Concept Modeling
A concept model, or conceptual model, is an abstract representation of an organization, process, system, or product. It relates the nouns and verbs and other categorizations within and between elements. It can take any arbitrary form, in contrast with the … Continue reading
Components of a Solution
I wanted to define some terms and provide some context in preparation for the next few posts. Specifically, I’m describing the components of a solution. A process model is a model of a system that either does exist or will … Continue reading
Simulation: Continuing Yesterday’s Analysis
Yesterday I analyzed some of the considerations involved in modeling a section of a petrochemical refining process, namely that of hydrodesulfurization. That is adding hydrogen to hydrocarbons containing sulfur in the presence of a catalyst at an elevated temperature so … Continue reading

Simulations: What Gets Modeled And What Doesn’t
When I’m not flogging away at code these days I’m thinking about continuous simulations and the details that get modeled within them. Specifically I’ve been reading about and thinking about operations in petrochemical refineries, and even more specifically certain classes … Continue reading

What Drives The Scale Of A Business Or Simulation System?
The scale of a business or simulation (continuous or discrete-event) system can be driven by a number of factors. Scale can be measured in terms of CPU cycles, communication bandwidth, disk storage, dynamic memory usage, power consumption, and perhaps other … Continue reading

Discrete-Event Simulation vs. Business Logic
I wanted to continue yesterday’s discussion by describing some differences between discrete-event simulations and systems that might be implemented to carry out business logic. The first diagram below shows a model of privately owned vehicles and commercial vehicles passing through … Continue reading

Handling Complex Wait..Until Conditions
Last Wednesday I discussed some of the internal workings of discrete-event simulations. I should also mention that all of these discussions are based on a program running in a single thread that is trying to coordinate many activities. There are … Continue reading

Business Process Model and Notation (BPMN 2.0)
Today I was able to complete a thorough power-read of the book Real Life BPMN by Jakob Freund and Bernd Rücker. I’ve performed discovery on, analyzed, characterized, automated, modeled, simulated, documented, controlled, and improved various kinds of customer processes more … Continue reading
