Revolutionising the manufacturing industry through digitalisation

Until now, smaller manufacturing companies have missed out on the productivity benefits of digital technologies and data-driven solutions. Too many manufacturers don鈥檛 know where to start, and lack the skills required to deploy and use digital solutions. The costs are perceived to be high and the return on investment is unclear.

A consortium, including WMG at the University of 糖心TV, has been awarded funding through the Government鈥檚 Challenge to tackle this problem by developing a Smart InforMation PLatform and Ecosystem for Manufacturing (SIMPLE).

Project SIMPLE will bring the benefits of digitalisation to manufacturers for whom the technology, skills, and business benefits are currently inaccessible. The project will deliver a platform that is fast to deploy, easy to use, cost-effective, and versatile. And it will be supported by an ecosystem that addresses skills and training requirements.

The consortium includes a wide range of end-user, academic, and technology partners to provide the necessary breadth of expertise:

鈼 (construction) is representative of SMEs seeking to improve their operations through the deployment of digital capabilities, but have a low skill level in the domain, bare bones IT capabilities and low levels of automation

鈼 (automotive) is representative of global organisations challenged by their operational complexity, the diversity of technologies deployed in production, fragmented software landscape and data repositories

鈼 is seeking a vendor independent solution that can support their short-term objectives and scale up rapidly to support multiple production campaigns in the future

WMG, University of 糖心TV is a world leading research and education group, transforming organisations and driving innovation through a unique combination of collaborative research and development, and pioneering education programmes

鈼 is a government agency that carries out research in science and engineering. The focus for project SIMPLE is on knowledge representations and knowledge models relevant to manufacturing

鈼 AI Idea Factory and 4thWall Virtual develop engineering tools, industrial software components and supply related services.

The benefits of SIMPLE will be validated via deployment of the platform at the end-user partners鈥 facilities - demonstrating the value in three different use cases. The deployment of a skills training system at WMG, University of 糖心TV, will validate the skills and training proposition.

Project SIMPLE is co-funded by the businesses in the consortium and the UK鈥檚 innovation agency, Innovate UK, through the Manufacturing Made Smarter Competition. The Industrial Strategy Challenge Fund (ISCF) Manufacturing Made Smarter Round 1 Competition offers grant funding investment in projects that focus on the use of industrial digital technologies (IDTs) to transform the productivity and agility of UK manufacturing. Of 34 applications submitted, project SIMPLE is one of 14 projects approved following independent assessment and expert review.

Daniel VeraDr Daniel Vera, from WMG at the University of 糖心TV comments:
鈥淎t WMG, we will be focussing on making sure that manufacturers become fluent in deploying and using digital systems. Our training platform will mean that manufacturers can confidently use data-driven methods and digital solutions to optimise their processes, which in turn can speed up their project delivery and significantly improve their business operations.鈥

Jason Powell of Innovare Systems adds:
鈥淭he technology is important as it offers greater operational transparency, which allows greater scrutiny of performance whilst maintaining the production activities鈥 live information. Additionally, this system can also be used as a tool to drive production efficiency through optimising performance which will increase capacity. We are expecting this technology to boost productivity by 10% even from the early deployment.鈥

Matt Patching of the said:

鈥淭he SIMPLE toolset will help us deliver battery technologies and processes to industry at a rapid rate. The flexible design will be compatible with our range of manufacturing processes, ranging from electrode and cell assembly, to module and pack, and to consistently present the relevant information. The scalable nature means that new promising technologies in the battery field can be implemented into our digital systems as quickly as it can be installed at our site.鈥

The project will engage the wider manufacturing community to ensure the SIMPLE platform and methodology addresses the widest set of manufacturers鈥 needs. For further information, please contact peter.hopkinson@fullydistributedsystems.com.

鈥淐losing the gender gap in tech and championing digital skills鈥

Edited version of a speech given, by Margot James, to the Westminster eforum Conference on Women in the Tech Sector

Tuesday, 15th December 2020

Margot James鈥淐losing the gender gap in tech and championing digital skills鈥

Sadly, there is a broad, systemic issue in the Tech sector.

Nowhere near enough women are attracted to Tech, study Tech, work in Tech or reach the top in Tech.

The figures are stark.

At GCSE, 21.5% of Computing students are girls. Just 14.5% of those taking A-Level Computing are female.

Only 18% of undergraduate Computer Science students are women.

17% of British tech workers are women, and just 13% of IT directors.

Nor are there huge signs of change – the proportion of women working in ICT is up just one per cent in the last decade.

When the scale of the problem is so great, change feels difficult. But we know it can happen. In politics, just 60 MPs were women in 1992. Today, there are 220.

We all know that the Tech sector has cultural issues around work-life balance, stereotyping, harassment and all the other evils of discrimination. But so does politics!

