Introduction

This site provides information about the United Kingdom Ministry of Defence (MODUK) activity in Synthetic Environments, Modelling and Simulation (SEMS).

Modelling and Simulation (M&S) has been widely used for many years to support many defence activities. Examples include the use of mathematical models during Operational Analysis to assess options for new equipments, force structures and doctrine and tactics. Physical models (such as wind tunnels and ship tanks and mock-ups) have been used to refine equipment design, whilst the advent of analogue computers led to the development of simulators for the training of aircrew and other personnel.

Advances in technology and the use of digital computers have lead to a major expansion in the power of models and simulation. A significant further development has been the ability to link different models and simulations to form Synthetic Environments, enabling models, simulations, real equipment and people to interact to provide a more complete representation of the battlespace.

Today SEMS can provide:

• A comprehensive representation of the natural environment and the forces and equipments which operate within it.
• The ability to explore and visualise interactions and hence improve understanding of the 'real world'.
• A flexible and relatively low cost (compared to live trials or prototypes) way to explore issues and proposed solutions ahead of major investment and commitment.
• Enhanced training opportunities, free from environmental constraints including interaction with other co-operating or opposing participants.
• A through-life approach to applications such as equipment acquisition.
• Reuse and consistency of SEMS across defence applications.

SEMS are playing an increasing role in helping to deliver UK Defence Capability. To learn more, please navigate this site using the links on the left.
