November-December

 

Merry Christmas everyone! As we entered the holiday season, some of our recent news were:

 

 

 

  • Our paper entitled "Learning with Imbalanced Data in Smart Manufacturing" has been accepted for publication in IEEE Access.  The study addresses the challenge of imbalanced data in manufacturing applications by comparing extant techniques proposed in literature and proposing a comprehensive framework that considers data preparation, pre-processing, classifier design, and post-processing. 
  • Our paper entitled "How does the position of firms in the supply chain affect their performance? An empirical study" has been accepted for publication in Applied Network Science.The paper discusses the relationship between the topological position of firms in complex supply networks and their performance, finding the diminishing returns relationship between a supplier's centrality and its performance.
  • Our new book chapter entitled "Artificial Intelligence in the Supply Chain: A Classificaiton framework and Critical Analysis of the Current State" has been published in the Oxford Handbook of Supply Chain Management, edited by Thomas Y. Choi, Julie Juan Li, Dale S. Rogers, Tobias Schoenherr and Stephan M. Wagner. The chapter conceptualises the topic of Supply Chain AI thorugh a human-mimicking intelligent agent that exhibits spart supply chain behaviour, and reviews its capability blocks. 
  • MAG participated in the Digital Manufacturing Week showcasing both the AgentChat project and the PitchIn Autonomous Supply Chain demonstrator.
  • Alexandra participated in the Sheffield TechExpo panel on IoT to discuss how IoT can help with Manufacturing and Supply Chain resilience. Discussions centred around how 5G, and Cybersecurity challenges may impact the successful adoption of IoT.
  • Our weekly Pitch in webinars came to a close, having generated lots of good discussion around IoT in Manufacturing. We will be rerunning the series in the Spring to report on project mini-project results - please get in touch if you are interested in joining. More information on Pitch-In mini-projects are found here

 

September-October

  • Welcome to Michaelmas 2020! 
  • Congratulations to Edward Kosasih, who has passed his MPhil viva. Edward’s dissertation focused on the use of Reinforcement Learning (RL) approaches for safety stock optimisation, finding that RL offers flexibility to incorporate more realistic optimisation set ups and allows for innovative solution emergence, as compared to traditional approaches.
  • Congratulations to Dr. Tim Pearce, who has passed his PhD viva. Tim’s research contributed to the field of Bayesian neural networks by providing methods that enable uncertainty quantification in deep learning while remaining very practical and scalable – which is a primary concern in assessing the applicability of AI in real-world engineering problems. 
  • Welcome to our new PhD student Wangchujun Tang, who will work on distributed multi-agent systems for decentralised supply chains.
  • Our paper entitled “The relationship between nested patterns and the ripple effect in complex supply networks” has been published in the International Journal of Production Research. In this paper we analyse the effects of nestedess on supply chain disruption cascades. ‘Nestedness’, is defined as a pattern of organisation where products that are supplied by specialist suppliers are a subset of products that are supplied by generalist suppliers. In other words, generalists are also specialists. We find that nested organisations are significantly more robust to random disruptions but vulnerable to hub disruptions under cascade conditions. However, nested structures are not as resilient; as they do not benefit from a response strategy where buyers seek alternative suppliers; because alternative suppliers do not exist. 
  • We showcased our Autonomous Supply Chain demonstrator, developed in collaboration with Fetch.ai  during an online webinar which has attracted more than 85 participants, leading to discussions around how agent based system approaches could couple with digital currencies. Find more about the project here. 
  • We are going to participate in the Digital Manufacturing Week to discuss the Pitch In and AgentChat projects - come and speak to us!
  • Our first Data Study Group in Agrifood supply chain resilience took place virtually in September, with 30 researchers from across the UK. The study has been facilitated by the Isaac Newton Institute of Mathematical Sciences and the Knowledge Transfer Network. We have started creating methods to identify products and countries that are the most critical among the UK’s agricultural network dependencies and to understand how these dependencies evolve over time. For more information please contact: ab702@cam.ac.uk
  • We are starting weekly webinars on Pitch-In Manufacturing mini-projects, and have an exciting series of 16 mini-project presentations. Please get in touch if you’d like to know more.


