Risk assessment in synchronous and asynchronous complex business networks
Applications are now CLOSED
This proposed research aligns to the new Advanced Research and Engineering centre (ARC) within Northern Ireland. This Centre will drive future innovations in technology and enhance our capabilities in important research areas such as robotic process automation (RPA), workflow automation, visualisation, data analytics and artificial intelligence (AI). The Centre brings together expertise from PwC, University of Ulster, and Queen’s University Belfast. This research project aligns to the workflow and AI streams within the Centre. A selection process will determine the strongest candidates across a range of projects, who may then be offered funding for their chosen project. This project is expected to explore operable business processes over a complex network covering multiple data sources. Depending on the type of data, the complexity of the porting software, and the dependencies between the data, these sources of data may have synchronous, asynchronous, or both characteristics. The business networks make decisions based on these inputs and are susceptible to error due to the data's multiple interconnections. As a result of the associated complexities and interdependence of the data points, several risky decision-making factors are frequently overlooked when a model of operations is so intricate. In a broader sense, failure to identify risk can result in inputs remaining undiagnosed for a longer period, leading to significant and more pervasive deficiencies over time. Thus, it is desired to develop methods to comprehend these entanglements of data from multiple sources in synchronous or asynchronous business networks and to provide solutions to flag the potential risks. In addition, reducing false positives without compromising the accuracy of risk mapping is an additional challenge that must be addressed as part of this project.
Business networks with multiple data points are challenging to map and profile for risks. This project is anticipated to investigate executable business processes over a complex network containing various synchronous and asynchronous data sources. The project will expand the understanding of the risk landscape and generate valid methods that can replace the existing clause approaches with more comprehensive and novel AI-assisted methods that can dynamically adjust the criteria without affecting the system's accuracy. The project will explore business processes and networks from multiple directions – link analysis, relationships between data and suspicious workflow, security risks, to name a few. Such provisioning will ensure that business decisions are taken based on true data by considering potential risks associated with the processes.
The project aims to develop methods of defining checks and clauses with the assistance of computational game theory to reduce the false positives in the risk flagging system and introduce potential reasoning capabilities within the mappings for synchronous and asynchronous business networks that support coordinated decision-making.

To do a PhD was one of the most challenging but rewarding decisions I have taken. While having a PhD was helpful in the job market, the real benefit was in stretching my mind and deepening my thinking. This is proving particularly useful as I head up a new local R&D team which has to stay ahead of the game by exploiting the latest research.

People teaching you
Course structureThere is no specific course content as such. You are expected to take research training modules that are supported by the School which focus on quantitative and qualitative research methods. You are also expected to carry out your research under the guidance of your supervisor.
Over the course of study you can attend postgraduate skills training organised by the Graduate School.
You will normally register, in the first instance, as an ‘undifferentiated PhD student’ which means that you have satisfied staff that you are capable of undertaking a research degree. The decision as to whether you should undertake a PhD is delayed until you have completed ‘differentiation’.
Differentiation takes place about 8-9 months after registration for full time students and about 16-18 months for part time students: You are normally asked to submit work to a panel of up two academics and this is followed up with a formal meeting with the ‘Differentiation Panel’. The Panel then make a judgement about your capacity to continue with your study. Sometimes students are advised to revise their research objectives or to consider submitting their work for an MPhil qualification rather than a doctoral qualification.
To complete with a doctoral qualification you will be required to submit a thesis of approx 80,000 words and you will be required to attend a viva voce [oral examination] with an external and internal examiner to defend your thesis.
A PhD programme runs for 3-4 years full-time or 6-8 years part-time. Students can apply for a writing up year should it be required.
The PhD is open to both full and part time candidates and is often a useful preparation for a career within academia or consultancy.
Full time students are often attracted to research degree programmes because they offer an opportunity to pursue in some depth an area of academic interest.
The part time research degree is an exciting option for professionals already working in the education field who are seeking to extend their knowledge on an issue of professional interest. Often part time candidates choose to research an area that is related to their professional responsibilities.
If you meet the Entry Requirements, the next step is to check whether we can supervise research in your chosen area. We only take students to whom we can offer expert research supervision from one of our academic staff. Therefore, your research question needs to engage with the research interests of one of our staff.
- Assessment processes for the Research Degree differ from taught degrees. Students will be expected to present write up their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually.
This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year.
The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.
- Supervisors will offer feedback on the research work at regular intervals throughout the period of registration on the degree.
Full time PhD students will have access to a shared office space and access to a desk with personal computer and internet access.
The minimum academic requirement for admission to a research degree programme is normally an Upper Second Class Honours degree from a UK or ROI HE provider, or an equivalent qualification acceptable to the University. Further information can be obtained by contacting the School.
For information on international qualification equivalents, please check the specific information for your country.

Computer Science costs
There are no specific additional course costs associated with this programme.
Additional course costs
Depending on the programme of study, there may also be other extra costs which are not covered by tuition fees, which students will need to consider when planning their studies . Students can borrow books and access online learning resources from any Queen's library. If students wish to purchase recommended texts, rather than borrow them from the University Library, prices per text can range from £30 to £100. Students should also budget between £30 to £100 per year for photocopying, memory sticks and printing charges. Students may wish to consider purchasing an electronic device; costs will vary depending on the specification of the model chosen. There are also additional charges for graduation ceremonies, and library fines. In undertaking a research project students may incur costs associated with transport and/or materials, and there will also be additional costs for printing and binding the thesis. There may also be individually tailored research project expenses and students should consult directly with the School for further information.
Some research programmes incur an additional annual charge on top of the tuition fees, often referred to as a bench fee. Bench fees are charged when a programme (or a specific project) incurs extra costs such as those involved with specialist laboratory or field work. If you are required to pay bench fees they will be detailed on your offer letter. If you have any questions about Bench Fees these should be raised with your School at the application stage. Please note that, if you are being funded you will need to ensure your sponsor is aware of and has agreed to fund these additional costs before accepting your place.
