A Simple Discrete-Event Simulation: Part 91

Posted on May 23, 2018 by R.P. Churchill

I started thinking about the design of processes that require resources and realized there are a lot of ways I could go with this, so I thought I’d back up and think it through in writing. Let’s begin with a … Continue reading →

A Simple Discrete-Event Simulation: Part 90

Posted on May 22, 2018 by R.P. Churchill

This evening I attended the DC IIBA Meetup on the subject of process mapping, which is obviously an area in which I have some experience. Since I’ve reached a natural break in writing about pure business analysis subjects I’m going … Continue reading →

JavaScript Inheritance: A Form of Composition

Posted on April 5, 2017 by R.P. Churchill

Lectures 53 through 56 of JavaScript: Understanding the Weird Parts discuss more about the creation and manipulation of objects under the hood. I’d seen different aspects of this material previously, which gave me a different take on how to build … Continue reading →

A Simple Discrete-Event Simulation: Part 89

Posted on March 29, 2017 by R.P. Churchill

Direct link for mobile devices. I was walking a few miles in the nice weather this evening when two possible solutions popped into my head for the DisplayGroup drag problem I had in the simulation app (where the pointer arrow … Continue reading →

A Simple Discrete-Event Simulation: Part 88

Posted on March 9, 2017 by R.P. Churchill

Direct link for mobile devices. Today I updated the code to define DisplayGroups for all non-Path components, which means the internal data for each component will become visible when the relevant component is clicked. Moreover, each visible DisplayGroup object can … Continue reading →

A Simple Discrete-Event Simulation: Part 87

Posted on March 8, 2017 by R.P. Churchill

Today I connected the display of the DisplayGroup objects to the component selection event. That is, if you click on a component it brings up that component’s DisplayGroup object. This process involves several steps. First, the location on the canvas … Continue reading →

A Simple Discrete-Event Simulation: Part 86

Posted on March 7, 2017 by R.P. Churchill

I was working to add the next behavior when I discovered that things that used to work no longer did. After a bit of digging I realized that the problem was trying to handle click events separately from mouseup and … Continue reading →

A Simple Discrete-Event Simulation: Part 85

Posted on March 6, 2017 by R.P. Churchill

Direct link for mobile devices. Today I made the selection action work using touch events in addition to the mouse click event. The touch mechanism in JavaScript for mobile browsers does not current have a click counterpart so we have … Continue reading →

A Simple Discrete-Event Simulation: Part 84

Posted on March 2, 2017 by R.P. Churchill

Today I implemented the ability to select graphic elements using a mouse click. This involves sensing the mouse click event and its location, variations of which we’ve already visited, and identifying the graphic element on that part of the screen. … Continue reading →

A Simple Discrete-Event Simulation: Part 83

Posted on March 1, 2017 by R.P. Churchill

Direct link for mobile devices. Now that I have the chance to return to the Discrete-Event Simulation project the next item to work on is touch events. I had already implemented the ability to scroll the 2D display horizontally and … Continue reading →
