I am trying to figure out how to queue 3 material items which would then enter 3 different stations. Lets say the material items are named as (1,2,3). For the first station, it will accept 1 and then 2 and then 3. For the next station, it will accept 2 and then 3 and then 1. And for the final station, it will accept 3 first, and then 1 and finally 2.
So there will be a starting conveyor in which all three material items would be randomly generated, and the conveyor will branch out into 3 other conveyors containing the stations.
I am quite new to anylogic so any help would be much appreciated
New edit:
So what i am trying to accomplish here as you can see there are three conveyors which would converge to one final conveyor where the station is located. There are 3 sources, whereby source 1 would have MyAgent1 , source 2 have MyAgent2 and source 3 with MyAgent3. Before the material items ( MyAgent1, MyAgent2 and MyAgent3) arrives at the final conveyor, I want it to enter based on a specified order - ( MyAgent2 followed by MyAgent1 and finally MyAgent3). Each Myagent will enter individually and not in a group, and the process will repeat itself again.
I tried to utilize the queue block with agent.priority thinking that it will prioritize according to my preference but to no effect.
Im sorry for the lack of anylogic lingo as i am not that familiar with it, if there is any help it would be much appreciated and you may ask for more details. Thank you

It seems that you would need a custom station (or many) in which the items wait and are resorted to their destinations.
But beyond saying that I don't think it is possible to give you more details with this level of information

I've a problem with a simulation in anylogic.
I have an item (agent) that must be processed by a resource, the result of this service block is the starting object and two different documents which are processed in two separate offices and which at the end of the flow will have to be linked to the article in question.
I can't find a way to do this division into 3 different agents, or in general, to model this flow.
Thanks in advice
You can use 2 split blocks to generate 2 independent documents and connect them through a variable or link to agents... maybe each original agent has an id and the copies in the split block will have something like agent.id=original.id;
Then after, when the documents are processed you can check for which ones have the same id to merge them into an article...
but if you want to get more complicated, there's also the following option:
create 2 enter blocks (enter1 and enter2), one for each document. I will assume your documents correspond to 2 different agent types called Document1 and Document2
On each one of the agent types, you will add a link to agents in order to be able to connect the documents to each other. Read more on link to agents on the help documentation if you don't know what that is.
At the end of the service block, on the on exit action, you can do the following:
Document1 doc1=add_Document1();
Document2 doc2=add_Document2();
doc1.linkToDoc2.connectTo(doc2);
enter1.take(doc1);
enter2.take(doc2);
I don't know if your original agent has to be connected, but you would follow the same principle to do that.
Later, you can just check if the connected docs are completed in order to join them in an article again.
In Anylogic 8.5.1, I am doing a simulation for library evacuation, I have set and agent with Option-list that contains different types of users: students, organizers, graduates, and others. Also, I have set 'custom distribution' parameter to set the distribution values for each user. Until now, I have run the model and every thing is working well.
What I want is:
1. to use 'pedFlowStatistics' line in particular places (I can do this);
2. want to count the users that pass this line (I do not know how to do it);
3. then draw a chart to highlight the different number of users that passes that particular line space (I do not know how to do it).
I need help in the above situation, thanks in advance.
I do not have a Java background.
It's not possible to count based on conditions with pedFlowStatistics... you can only count the total pedestrians using:
pedFlowStatistics.countPeds(); // counts total number of pedestrians
pedFlowStatistics.traffic(); //shows the number of pedestrians per hour
You can use these functions directly in your chart.
But since you want to count based on conditions (the type of user they are), you will need to be smart about this and depending on your model, you will have to count pedestrians in a different place... or maybe use 2 ped go to blocks and count in between... it depends on your layout and model.
I was looking on VSTS, but I didn't found how to estimate our Tasks/users story in hours instead of Story point.
Is this possible?
I know the pro(and cons) of story points, buf for now our team want to move progressively with agile, and we don't want to start to estimate in story points.
Thank you!
Edit as requested, I currently use the agile template(but open to change)
Declare "One story point is equal to one hour" and use the existing field as-is.
TL;DR
Use the built-in scrum template
If you use the built-in Scrum template Tasks have Remaining Work and PBI's have Effort. Nothing says Remaing Work = hours or Effort = story points.
If you want to estimate your tasks in number of 4 hour work blocks it will take to complete you can do that, if you want to do it in hours you can do that. Same goes for effort you can put any number in there you want as long as you make sure everyone in your team understands what 1 or 5 or 10 means.
So if possible switch to the scrum template, your question is exactly the reason why these fields have a more generic name than Story Points or Remaining Hours in the scrum template. Added bonus is that your team can switch definition if they feel like some other number or unit suits your estimation process better.
This blog post makes a good comparison between the built-in different templates:

