Interactive Schedule Reduction Model

Prototype application to demonstrate browser- and service-based modeling and simulation methods as discussed in [1]. The constituent design flow model is drawn from past work [2] and available here (file path: UTRC_CODA.r5.2.zip\UTRC_CODA\Design_Flow\Design Flow Modeling\META System Dynamics Model v3) as a Vensim file released under a Creative Commons 2.5 license.

This demonstration shows both standalone and service-based tools to execute and visualize model results.

Prerequisites:

• Git client
• Node.js
• MongoDB

Installation/start-up instructions:

1. Clone this repository
2. Install dependent Node modules (run command npm install from project root)
3. Create data directory (recommended to make in project root, e.g. mkdir data)
4. Start MongoDB service (run command mongod --dbpath /path/to/data from MongoDB bin folder)
5. Start Node execution (run command npm start from project root)
6. Open a web browser to localhost:3000
