in the seize block as it shown below in picture, I added two ressource sets . In each statechart of each vehicle as it shown below and after delievering products, I informed my vehicle to go back to his initial location and in this case it can be Retailer or Fulfillment center. However after simulation, I got an error message in console that tells me that my agent which is the vehicle is trying to move to unknown source
If you put 2 ResourcePools into 2 agents, you have 4 pools in total. But you only want 1 shared pool, right?
Only add 1 ResourcePool to Main and use that from both agent's Seize elements. You will not be able to select the pool in the usual dropdown list (as there is no pool in either agent) but you can easily use the dynamic code to specify it. Note that the code below assumes both agents are embedded in Main:
I have a stock agent which is created in the end of my production line. My products are characterized by their model. I'm trying to create a logic to take out the products from this stock agent when they are to be delivered to the client. This delivery is controlled by an excel sheet and I'm taking the information through a SQL code. However, I was not able to find the right code to take out the products which are to be delivered. My agent population is called ProdutoStock and it's located in my main screen.
I have tried: Main.remove_ProdutoStock() but i couldn't figure out the arguments that i need for this function, since i have to take out of the agent a specific number of agents and also of a specific model.
So, I decided to create a wait block and use the free function to free the specific agents i wanted main.waiting_delivery.free() but i also can't figure out the necessary arguments for this function.
Would someone have any idea how I can take out of my agent/line the products that I need to deliver for my client (considering quality and also model)? This code is not being typed into my main screen.
the argument of the free method is the agent itself.
So you have to do main.waiting_delivery.free(yourAgent);
If you want to free the last agent that entered the wait block:
if(main.waiting_delivery.size()>0)
main.waiting_delivery.free(main.waiting_delivery.get(0));
If you want to free agents following a certain condition
List <YourAgent> theAgents=findAll(main.yourAgentPopulation,a->a.condition==true);
for(YourAgent a : theAgents){
main.waiting_delivery.free(a);
}
