Why do System Simulation?

Why do System Simulation?


NAFEMS wishes to commission an author to the publication “Why do System Simulation?”. This publication aims to delve into the role of system simulation and is envisioned as a resource that bridges the gap between theoretical knowledge and practical application.

Intended Readership

The primary audience for this publication includes mechanical engineers, team leaders and managers interested in broadening their understanding of system simulation across various engineering disciplines.


The publication is expected to provide a practical guide, with links to underlying theory for analysts, including (but not limited to) the following topics:

  • Introduction to system simulation (purpose, scope, significance, and value),
  • Types of systems and models,
  • Introduction to the concepts of Real Time Simulation, Model-in-the-Loop (MiL), Software-in-the-Loop (SiL), Hardware-in-the-Loop (HiL), co-simulation and Reduced Order Models, Digital Twins and Predictive Maintenance, FMU and FMI,
  • Best practices and applications showcasing models, results, and the value generated by the application of system simulation,
  • Regulatory and standardisation aspects, challenges and limitations, future trends.


The document should confirm to the standard NAFEMS publication template (provided upon contract award). The anticipated length of the publication is between 60-100 A5 pages.


The total cost is not expected to exceed £8000 (GBP), and it is expected that the document will be completed within 12 months from NAFEMS approval.

Guidance for Proposals

Each proposal should consist of:

  • The proposed structure of the document with the titles of the sections to be developed,
  • Work plan including milestones and interim deliveries for early review,
  • Cost,
  • The authors' credentials, curriculum vitae, etc. (Proposals from single authors and consortia will be considered.),
  • The PSE competencies that the publication is anticipated to address. Contact to obtain access.


All proposals should be sent to NAFEMS at to arrive no later than 1st of January 2025.
