I created a variable, called labour cost. And I want this to increase, for example by 40 every 900s that the simulation is run. Can this be done?
Add an event with the following properties:
Instead of variable, use the name of your total cost variable of course.
Anything can be done with AnyLogic ;)
Use a recurring event that triggers this code every 900s:
myVariable+=40;
This is very basic so I also suggest you dig into all step-by-step tutorials that come with the help :)

I'd like to know a very simple function of the software Anylogic: I have to set different delay times for different agents in a model, but the software let me see only one boxe and there's no possibilities to specificate what kind of delay time I prefer for every agents. How could I do? Thank you
I tried with some code of Java script but I think that scripture could be available only for the section "Actions" in the different boxes
This is one of the most basic functionalities so check the tutorials as well, but here goes:
Add a parameter 'myParameter' in your agent type of type double.
Give the agents different values for that parameter (cab be dine in the source or where ever you instantiate your agents)
In the delay block code section, use 'agent.myParameter' to access and apply that agent-specific duration.
I am a newbie to anylogic simulations. In my project, I want to take out queue size at every time step from a service block and create a dataset. Similarly, I also want to take out the mean queue size from the same after every replication and create a dataset of that as well. Can anyone help me with how to do it?
Welcome to SOF and AnyLogic. Best post separate issues for separate questions, see this intro to SOF for AnyLogic users.
But for now:
I want to take out queue size at every time step from a service block and create a dataset.
Use a cyclic event that calls myDataSet.add(myServiceBlock.queue.size())
I also want to take out the mean queue size from the same after every replication and create a dataset of that as well.
In your experiment, add a DataSet myMeanResults. In the "On Simulation end" code box of your experiment, call myMeanResults.add(root.myDataSet.getYMean())
Make sure your Datasets can keep enough values!
Also, always check the AnyLogic help and example models. Very often, these basics are covered there already. Else, tell us what you already tried :)
Dear KQL master/ expert,
I've been trying to find the most effective (elegant) solution to achieve what I'm trying to do. I'd like to hear from the community, thank you.
Situation:
Currently we have an anomaly detection rules named "Process execution frequency anomaly" running every hour, and generated a lot of false-positives
We would like to tune the analytic rule by changing "threshold" value in series_decompose_anomalies.
We would like to simulate the analytic rule running various different settings, to see how much incident it would be generated.
Issue/ Things I tried:
The idea was to simulate "as if" the analytic rule is running every hour 7 days back for example. Similar to "Result simulation" section.
I have been able to create a simulation in Workbooks for simple analytic rules, by adding make-series command at the end of the KQL line. However, for this specific anomaly detection rules, I haven't been able to recreate it. Most likely because the data is produced by series_decompose_anomalies function in memory.
Question:
Is it doable?
Did I approach this incorrectly?
Is it best to change the settings, and then do an evaluation in the next 30 days ?
Thank you for your thoughts and suggestions.
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 modeling ticket system with various SLA. The model must contain several service blocks with different reaction time ( from 2 to 32 hours). In the service block only working hours should be taken into account. So in the service block timeout should stop when non-workong hours and on the weekend. Could you please kindly tell me how i can realize it?
Thank you very much in advance!
I can think of two answers, one simplified but works in many cases, the other more advanced and probably more accurate:
Simplified approach: I would set the model in hours and keep everything running as is without any stop. So, at the end of the simulation, if the total time is 100 hours and you know that you have 8 hours/day with 5 days/week, then you'd know the total duration is 2.5 weeks. Of course, this might have limitations or might become more complex later on if you want day-specific actions (e.g. you want to differentiate between Monday, Tuesday, etc.)
Advanced more accurate approach: Create resources whose capacities are defined by schedule and assigned them to your services. Create a schedule and specify the working hours in that schedule. Check the below link to learn more about schedules. I call this the more advanced approach because you need to make sure the schedule is defined correctly and make sure all elements in the model are properly controlled (e.g. non-service blocks such as source, delays, etc.).
https://help.anylogic.com/topic/com.anylogic.help/html/data/schedule.html?resultof=%22%73%63%68%65%64%75%6c%65%73%22%20%22%73%63%68%65%64%75%6c%22%20
I personally would use the first approach if the model is rather simple and modeling working hours is enough for analysis. Otherwise, I'd go for option 2.
Finally, another option I'd like to highlight is the "suspend/resume" functions. I am only adding this because you asked "how to stop timeout". So these functions specifically stop and resume timeout. But you'll need to define the times at which they are executed (through an event for example).
