Introduction

• Intended impact of Modelling & Simulation:

1. Reduction of cost by reducing/eliminating physical prototypes

2. Reduction of time-to-market by using readily reconfigurable models

simulations

3. Improved design maturity by extensive use of simulations

• Actual Impact arises over time

• It takes time to produce reliable models

• However, engineering the models for re-use addresses 1 & 2

• Engineering the models and conducting simulations creates

knowledge

• Knowledge thus created informs design decision-making

• Informed decision-making addresses 3, and contributes to 1 & 2.

Intended impact takes place over time; benefits may not be fully realised at the first application

Overview: Working Definitions

• Experimentation

• Discovering the “true” requirements

• Discovering the possible behaviours (time-based & event-based)

• Discovering inter-dependencies amongst the system elements

• Design

• “Sizing” the system of interest, e.g.

• Form: addresses geometry

• Fit: addresses interfaces

• Function: addresses behaviours

• Test – Verification

• Confirming that the system, at a

given design stage, conforms to

its allocated requirements

Experimentation (open questions)

8 October 2013 Matlab EXPO 2013 - Model-Based Design Session

• Exemplar questions:

• When I apply <this> stimuli what response do I get?

• What stimuli generates <this> response?

• What are the desired behaviours?

• Under what context are these behaviours exhibited?

• What interconnections can assure these behaviours?

Example: Library of model components

Example: Visualisation & Analysis

Knowledge acquisition is an iterative process; new knowledge raises new questions.

Design

8 October 2013 Matlab EXPO 2013 - Model-Based Design Session

Modelling as a “day-job”

System designers developing the models as

part of the design

No need for separate “over-the-wall” modelling

Modelling is an integral

part of Design

Knowledge acquired by the modelling & simulation team members is disseminated, retained and used within the design team

Testing – Verification (closed questions)

8 October 2013 Matlab EXPO 2013 - Model-Based Design Session

• Exemplar questions:

• When I apply <this> stimuli I shall get <that> response?

• When I apply <this> stimuli I shall NOT get <that> response?

• … within a prescribed context

Hardware in the loop

Pilot in the loop

… including training

The simulation models encapsulate the behaviours of the “system under design”; therefore approximate the system behaviours.

CONGA Project Background

Configuration Optimisation for Next Generation Aircraft

• A 2-year project under the Technology Strategy Board’s “Building

the UK Leadership in Aerodynamics” competition

• Led by Airbus, CONGA has 6 other partners:

• Rolls Royce, EADS-UK, Aircraft Research Association, Eurostep,

MSC Software and Cranfield University (School of Engineering and

School of Applied Science)

• The main purpose of CONGA is to develop a proof-of-concept

for a “System for Creating Valued* Aircraft Configurations” using

Set-Based Design Methodology.

8 October 2013 Matlab EXPO 2013 - Model-Based Design Session

* Valued by multiple stakeholders, e.g. Society, Government, Customers & Manufacturers

Summary

• Impacts of Modelling & Simulation

• The intended impact takes place over time; benefits may not be fully

realised at the first application

• It takes time to produce reliable models; their reuse contributes to

further time- and cost-savings

• Modelling and Simulations creates knowledge that informs design

decision-making leading to design maturity.

• Modelling & Simulation as an integral part of design

• Knowledge acquired by the modelling & simulation team members is

disseminated, retained and used within the design team

• Reuse design models for testing

• The simulation models encapsulate the behaviours of the “system

under design”; therefore approximate the system behaviours.

• Not aspects of a system can be modelled!

Summary

• Challenges for Modelling & Simulation

• Collaboration is about working together not just exchanging

• Interoperability: specially of data, information and rationale

• “Platform” neutral

• Standardisation: data model and methods for sharing the

information (MoSSEC: Modelling & Simulation collaboration in a

Systems Engineering Context)

• Multi-level Models & Simulations

• Reliable, early analyses for assessing insertion of new

technologies

• Built on scientific principles – abstracted to the level needed

depending on the design questions

• Needed for assessing a large number of design options.