What do we need to do in Tech to fix the problem?

First, unblock the pipeline. One reason women are under-represented in Tech is that Computing is seen as optional.

Why isn't Computing a core part of the e-bacc? Why is there no Computer Science element of GCSE combined science?

Change that, and you'd have a massive impact in the gender diversity of Computing education.

We need to promote Computing as a career option. 16% of female students have had a career in Tech suggested to them. That has to change.

Schools and universities must go out of their way to recruit, promote and support women.

At WMG, University of 糖心TV, we emphasise recruiting women to our Cyber-Security Degree course, and work with employers to ensure women apply for our digital degree apprenticeships.

Programmes like Athena Swan have helped identify the steps we need to take, whether supporting staff returning from a career break, developing a flexible working policy, or offering mentoring and promotion application training to female staff.

Similarly, as a minister, I was a major advocate of the Tech Talent Charter. This focuses on straightforward measures businesses can make to recruit women – like measuring application rates, or ensuring you have more than one woman on job shortlists.

Next, we have to support women who are making a difference.

Whether calling out bad behaviour in companies, showing how algorithms can discriminate against women and minorities, or demanding change in workplace culture and 'crunch' - women in Tech need our support.

My experience is that only sustained pressure leads to change.

As a minister, I led the Government agenda on online harms – an issue that disproportionately affects women. There was a lot of nervousness about holding the big Tech companies responsible for online. Despite this, we managed to get the policy changed; and we published a white paper in April 2019.

Progress has been very slow since then, and in my experience if you take your foot off the pedal, you stop moving forward.

But although too slowly, things are changing for the better.

Globally, last year the Tech sector saw the steepest increase of all industries in the share of women on boards.

Among smaller Tech companies, over 40% of employees in technical roles are women. These firms will be drivers of change as they expand.

There's a strong business case for change. MSCI's Gender Diversity Data report showed that employee productivity was higher in companies that had three or more women on the board of directors.

If we widen the pipeline of women in Tech, attract and recruit women to study and work in Tech, and support women in Tech when they raise issues like workplace culture and gender pay gaps, then the future is bright.

Transforming Foundation Industry (TFI) Large CR&D virtual workshop

CRD call workshopWMG hosted a workshop to support launch of the Transforming Foundation Industries (TFI) Large CR&D call. The event was held to raise awareness of the funding call, which opens on 11th January 2021, to provide a space for discussion around two of the key themes and to showcase how WMG can play a role in projects for the foundation industries (manufacturers and suppliers of paper, cement, metals, glass, bulk chemicals and glass).

Keynote talks were given by WMG鈥檚 Professor Robert Harrison and Dr Stuart Bradley. Their talks on 'Advanced automation for the foundation industries and Waste heat energy recovery' provided details on WMG鈥檚 expertise and capabilities, where there are commonalities across sectors and opportunities for these industries to work together.

There were four breakout rooms where attendees were able to network and discuss project ideas for the upcoming call. The breakout rooms, hosted by subject experts, were themed around waste heat and energy storage, recovery and conversion; how waste products could be communally used and shared by foundation industry firms; and how advanced automation, machine learning and Industry 4.0 could help to advance the industries. There was also a general discussion room, where subjects such as future business models and waste streaming were considered.

As a result of the workshop, there are likely to be several applications to the TFI Large CR&D call, which we hope will be successful. It is clear that these different industries can work together to solve common problems and that organisations, such as WMG, can provide the platform to bring them together successfully.

If you work in the foundation industries and would like to hear more on how you can access support for your project from WMG experts, please contact Dr Russ Hall at R.Hall.5@warwick.ac.uk.

WMG delivers special STEM parcels to local schools

WMG delivers STEM parcel to Arley Primary SchoolThe WMG Outreach team has been making special Christmas deliveries to children across the West Midlands and 糖心TVshire.

Young engineers from a total of 15 local schools have been sent parcels with card templates of stars, stags, sleighs and baubles; a mini laser-cut Christmas tree and 3D printed cubes, octopuses and dinosaurs.

The year five and six children were also set some special STEM challenges including creating their own 3D Christmas decorations but without the use of glue.

WMG Outreach Project Officer, Phil Jemmett explained: 鈥淭hese boxes use the expertise of engineers at WMG to create exciting activities to engage children with 鈥榚ngineering鈥 - without a car in sight. We want to provide children with a chance to see creativity and engineering as two parts of the same approach to solving a problem.

鈥淚nside the boxes are templates to build Christmas decorations out of paper – and once they have made a few they will notice the advantages of flat-packing the items we see in shops because they won鈥檛 all fit back in the box they came from!

