I would like to set a random break time of 2 hours everyday for each resource unit within a resource pool. I was able to add a schedule for break times set to 2 hours from 12 pm - 2 pm, however, I would like that time interval to be randomly selected for each resource everyday. Can anyone help me with this? I'm pretty new to AnyLogic.
Thanks!

instead of using the break setting forcing you to define a schedule (which is not random), use the "failures/repairs" setting instead and apply randomness as below. Note that this may cause more than 1 break in a day, but on average, it will be 1 a day for 2 hrs. Note also that failures behave exactly like breaks functionally.
You can, of course, also apply your own custom ResourceTask, name it "breaks" and set it up there.
I will give you a solution that will ensure that your resources take 1 break per day:
Create a variable in your resource agent called timeForNextBreak with initial value uniform(0,22) ... since they take 2 hours break, you want this to happen between 00:00 and 22:00, this also assumes your simulation starts at 00:00
Creat a variable in your resource agent called timeRemainingInDay with initial value 24, this also assumes your simulation starts at 00:00
create a custom resource task called randomBreak and use it in your resource pool
In your randomBreak resource task, complete the data as follows.

I've got 3 different product types of agent, which each go it's individual path within the fabric. How can i measure the average time the product type spends in the system?
My logic looks like this , and i wanted to implement the measurement in the first service, like this:, it will be completed in the last service like this :
Now I get some really high numbers, which are absolutely wrong. The process itself works fine, if you run the measurement with the code "//agent.enteredSystemP1 = time()", you will get a mean of 24 minutes, per product. But how can i get the mean per product type?
Just use the same if-elseif-else distinction in the 2nd service block as well.
Currently, any agent leaving the system adds time to any systemTimeDistribution
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).
I've currently got this Cron expression that I'm using to trigger a process in UiPath Orchestrator:
0 0 15 21W * ? *
Runs on the closest working day to the 21st of each month at 3pm.
However I need it to run on the next working day at 3pm if the 21st is a non working day.
Tried searching for an answer and nothing quite fit the brief.
I used this website to build my expression (which is a great tool) but it only had an option for 'nearest day' and not next working day given a specific day of month: https://www.freeformatter.com/cron-expression-generator-quartz.html
As you don't need the nearest day, you can't use the functionality of Orchestrator cronjob. I would recommend creating a wrapper process as follows:
Create a new process, let's call it StartJobByCheckingDate
Now create a trigger that starts StartJobByCheckingDate each day at 3pm
So that process is now your manager of your desired process
Now we need to check if it is the 21th day
Here you have different ways to solve it
You could create a DataTable or even a file in the StartJobByCheckingDate process, that contains all the different days where your desired process should be fired (but this is very manual, you might not want to update this every year, so this might not be the smartest but the easiest solution)
The other idea is to check if the current day is the 21th day. If so check if it is Saturday/Sunday (non-working day).
If true: you could now create a empty dummy file somewhere that tracks that the 21th was a non-working day, and the next day you check that file existing, if it exists you check the current day to be a working day, and if so you delete the file again and start your desired process
If false: just start your desired process directly
I think 2. idea would be that best. Sure you have 365 jobs runs/year. But when you keep that helper process smart this will just be seconds.
Another idea instead of using the dummy file, would be to use Entities. Smarter but need some more time to get familiar with.
We have (had) the exact same issue. Since UiPath doesn't offer a feasible solution out of the box, we will work around the restriction using the following strategy: We trigger the actual job daily, considering a custom-built, static NonWorkingDay-list that will just suppress the execution of the robot every day we don't want it to run.
These steps are needed:
Get a list with of all known bank holidays, saturdays and sundays until 2053 or so...
