DTaaS for Users

User Guide

This guide is for users of the DTaaS platform. You need access to a live installation of the DTaaS platform. The simplest option is the workspace localhost installation scenario.

These user-specific Slides and this conceptual presentation explain the concepts behind composable digital twins in the DTaaS platform.

Motivation

A central question for Digital Twin (DT) software platforms is how to support collaborative activities:

  • Building digital twins (DTs)
  • Using DTs independently
  • Sharing DTs with other users
  • Providing existing DTs as a service to other users

DT software platforms must also offer:

  • Support for DT lifecycle management
  • Scalability through flexible convention over configuration

Existing Approaches

Recent literature proposes several solutions to these challenges, including:

  • Focus on data from Physical Twins (PTs) for analysis, diagnosis, and planning
  • Sharing DT assets across upstream and downstream stakeholders
  • Evaluating different models of PT
  • DevOps methodologies for Cyber Physical Systems (CPS)
  • Scaling DT execution and ensemble management of related DTs
  • Support for PT product lifecycle

The DTaaS Approach

The DTaaS platform follows these principles[1]:

  • Support for transition from existing workflows to DT frameworks
  • Creation of DTs from reusable assets
  • Enabling users to share DT assets
  • Offering DTs as a Service
  • Integration of DTs with external software systems
  • Separation of configurations for independent DT components
