Today I made a few basic changes. Instead of placing all elements (components and entities) that contain discrete-event simulation features into the setOfEntities array I created a setOfComponents array and placed the components in there, instead. This allows me to … Continue reading →

The Exit component is always available to accept any entities sent to it. It doesn’t have to store any entities but only has to keep track of when they “arrive,” which means they are leaving the model. The Exit component … Continue reading →

Today I added a Process component. This component is meant to represent a process that takes some amount of time to complete. The time could be zero and there can be other side effects, which usually involve changing properties of … Continue reading →

Today I added a queue component, so the entities are generated by the Arrivals component, inserted at the Entry component, and forwarded to the Queue component. At this point the processes are all instantaneous, but they will get more interesting … Continue reading →

Today I made a few tweaks, but the main thing was adding an Entry component and a means of moving entities through the model. Remembering that the entities are entirely passive, the components must be able to hand entities off … Continue reading →

Having sorted out the internal reference issues in JavaScript I could go ahead and post the next update to the model framework. In this iteration the entities are completely passive, which means that the newly created entities are generated using … Continue reading →

The solution is that there is no solution. The simplest thing to do is to ensure that the values are updated by hand whenever they need to be drawn. I’ve included a method called assignDisplayValues to the arrivals component. It … Continue reading →

While making the changes I described yesterday I ran into a problem where a long chain of (what I expected to be) references didn’t return the results I was expecting. Somewhere in the chain of references something appears to be … Continue reading →