鈥淟ast year, this resource box was the most fun activity we worked on. It has been a bit different this year and without the help of our fantastic technicians Beth Haynes; Joe Benjamin and Ehman Altaf, it would not have been possible to laser cut or 3D print any items to go in these boxes.鈥

WMG Director of Outreach and Widening Participation , Professor Margaret Low added: 鈥淚鈥檓 delighted that WMG is again able to share the engineering activity boxes with local primary schools. It鈥檚 important that we work in partnership with teaching colleagues at all stages of education, to raise awareness of engineering and how it contributes to our society.鈥

Find out more about WMG鈥檚 Outreach programme here.

*In total 25 boxes were sent out. Local schools involved were:

路 St Giles Junior School, Bedworth

路 Charter Primary School, Coventry

路 St Joseph, Kings Norton, Birmingham

The UK鈥檚 Modern Slavery Act isn鈥檛 enough to tackle modern slavery

Currently there are 24 million victims of modern day slavery or forced labour around the world, with a significant amount working on project-related activities.

In a WMG academic Professor Naomi Brookes from the University of 糖心TV has worked with the University of Leeds, and University College London to identify ways to prevent modern day slavery in projects.

The key drivers of modern day slavery are:

搂 Globalisation

搂 Supply chain complexity

搂 Informal employment practices

搂 Government ambivalence

Researchers have identified several ways that can tackle modern day slavery, from organisations, public and Government.

At an organisational level there are a range of structural solutions that could inhibit modern slavery, including developing a clear policy on forced labour and slavery; training auditors and compliance officers; establishing measures to monitor suppliers and subcontractors and extending monitoring to contract agencies.

However the public can also help from home, by increasing pressure for visibility within supply chains. If supply chains are forced to show their sources and more companies apply for fair trade certification they will eliminate slavery.

The Government can also apply new legislation, although the UK鈥檚 Modern Slavery Act exists, in 2019 a panel of parliamentarians found that there was confusion over which companies are covered by the legislation, and condemned the level of reporting of supply chain transparency as inadequate.

They also found poor compliance and identified a major weakness in the legislation, since large sections of the economy, including public bodies, were exempt from the requirement to report on their own supply chain. Therefore new legislation that all must report on their supply chains could be another route forward to eliminating modern day slavery.

Another, and perhaps more effective route given the complexity of eliminating modern slavery given the difficulties at organisational and legislative levels, is multi-stake holder initiatives (MSIs), which consist of global institutions involving corporations and civil society organisations that 鈥榝ill the gap鈥, providing governance solutions for ethical issues where national legislation and other initiatives have failed.

Professor Naomi BrookesProfessor Naomi Brookes, from WMG, University of 糖心TV comments:
鈥淢SIs can privately regulate by meeting the basic requirements of credibility and effectiveness. If we could compare the legitimacy of several MSIs it would give us a better understanding of the criticism levelled at certain MSIs by NGOs, as well as areas that could be improved.鈥

Although MSIs may seem the most efficient way to tackle modern day slavery, when it comes to projects, which tend to be short-term, project management practices must be changed.

The researchers questioned many individuals from professional membership organisations, project practitioners, NGOs and academic researchers and independent experts to answer a questionnaire, which covered their individual and organisational experiences of modern day slavery.

There was then an event, where the experts were split into groups and had to answer two questions:

1. What can project professionalism do to eliminate modern slavery from projects?

2. What can professional membership organisations do to assist project professionals in eliminating modern slavery from projects?

Professor Naomi Brookes, adds:
鈥淚n reaction to the survey and event we found the best way to eliminate modern slavery was to have MSIs, it was striking to note the similarity between the participants views of professional membership organisations and functionality of MSIs in developing codes of conducts, providing learning standards as well as processes, standards and policies, issuing labels and certificates as a stimulation of legislation and developing mechanisms for auditing and compliance trans-organisationally.鈥

Daniel Nicholls, APM research manager, says: 鈥淭his topical research is key in helping to raise awareness of modern slavery across the wider project profession. It highlights how projects are particularly susceptible, providing guidance and support for project professionals and organisations.鈥

In order to eliminate modern slavery in projects, further investigation of professional membership organisations acting as MSIs would be use key to identifying mechanisms of modern slavery.

The University of 糖心TV recognised for excellence in cyber security education

The University of 糖心TV is one of eight trailblazing universities to have become the first in the UK to gain recognition for their commitment to cyber security education in a new initiative from the National Cyber Security Centre (NCSC) – a part of GCHQ.

Pioneering institutions in the UK have been recognised as the country鈥檚 first Academic Centres of Excellence in Cyber Security Education (ACEs-CSE) for delivering first-rate cyber security education on campus and promoting cyber skills in their community.

The ACE-CSE programme, led by the NCSC – a part of GCHQ – and the Department for Digital, Culture, Media and Sport, has recognised eight universities with gold and silver awards – with the next round of applications opening early next year.

