Simulation of a action or occurrence detected by the program that may be handled by the program. Typically events are handled synchronously with the program flow, that is, the program has one or more dedicated places where events are handled, frequently an event loop. Typical sources of events include the user (who presses a key on the keyboard, in other words, through a keystroke). Another source is a hardware device such as a timer. Any program can trigger its own custom set of events as well, e.g. to communicate the completion of a task. A computer program that changes its behavior in response to events is said to be event-driven, often with the goal of being interactive.

anylogic error: Not unqiue database value

In an Anylogic discrete event model, I am trying to set an arrival rate and how many agents per arrival based on a database table I created. The table includes a column for the date and time a material came in, and then a unique code and order…

Why do we need stochasticity in deterministic simulations?

Assuming the world were deterministic, why would we still need to introduce stochasticity into our simulations?

How to use stopDelay(agent) on AnyLogic

I am generating multiple agents at the source. I would like to let them wait until some event. I am trying to access the "delay.stopDelay(agent)" however it requires an agent as a parameter. How should I proceed?

Request entity from Anyogic Process Block and wait until it's available if there is not currently one

I'm trying to emulate what QUEST does when a buffer is queried for a certain Part. In there if the part is not in the buffer the request is left pending and if a Part arrives to the buffer it's released to the machine requesting it. I have also seen…

Java Discrete Event Simulation, how to signal a class of a different object

I have a class named Neuron, and when the Neuron object fires, it signals all of the objects of class Synapse to fire. I'm unsure how to send a signal to the Synapse from class Neuron, can anyone explain?

R simmer resource not dropping arrival when capacity --> 0

In my simulation, certain resources are on a capacity schedule, which alternates between 0 and 1 based on the time of day. If a resource cannot complete its task by the time its capacity goes to zero, the arrival should be dropped, wait a short…