If you are an administrator in VSTS select the VSTS button at the top left of the screen. Then select then select the cog.
This will take you to a page where you can edit a number of settings. Select Process.
In the process window choose the process your project uses. You can see which one your project is using by the numbers on the right hand side of the process. Once you’ve found your process select it by clicking.
Then choose the work item type you wish to change. So in this instance user story.
Once in the task you want to change select add group and name the group want to add and select it's placement on the card.
When the group has been added select it and choose the ellipses (...). Then select Add Field. Customise the field to be either a new one of your choosing or choose a predefined one.
Once you have added this step repeat the process on this page to customise and style the task how you like. Once done navigate back to your project in VSTS and the changes will be applied
I'm am storing agents two deep in a single pallet rack with a rackStore block. When I take items out of the rack with rackStore it tries the take the agents at the back first and I get the error below saying it couldn't be picked as there are other agents in front of it.
Anyone know how I can pick from the front instead?
This is big fail in the AnyLogic Software and it is something they have to fix urgently. Since when it comes to deep positions, you have to control everything manually.
I will give you an example that is definitely not optimal on how to solve your particular question and it will be just a step for you to understand how to extend it to something more than this. Because even though this should be a very easy question, it is not. This will work only 2 racks with 2 levels deep, 1 level of height, and a unique row.
So this is the structure you would need:
Since I have no idea how long your products stay on the rack, I will assume something, which is that with the event, I will make the decision on wether getting or not a product from the rack every 5 seconds (this is absolutely arbitrary).
You will need a custom agent to store the deep position. I call the agent Box and I will have a population of boxes. Not in the picture that I also add agents to the custom population boxes.The box agent will have 2 variables: deep and position which will store the position and deep level of the agent in the rack (you will need also level and row if you have a more complex rack)
Now on the event, which runs cyclically every 5 seconds, I have the following action: (it activates if there is a box waiting, if there is a resource available and if there is no forklift moving a product to the pallet rack) I have to do this because I cannot know where the forklift is going to put the box until the box is already in the pallet rack. Then I check if a box is not behind another with the findFirst function and if everything ok, a box is sent to be picked.
if(wait.size()>0 && resourcePool.idle()>0 && rackStore.size()==0){
Box bx=findFirst(wait,b->b.deep==0);
if(bx!=null)
wait.free(bx);
}
On the rackStore exit I need to store the positions so in the "on exit" action, this code will help (you check if there is another box in the same position, and if there is, you update the value of the deep variable. Then you store the value of the position and deep of the new agent)
Box box=findFirst(wait,b->b.position==position);
if(box!=null){
box.deep++;
}
agent.deep=0;
agent.position=position;
Finally on the rackPick on exit action, once the product is picked and delivered, you update the deep value of the box that was behind it (if any)
Box bx2=findFirst(wait,b->b.position==agent.position);
if(bx2!=null){
bx2.deep--;
}
I know all this looks a bit crazy, but you have to create all the logic yourself when it comes to using deep levels...
I am making simple distribution center in Anylogic.I did make truck agent and i am able to move it from one gis point to another gis point.
But I want to load some other agents(Let's say banana agent) into my truck agent and then trucks start their journey(if truck is full of banana).How can i do this?
I hope you have already solved your problem from almost a year ago. However, since there is no specific answer, I'll leave it here for anyone who might get stuck with the same problem.
Anylogic's Process Modelling Library (PML) has an element called Pickup and its opposite, Dropoff. This is used to do exactly what you asked: to load some element into a transporter (either a truck, a forklift, or even a person).
To use the block as you asked you would need a topology like in the picture:
The Queue elements are necessary to hold elements until the pickup occurs.
The Pickup element might pick elements in three modes:
While a given condition is True;
An exact amount (if available);
All available agents.
I'm assuming all trucks must be completely filled up to its maximum capacity. Hence, the chosen mode will be the second one where the exact amount will be TruckCapacity, a parameter of agent Truck.
The selected mode picks up agents (in this case Bananas) up to the desired amount. However, if nothing is available or the present amount is inferior to the desired, the native behavior of the Pickup block is to allow the container element to simply go through it and pick only what's available.
To prevent such behavior, I've created a restricted area where only 1 Truck can be at a time. Additionally, the Hold block WaitFullyLoaded (set to initially blocked) forces the container agent Truck to be fully loaded. Whenever a Banana enters the Queue waitTruck, a verification is performed to check if 1 Truck can be filled. If so, allows passage for that one truck:
if(self.size()/TruckCapacity>=1){
WaitFullyLoaded.unblock();
}
To block WaitFullyLoaded again, when the truck passes through the restrictedAreaEnd block, it performs WaitFullyLoaded.block();
The main idea is this. However, many features can be added and changed.
Hope this helps,
