sim

Discrete event simulation library, inspired by GPSS and SimPy.

Usage

import { Process, Sim, uniformInt, varExpo } from "https://deno.land/x/[email protected]/mod.ts";

const sim = new Sim();

function* agent(id: number): Process {
    console.log(`time ${sim.time}: agent ${id}, starting`);
    yield uniformInt(4, 8); // do something that takes between 4 and 8 units of time
    console.log(`time ${sim.time}: agent ${id}, finished first action`);
    yield uniformInt(2, 6);
    console.log(`time ${sim.time}: agent ${id}, finished`);
}

sim.generate(varExpo(1 / 5), agent); // generate one agent every 5 units of time
sim.run(30); // start the simulation, and run it for 30 units of time

Check the examples folder for other models.

Current capabilities

• Scheduling of events with simulated time
• Resources, with impatience
• Throttling
• Event interruption
• Basic analysis (multiple runs, ANOVA, etc.)
• Basic charts (using Vega-Lite)

TO-DO

• More examples
• Ability for processes to get more information about the simulated environment (resource stats, etc.)