Build a the static exclusion-list using a script that does something like this (pseudocode. I will update the answer once we have actually implemented the solution):
1. get all valid execution dates
loop through every 28th of the month until end of 2053
if the date is in the bankHolidayList then
loop until the next bankDay is found
add it to the list of valid ExecutionDates
else
add the date to the validExecutionDate-list
2. build exclusion-list
loop through every day until end of 2053
if the date is not in the validExecutionDate-list
add it to the exclusionDate-list
Format the csv accordingly and upload it to the orchestrator tenant as a NonWorkingDay-List
Update your trigger to run daily at your desired time, using the uploaded NonWorkDay-Calendar
While the accepted answer will surely work as well, we prefered to go with this approach because having a separate robot that does nothing but executing a UiPath trigger just doesn't seem right to me. With this approach we have no additional code that we potentially need to maintain.
In my oppinion not having a solution for this concern out of the box is a lack of feature that UiPath will (hopefully) fix until end of 2053 ;-)
Cheers
You can configure your trigger to launch oftener, then manage dates at init of your process, but you must set up a list of "holydays" or check in some way.
Also you can use the calendar option of orchestrator (+info)
I want to set the warm-up period in AnyLogic Personal Learning Edition. I searched for the warm-up period place in AnyLogic, but I couldn't find any thing about the warm-up period.
Is there a warm up period in Anylogic or something like this?
There is no default warm-up setting as it would not make sense given the vast flexibility of the tool and user needs.
It is easy, however, to set it up yourself. As usual, there are many different options, here is one:
create a variable v_WarmupDuration on Main, set it to whatever many time units you need
any data object you want to only record after the warmup period, ensure it only captures data if time() > v_WarmupDuration.
Events can have a custom initial time which you can use v_WarmupDuration for.
Functions that log data can only do so if time() > v_WarmupDuration, and so on.
Alternatively, log all your data as normal but add time stamps to them. Then, you can
Creating a warmup variable works fine for metrics you create yourself.
But if you want to use the built in functionality like histograms created from timeMeasureStart and timeMeasureEnd blocks in Anylogic, you will also need to add an extra select option so e.g. assuming you set v_WarmupDuration to 60 minutes, then you need a select block with a decision on false that goes straight to sink block or the next element after the timeMeasureEnd.
Condition if true: time(MINUTE) > v_warmupDuration
That way, the warmup period will not accumulate into the dataset of the timeMeasureEnd.
If you want to set this as a parmeter to an experiment, then ...
Add a variable to the experiment page off the screen e.g. v_warmupMins
Add a control like a slider on the experiment page and link to the variable v_warmupMins
Add a parameter to hold the warmup time in the Main canvas e.g. p_warmupMins
On the experiment properties, set the parameter p_warmupMins = v_warmupMins
to programmatically add this time onto the StopTime, add this to the Before Simulation Runs
getEngine().setStopTime( getEngine().getStopTime(MINUTE) + v_warmupMins );
Now when i run experiment with slider set to 60 mins, it adds 60 mins onto the stoptime and runs the experiment without accumulating metrics until that time has passed.
Hope that helps.
In our app, we have an ability to schedule tasks and we converting this functionality to Quartz. One of the problems that I have is scheduling recurring task that should run, for example, every third day.
The cron expression that I had in mind first of all is:
0 37 18 */3 * ? *
But what this will do, is execute that job on 1,4,7, etc... Which is fine, assuming that I want to start from the first day of the month. However, how to deal with this issue if I need to start from 11th?
I could do something like this:
0 37 18 11/3 * ? *
But, in this case, I will always miss all the days before the 11th.
Also, when the time comes for the next month, the expectation that the day of the month will now be different (on one month the job executed on 1st, and on another it could be on 2/3), but based on the cron above it will restart on the same day (e.g. 1st).
I could, of course, count using hours, but then I will have an issue with day light saving?
What is the correct way to organize it? Or am I missing something?
UPDATE
Possible solution is to use simple trigger, as per http://www.quartz-scheduler.org/documentation/quartz-2.1.x/cookbook/BiDailyTrigger.
But in this case, how do I resolve DST problem?
Thanks,