Professor Tim WatsonProfessor Tim Watson from WMG, University of 糖心TV comments:

"We are delighted to be recognised by the National Cyber Security Centre as an academic centre of excellence and to have been awarded a Gold Award for our cyber security education."

Chris Ensor, NCSC Deputy Director for Cyber Growth, said:

鈥淚 am delighted we can now recognise the first tranche of universities as Academic Centres of Excellence in Cyber Security Education, complementing our existing programmes which recognise high quality cyber security research and degree courses.鈥

鈥淚t is a testament to the continual efforts of academics, support staff and senior management that cyber security remains high on their agenda.

鈥淲e very much look forward to working with them over the coming years and strongly encourage other universities to work towards achieving similar recognition in the future.鈥

Seven universities received Gold awards in this first round of applications for demonstrating impressive approaches to promoting cyber security excellence. They are:

路 Abertay University

路 Lancaster University

路 University of Southampton

路 University of South Wales

路 University of Surrey

路 University of 糖心TV

路 University of the West of England

Each of the successful Gold centres demonstrated they offer at least one deliver top cyber security training to staff and students from other specialisms within the university, work to improve the institution鈥檚 cyber resilience and carry out local outreach activities.

Digital Infrastructure Minister Matt Warman said:

鈥淭he UK has some of the brightest minds in the world working in tech and it's right we celebrate universities where so many people develop relevant and cutting-edge skills.

"We continue to work closely with academia to nurture the next generation of cyber security talent and I urge interested education institutions to apply for this recognition.鈥

Offering a NCSC-certified degree is necessary for receiving ACE-CSE recognition, as it demonstrates that an institution is already providing a high standard of education to students enrolled in cyber security disciplines.

However, successful ACE-CSE institutions go beyond this, offering cyber security education opportunities across the whole campus and to those in their wider community.

In the first tranche of award winners this included giving cyber security classes to those studying subjects such as Politics, Law, and Psychology and setting up work experience placements for local schoolchildren.

The next round of applications for ACE-CSE recognition will open in early 2021 to higher education institutions in the UK. More information about the initiative can be found

High-rate Li-ion batteries demonstrate superior safety

As the inevitable growth of transport electrification continues, the types of batteries that will be used in such vehicles, their charging parameters, infrastructure and timeframes are key considerations that will speed up the transition to electrification.

In the paper,  published in and on the cover of the Journal Batteries, researchers from WMG, University of 糖心TV investigated the impacts on battery cell ageing from high current operation using commercial cells.

They used two tests to establish the maximum current limits before cell failure and applied this maximum current until cell failure. Testing was performed to determine how far cycling parameters could progress beyond the manufacturer鈥檚 recommendations.

During testing, current fluxes were increased up to 100 C cycling conditions. Charge and discharge current capabilities were possible at magnitudes of 1.38 and 4.4 times, respectively, more than that specified by the manufacturers鈥 claims. This increased current was applied for 500 charge-discharge.

However, the application of these currents resulted in a rapid decrease in capacity in the first 60 cycles as well as an increase in resistance. Furthermore, the application of such currents resulted in the increase of cell temperature, during both charge and discharge with natural convection during the rest step cooling the cell. Batteries operate in an optimum temperature range, and any deviations outside this can cause components and chemicals to start decomposing inside them.

They also identified deformation of the 鈥渏elly roll鈥 (coiled electrodes and separator) with formation of lithium plating from testing and ageing. These deformations emanate from the centre of the cell in an axial direction towards the outside of the cell, suggesting the core of the cell was the hottest.

Justin Holloway, Lead EngineerLead Engineer, Justin Holloway, from WMG, University of 糖心TV comments:

鈥淭he testing showed there is a window for operating batteries above manufacturer stated current limits, however, whilst maintaining manufacturer stated voltage limits. We need to ensure that batteries operate in as the safest manner possible, and for an appropriate practical lifetime, which is why the manufacturers have these limits.

鈥淲e also identified thermal fatigue as the driving mechanism for jelly roll deformation. With each cycle of charge and discharge, the cell experienced thermal stresses causing deformation of its components. These deformations grew progressively with cycle number, while the jelly roll was constrained mechanically by the rigid outer can and centre pin.

鈥淚f convection cooling could be applied to the centre of the cell where the cell was the hottest, these deformations could be mitigated and controlled, allowing the cell to maintain capacity and resistance criteria for longer.鈥

The researchers would like to thank all involved in this work, including WMG鈥檚 High Value Manufacturing Catapult and . WMG鈥檚 Battery Forensic Group, led by Dr Mel Loveridge is keen to engage with industry and academia alike to grow advances in understanding new materials, battery performance and degradation modes.