June - July: 

  • We are presenting two papers at ICML this year: "Bayesian Autoencoders: Analysing and Fixing the Bernoulli likelihood for Out-of-Distribution Detection" by Xiang,  and "Structured Weight priors for convolutional neural networks" by Tim. 
  • Yaniv will present his paper on "Distributed Dynamic Measures of Criticality for Telecommunication Networks" in the upcoming SOHOMA
  • Liming, Stephen and Alexandra presented our recent work on the AgentChat project in the Connected Everything Conferencein July. 
  • MAG is organising a data study on the UK’s resilience to supply chain shocks in the Agrifood Sector. This study group will take place over two sessions. This first session (7 – 8 September) aims to assess the resilience of the UK food networks, while a second session later in the year will take the representations and learning from session one to look the UK food network response to specific shocks. The event is organized by us, Queen Mary, Knowledge Transfer Network, Isaac Newton Institute for Mathematical Sciences and the Alan Turing Institute. We are particularly interested to hear from researchers in data science, statistical modelling and network science.  Please contact ab702@cam.ac.uk if you are interested in taking part. 
  • Boyang Song from the University of Sheffield, introduced us to his work on  “ An Industrial Internet of Things (IIoT) & Deep Learning approach for Predictive Maintenance (PdM)". As part of the Pitch In project we are collaborating with Sheffield to understand how machine learning approaches can be used to improve data challenges in manufacturing quality control. 

April - May: 

 

  • As the Covid-19 pandemic hit the world, MAG, like most other research groups, has moved to remote working. While our research largely goes on without interruption, MAG is undertaking a number of activities to help combat the crisis:
  • First of these is  the setting up of an AgriFood Resilience forumwith UK’s Mathematical Sciences Research Community. The forum, organised by the Innovate UK and Knowledge Transfer Network will discuss ways in which UK’s Mathematical Sciences community can help combat disruptions to the UK’s food supply and logistics. The forum has published its first report and then gave its first webinar on the 28th April, attracting more than 130 participants. As part of the webinar series MAG presented how Network Science and Modelling can help understand disruption risks in large scale supply systems. Find more details   
  • MAG members have participated in IfM’s Covid-19 taskforce, which includes the development of simulation models to predict patient flows and capacity at Addenbrookes Hospital. Find more about IfM’s initiatives on Manufacturing and Covid-19 
  • MAG is starting a very timely new project with Aviva on supply chain risk. The project will investigate how rare, catastrophic events can be modelled and how insurance providers can help businesses combat interruption.
  • Stephen shared a best presentation award with two other researchers at the annual IfM PhD Conference. Many congratulations to Stephen!
  • Edward was selected to participate in the prestigious Max Planck Pre-doctoral School 2020 taking place in Cornell, Maryland. 
  • Our collaborative research with Cranfield University on Aerospace Ecosystem Networks has been published in PLOS ONE: Jose LA Jr, Brintrup A, Salonitis K (2020) Analysing the evolution of aerospace ecosystem development. PLOS ONE 15(4): e0231985.The paper investigates how network patterns emerge and change over time, comparing countries with developed and emerging Aerospace industrial sectors. 


 February-March 2020

  • MAG researchers Liming Xuand Stephen Mak won a feasibility study grant from the UK Connected Everything Network. Our new project, AgentChat, will explore the feasibility of enabling freight co-loading using agent-based technology.  Although the idea of freight co-loading has been around since sometime, its implementation has been challenging due to information asymmetry and difficulties involved in manual orchestration: co-located or close suppliers do not know whether they are sending items to similar locations around the same times unless someone tells them. Third-party mediation only works if sufficient agents sign up, and retailers or logistic providers incur transaction costs for orchestration. Our approach will explore how distributed, automated solutions can tackle this problem and what information infrastructures need to be in place for it to be adopted.
  • Many congratulations to Edward and Stephen who won first prize in the Aviva Data Science Hackathon organised by the Cambridge University Data Science Society!
  • Xiang and Yasmin will be presenting our paper in the  IEEE Metrology for Industry 4.0 and IoT conference taking place in  Rome in June 2020. The paper details the development of a Bayesian Autoencoder for detecting drift in industrial sensor data-based prediction. 
  • Welcome to Dr Jie Zhang, who joins us from Greenwich University to work on the Supply Chain Digital Twin project.
  • Edward discussed his research at the Indonesian Current Affair Discussion held in Lady Margaret Hall, Oxford, exploring the philosophical idea of a virtual twin and how it is related to Digital Twinsof today.
