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 trying to simulate a manufacturing assembly process, where material items are processed following an unique line. In the quality control stations, when a failure is detected, the object is sent to the repair area (by a truckpallet) and, when it is repaired, the same resource takes it and puts it at the start of the line. Until this point, I already programmed it.
The problem is the following: when it is a repaired object, is has to follow the same conveyor but with no stops in the stations. The object must enter a station and leave it, with no delays (as the works related with the stations have already been made).
I thought the best would be to consider the difference (repaired vs. not repaired) in the Agent, but then I can't work with it in the Main agent... I have also tried alternative solutions, for example defining variables in each station 1 and consider that in the stations delays and in the following station:
triangular( 109.1*delay_bec, delaytime_bec*delay_bec, 307.6*delay_bec)
Actions - in finished process:
if(delay_bec==0){
delay_headers=0;
delay_bec=1;}
But nothing worked... Any help?

This is actually the correct approach. You need to create a custom agent type, give in a boolean variable isRepaired (or similar) and then in the delay you can dynamically adjust the duration using that characteristic:
agent.isRepaired ? 0. : 100
This will delay normal agents by 100 time units and repaired agents not at all.
Obviously, you must make sure that the agents flowing through the flow blocks are of your custom agent type (see the help how to do that)
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 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);
}
I am interested in capturing the time a particular material handler(AGV in my case) spends at a particular node before it is released. Is there a way to do so?
This works in general, since I don't know anything about your model (there are many other ways depending on what you are doing):
Create a variable and make it equal to time when your AGV arrives to the node:
timeWhenArrivesToNode=time();
Create another variable and make it equal to the amount of time it spent in that node... This code should be executed at the moment when the AGV leaves the node:
timesWhenItIsReleased=time()-timeWhenArrivesToNode;
Of course the answer will have the time units of your model.
I am working on a simple application that I need to be run as a service and report gps position every 3 minutes. I already have a working example based on the tutorial, but still have the followin doubts.
The starting of the service GPS1.Start(5*60*1000, 0)
Says first parameter is time lapse, and 2nd parameter is distance difference, How is determined, based on prior position ?
If I want to do what I stated before and I am scheduling / starting service every 3 minutes, this means I will need to ask a GPS1.Start(0,0) to get latest fix? what would be the gain to use the parameters?
I trying in a NexusOne and the Time object comes with local time, I have to do this to make it UTC but this is a tweak to the code. Is this a standard or could It change based on Phone model ? hora=DateTime.Date(Location1.Time + 6*DateTime.TicksPerHour)
thanks
If you are only interested in a single fix each time then you should pass 0, 0. These values affect the frequency of subsequent events.
You can find the time zone with the code posted here: GetTimeZone
