A Simple Discrete-Event Simulation: Part 67
Today I began implementing the capability of handling different types of entities. The two main aspects of this problem are how to assign properties to an entity and how those properties affect how an entity is processed by different parts … Continue reading
A Simple Discrete-Event Simulation: Part 64
As I’ve been developing and experimenting with JavaScript over the last year-plus I’ve been more interested in showing my experience in simulation, graphics, and analysis than I have been with cross-browser- or backward-compatibility. If it ran on my phone (iPhone … Continue reading
A Simple Discrete-Event Simulation: Part 56
I the process of working off some of the TODO: items I have sprinkled through the code I ended up fleshing out the model verification function. It is called after everything is defined but before the model runs. I haven’t … Continue reading
A Simple Discrete-Event Simulation: Part 55
Today I got a lot of updates into the mechanism for forwarding entities from one component to another. The changes were chiefly made to the Queue and Process components with some supplementary changes to the Path component. The first change … Continue reading
A Simple Discrete-Event Simulation: Part 43
Today I went through and cleaned up each of the component definitions in the process of implementing the ability to rerun the simulation without having to refresh the browser page. Beyond just neatening up the code for each component I … Continue reading
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 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
Approach Contexts for Potential Solutions
As I’ve been pondering different aspects of my engagement framework, the management environments I’ve experienced, and the nature of the solutions I’ve helped create or that I’ve learned about through other means, it occurs to me that potential solutions are … Continue reading

Bringing Order to Collections and Systems
I’ve recently been putting together a bunch of related thoughts about how I do some parts of systems analysis and design. They involve bringing order to collections of items, data, actions, and ideas. I’ve written about one of the ideas … Continue reading
Advanced Manufacturing Process Integration Ideas
I’ve seen a lot of different things over the years and they cannot help but suggest possibilities for ways things can be done in a more streamlined, integrated way. Of particular interest to me has been the many novel ways … Continue reading
