The Integrated Modelling Environment (IME)
hierarchy
The Integrated Modelling Environment (IME) will allow the simulation of the product hierarchy at the design and prototype stage

Challenge:
One of the great challenges in complex system development is the control of the design properties throughout the lifecycle. Modelling plays a key role in this activity but our current approaches do not adequately support product integration – in particular we fail to provide proper traceability of design properties throughout the product breakdown structure, nor do we adequately manage the impact of uncertainties in modelling activity throughout the lifecycle.
Vision:
To enhance the performance of products and reduce costs by directed improvements in modelling achieved through consideration of the uncertainties and sensitivities inherent in product properties
Business benefits to BAE SYSTEMS
  • Increase in understanding of modelling capability
    • Lead to a more extensive and effective use of modelling
  • More effective systems engineering
    • Bringing together disparate sections of design community
    • Increase awareness of interrelationships in the product hierarchy
  • Wider dissemination of best practices
    • Storage and traceability of design practices should encourage design reuse
  • More effective targeting of modelling capability (specifically in the development area)
    • Allows identification of strengths and weaknesses in existing capabilities
Modelling framework research aim
To obtain an understanding of areas in which modelling is used by developing an integrated modelling environment (IME) that can be fully deployed within BAE SYSTEMS

This will assist system and vehicle designers to optimise design-to-cost and allow a measurement of overall fleet performance by considering system properties throughout the design hierarchy

We will do this by:
  • Implementing a more efficient & effective use of modelling capability
  • Permitting a consistent record of how systems function
  • Creating a traceable record of the design decisions used
  • Encouraging reuse of previous design decisions in new systems
Impacts of the IME approach
  • Improved integrated modelling architecture with resulting improvement in design & model traceability and model re-use.
  • Ability to determine which models need to be improved or developed to obtain the required levels of fidelity to ensure that the customer requirements will be met with a suitably high level of confidence earlier in the design and at minimum cost.
  • Obtain an understanding of the costs of achieving given levels of dependability.
  • Aid and derive the benefits of trade-off across systems and vehicle design.
  • Increased visibility and navigability of complex integrated modelling structures.
  • Development of a more “fit-for-purpose” modelling capability.
  • Aid to non-fragmented modelling, whole product trade-off and reduced re-work.
