Citation preview
Integrated Vehicle Health Management (IVHM)An enabler to the ‘servitization’ of products within the UK manufacturing sector – a model approach
Lou ReddingDoctoral ConsortiumAnnual Conference of the Prognostics and Health Management SocietySan Diego, USASept 28th – Oct 1st, 2009

• IVHM a Definition• Significant Benefits• Research Aim and Objectives• Research Framework – Current and Future• Questions
IVHM – A Definition
“..the capture of [asset] condition, both current and predicted, and the use of this information to enhance operational decisions, support actions, and subsequent business performance”

Research Aim
“To map high value IVHM applications in use within the UK and then to create a decision tool that will enable the evaluation of potential benefits of new and alternative applications”.
Research Objectives – slide 1 of 4
1. To Identify and understand the level of awareness within UK manufacturing companies of the principles of IVHM. [Survey]
2. To understand the extent to which IVHM has been, or is being, adopted as part of a competitive strategy within UK mainstream manufacturing• Who are the stakeholders driving IVHM?• How is IVHM data used within organisational
infrastructures? [Literature, Survey, Case Studies]
Research Objectives – slide 2 of 4
3. To identify from those companies stating use or awareness, the specific capabilities required to develop IVHM applications.
• Company characteristics• Core competences• Product Characteristics [Case Studies]
Research Objectives – slide 3 of 4
4. To identify examples of success/failure within UK manufacturing [Literature & Case Studies]
5. To identify enablers/inhibitors to IVHM application and adoption. [Literature & Case Exemplars]
(e.g. risk, cost, functionality, strategic position)
6. To identify means of quantification of benefits.• Are existing financial models valid?• Are existing operational and commercial models
valid? [Literature & Case Exemplars]
Research ObjectivesSlide 4 of 4
7. To construct a verified and validated simulation model or decision framework that will inform UK based manufacturing companies based upon organisational “pull”.

• Audit trail
Gaps Identified to date.
Gap 1. There are few cited examples of IVHM existing
outside the aerospace and military sectors
Gap 2. The are no documented case studies within the
literature of failed applications
Gap 3. There is a need for a generic frame work/tool
that enables the potential user to assess the
technical, commercial, financial, and business
case for introducing IVHM outside of aerospace
and military sectors
Gaps Identified to date
Gap 4. A decision process is required to identify the
level of IVHM adoption to be applied to an
asset.
Gap 5. Identification of additional KPI’s better suited to
emerging business models facilitated by
‘servitization’ and the introduction of IVHM
Gap 6. All the literature is technology ‘pushed’, but to
what extent is demand being customer
‘pulled’?
Gaps Identified to date.
Gap 7. All models and solutions have been designed
and published by engineers for engineers.
[little or no contributions have been made
outside of this group – business community]
Gap 8. Of the cost/benefit models, there are potential
difficulties with the time scale of ‘whole’ life PSS
solutions. [How do you assess twenty plus year
cash flows in volatile markets]..... Requires a
financial NOT engineering appraisal.
Gaps Identified to Date
Gap 9. Non aerospace data mining methodologies are
required in order to construct algorithms.....
[We are at the start of the ‘s’ curve]
1. Bibliographic data base containing 1300 papers from academic journals, conference papers, reports and proceedings. [Complete]
2. State of the art literature review to form Chapter 2 of the thesis [1st Draft Complete and Submitted]
3. Potential for Journal Paper December 2009.
4. Gap Analysis within the literature.
Stage 1:- Deliverables
Stage 2 - Addressing Objective 1 and Part of Objective 2
• Understanding of the level of awareness of the principles of IVHM within mainstream UK manufacturing
• To start to understand the level at which the adoption of IVHM is being used to inform competitive strategy

Population at each stage of Data Framing
Framing the data set
304 Companies after review of Web sites
1837 Companies who had a turnover ≥ 10,000,000 GBP
77710
Companies who
had a UK based manufacturing
operation
2,752,710 Companies based in the UK
Framing of Target Population for Survey
Only 0.01% (304) companies listed are UK manufacturers with a turnover ≥ 10,000,000 GBP, and have products support IVHM
Only 0.07% of companies listed are product manufacturers with a turnover which is ≥ 10,000,000 GBP
Only 2.8% (77710) of those companies listed are manufacturing products
There are 2752710 trading companies within the UK listed on FAME on 15-05-09
