I'm trying to model a production sequence in anylogic where orders should come in with an interarrival time of normal(8,105) seconds. These orders should come in every week day between 11 am and 2 pm (3 hour window).
I tried to implement this with the Schedule block in anylogic but this only allows me to define a rate per hour. Is there a way to do this with interarrival time?
Also the agents that arrive at 1:59 pm should also be processed even if it takes until after 2 pm. Is there a way to calculate the mean working time per day (the time from the generation of the first agent by the source block until the last generated agent enters the sink block)?
Thank you all in advance!
I would use the getHour() function and dispose of the agents if hour is not between 11 and 14. And inside the source you don't need to do anything special. If it even arrives at 11.59 pm it will be processed.

I have created a discrete simulation model for our production processes in which the capacity, output, etc. should be simulated for the coming year. The model works, but I have a problem with measuring the process time. Our production only works from 7 a.m. to 3 p.m. Is there a way to set the TimeMeasureStart and TimeMeasureEnd block so that the time is only measured during the shift?
As a simplified example with a TimeMeasureStart, a service and a TimeMeasureEnd block:
The agent passes TimeMeasureStart at 2:30 p.m. and immediately enters the service block. The service time is 2 hours. The worker starts the service and goes home at 3:00 p.m. The agent waits in the service block from 3:00 p.m. to 7:00 a.m. At 7 a.m. the worker continues the service (until 8:30 a.m.). As soon as it is finished, the agent passes the TimeMeasureEnd block. The result is currently a process time of 18 hours. However, I only want to measure the time that is worked, so that I get 2 hours as the process time.
Is there a possibility to set / program the TimeMeasureStart / TimeMeasureEnd blocks accordingly so that the waiting time is not included?
My first suggestion would be to ensure that you really need calendar time, why not just run the model in hours and every hour is a working hour... then you don't need to shift schedule.
But often for reporting or having different shift patterns within your model requires you to need calendar time as the basis.
Here is a simple solution: Simply record the time a resource was seized through your own local variables.
You need to add two double variables to your agent 1 for last start and 1 for the cumulative time
previousServiceStart and cummServiceTime
and then save the times in the resource pool using the On seize and On release code
I casted the agent to my custom agent using the (MyAgent)agent code, so that I can access the variables
I need to create a trigger on daily basis between 8:30 and 6:00 with 30 minutes interval in azure data factory. can any of u please help me with steps to create?
Please follow my configuration as below:
It would be triggered every day at the specific time.
One little issue: It will be triggered at 18:30 because the limitation of configuration.You could just set a if-condition activity before all of your stuffs to judge if it is 18:30,then just leave the pipeline.
I am trying to write a periodic cron task for celery which should execute every hour from Tuesday 12pm to Wednesday 12 pm. That is a 24 hour period but spans two different days. Is it possible to schedule this as a single task like
#periodic_task(run_every=crontab(<an expression equivalent to stated above>))
At the moment I am writing two tasks: one with decorator:
crontab(minute='0',hour='12-23',day_of_week='tue') and another with
crontab(minute='0',hour='0-11',day_of_week='wed')
Some examples are given here
Thanks
Unfortunately the two specifications you've created cannot be consolidated into the same rule. The only real solution (less than ideal in most scenarios) that I can think of is to change the timezone under which Celery is executing using CELERY_TIMEZONE. +/-12 hours from the timezone you currently have configured with Celery would do the trick, though there very obviously could be other ramifications to doing this.
I'm trying to create a cron expression that will trigger a job according to the time I get, and every X minutes. both start/end time and the minutes intervals are parametrs I get from the user. for example:
start time: 09:15
end time: 19:35
minutes interval: 15
I want the job to start at 09:15 and to be triggred every 15 minutes, so the last job will actually be at 19:30 (because it can't be after 19:35).
my problem is that I dont know how to include the minutes of the start/end time..
How is it possible to create this kind of expression?
Thank's In advance.
I don't think that it is possible to meet your requirements in a single cron expression, as each time component (hours/minutes/seconds etc) is handled independently.
Perhaps the simplest approach would be to have a trigger for running every 15 minutes, and enable/disable this trigger at 09:15 and 19:35 (e.g. using additional triggers).
Alternatively you could have a trigger fire every 15 minutes, and procedural logic attached to this trigger which checks if the current time is between 09:15 and 19:35 before doing any work.
You don't need CRON, simple trigger will do. Check out Lesson 5: SimpleTrigger. This should work for your situation:
trigger = newTrigger()
.startAt(nineFifteen)
.endAt(nineteenThirtyFive)
.withSchedule(simpleSchedule().withIntervalInMinutes(15))
.forJob(someJob)
.build();
I am accessing an API hosted by Mashery with the following rate limit:
5 calls per second
10,000 calls per day
Does that imply that I can make 10,000 requests at 6:00PM, and then make another 10,000 requests at midnight? Or, does it mean I can only make 10,000 requests within any 24-hour period?
For example, does it mean that if I make 10,000 requests between 6:00PM one day, and 6:00PM the next, that I have to wait until 6:00:01PM before I can make another request. And then, at most I can make requests at the same rate I made the day prior (as the 24-hour period continuously shifts)?
I apologize if this is off-topic. I have a support request in for clarification, but I don't think they'll get back to me any time soon, and I figured that someone here would be familiar with the limits.
The limit is set per Calendar date and resets every midnight GMT time.
So for example if you made 10,000 calls at 6pm pacific (which is 2am GMT) you would have to wait 22 hours until 4pm pacific (which is midnight GMT) until you can start using your next batch of 10,000 daily calls.
Hope that answers your question.
Thanks,
