@mingsterism/simulator v1.2.2

Process Simulator

This TypeScript-based simulator models a business process using event-driven architecture. It's designed to simulate various processes based on provided templates and handles parallel and exclusive gateway nodes, including approval/decision nodes, which are essential components in business process modeling.

Setup

To set up the simulator, follow these steps:

1. Install the dependencies:

   npm install

2. For testing, select one of the four different process templates from example_processes.ts, and run the tests to simulate the business process:

   npm run test

Features

• Event-Driven Architecture: Uses an event-driven approach to model the flow of the business process.
• Gateway Nodes: Supports both parallel and exclusive gateway nodes (including approval/decision nodes) to replicate complex business logic.
• Loopback Handling: Throws an error if a loopback scenario is detected; currently unable to simulate processes with loopback scenarios.

Structure

The Simulator is located in the src/ directory. It contains the following files:

• main.ts: Contains the process simulator.
• utils.ts: Contains the helper functions of the simulator.
• types.ts: Contains data types used in the simulator and helper functions.
• example_processes.ts: Contains four different types of process templates for testing.
• test.ts: A playground for simulating different process templates.

Configuration

You can configure the Simulator by modifying the files in the src/ directory. The core function is simulateNode in utils.ts, which is responsible for simulating the metrics of a single node and recursively processing subsequent nodes to provide a live simulation of the entire process. By adjusting the parameters and logic within this function, you can tailor the simulation to fit specific business process requirements.
