So what about the AMS?
• Document-centric• Disconnected
Results in:• Duplication of data• Inconsistencies• Traceability impractical

Seem familiar?

A management system is a complex system

What if?
• Single information source• AMS elements connected• Multiple views of the elements and connections• Key documents an output
Overview of model-based systems engineering
“A construct or collection of different elements that together produce results
not obtainable by the elements alone”
- INCOSE

System concept
Systems engineering (SE) aims to:• understand the complete problem: lifecycle, context,
components and how to recognise a good solution• integrate work across disciplines and speciality groups• define stakeholder needs and system functionality early
in the system life cycle
“An interdisciplinary approach and means to enable the realization of
successful systems”
- INCOSE
AMS framework using a model-based approach | 21
Systems engineering
Model-based SE (MBSE) is:• The modern approach to SE• Used to capture information about the problem and
designed system solution• Used throughout the system life cycle by multiple
teams and disciplines• Used to produce system specifications and
documentation from the model
The model is essential, it is the “current collective
understanding”

Traceability is the heart of MBSE

Multiple views
MBSE is not a silver bulletrubbish in, rubbish out
andcomplete automation is
not possible, nor desirable, input and
review needed
AMS framework using a model-based approach | 25
Benefits of MBSE
Traceability• Links established and maintained as part of the
approach
Consistency• ‘Current collective understanding’• Internal consistency
Adaptability• Any number of views or documents can be
produced as snapshots of the model
Research project objectives and findings
How did we do?
AMS framework using a model-based approach | 27
Research aims
Develop a framework to:• capture an organisation’s asset management
information• produce a suite of artefacts, such as:
• Asset management policy• SAMP• AMPs• Role descriptions• Asset management maturity assessment
AMS framework using a model-based approach | 28
AMS concept model
• Greater focus on ‘operate & maintain’
• Connectivity between:• Objectives• Policy• Strategy• Execution
AMS framework using a model-based approach | 29
AMS model schema
• Developed a schema based on best practice MBSE to capture information relevant to the asset management system which can be used to produce the required outputs

Proposed application
A best practice Asset Management System
should be defined using an information model

Findings & further work
Initial findings• Framework can be built• Key outputs can be produced
Further work• Select appropriate system modelling tool• Populate and test the framework for a rail
organisation• Build in other requirements e.g. ONRSR
