## A Simple Discrete-Event Simulation: Part 17

Today I added an animation to the simulation. There are a lot of things that could be said about this, and I’ll go into just a few of them today. At this point I wanted to get some kind of … Continue reading

## A Simple Discrete-Event Simulation: Part 16

So far I’ve been discussing ways of generating arrivals according to a specific schedule. There’s another way to do it, based on the Poisson distribution. From Wikipedia: The Poisson distribution is an appropriate model if the following assumptions are true. … Continue reading

## A Simple Discrete-Event Simulation: Part 15

Today I wanted to describe a few additional methods for generating arrivals over a given time span. Last week we divided the arrivals evenly over the span without placing any at the beginning or end. The next possibility is generating … Continue reading

## A Simple Discrete-Event Simulation: Part 14

Today I modified the entry component so it creates new entities according to a supplied schedule. This can be made as complex as we’d like but let’s keep it simple for now: the input parameters are the duration of each … Continue reading

## A Simple Discrete-Event Simulation: Part 13

Today I wanted to streamline the code in the activate method for the entities that apply the advance command. I started by breaking the code in the series of if statements out into separate methods, which at least makes things … Continue reading

## A Simple Discrete-Event Simulation: Part 12

Today I wanted to start constructing an Entry component. I created a very simple on that generates modeled entities are regular, defined intervals over the duration of the simulation run. Here’s the relevant code.

This generates the following output. … Continue reading

## A Simple Discrete-Event Simulation: Part 11

Now that we have a couple of basic mechanisms in place for building discrete-event simulations let’s apply them to some actual components we can use to represent something real. A very simple system might consist of the following four components … Continue reading

## Art, Waste, and a Rumination on Economics

I’m going to table the work on the discrete-event simulation today in order to discuss a public art critique I attended last night. The gallery featured a few pieces of the works of two artists, Jessica Burnam and Eric Celarier, … Continue reading
