In 2016 the Royal Navy’s new Type 45 Destroyers bought from BAE Systems were reported as breaking down in the gulf because the “water was too hot”. Want to avoid a similar calamity? Read on… If you have ever been asked to come up with some reliability requirements then you have probably thought about defining … More Three Cardinal Sins of Reliability Requirements
Designing the Logic for Waterloo The first step when constructing any simulation is to decide where the boundary conditions of the simulation are. What do I mean by boundary conditions? This is where we decide where to start and where to stop modelling. After all, Waterloo does not exist in isolation. We could continue … More Modelling the Capacity of London Waterloo
The Coffee Machine What was described in my previous post with the clock was an example of a process. In this post we will discuss resources – the second key component of making discrete-event simulations. If a process is a series of actions or events, a resource is something of value which processes interact with. … More Modelling Resources and Queues in Simpy
Despite what you may have heard, simulation is as much an art as a science. There are infinite possibilities of how models can be constructed. Don’t let that put you off though – instead see it as an opportunity to really engage the analytical side of your brain. Simulations are abstractions of real life. Deciding … More Introduction to Discrete-Event Simulation in Python
