I am Professor of Operational Research and Operations Management, and hold the DSV Chair of Manufacturing and Logistics. I am Director of the joint University-Industry PARC Institute of Manufacturing, Logistics and Inventory. I am also the Director of Cardiff University's RemakerSpace. I co-chair the Strategy and Advisory Board of the Logistics and Operations Management (LOM) Section of Cardiff Business School.

My research looks at supply chain forecasting and inventory optimisation, and has been instrumental in creating an integrated view of these two (formerly siloed) disciplines. My name is associated with inventory forecasting for intermittent demand items (which are items at the higherst risk of obsolescence). I am principally known for the Syntetos-Boylan Approximation, a standard forecasting method, and the Syntetos-Boylan-Croston approach to forecast classification. My 2021 book with John Boylan on Intermittent Demand Forecasting is available on the Wiley website. The contribution of the book is summarised in this short video.

Over recent years, I have undertaken research into inventory forecasting issues in circular (closed loop) supply chains and additive manufacturing (3DP) enabled supply chains. The union of these two areas underpins the RemakerSpace centre, a Welsh Government funded, not-for-profit, community and business engagement initiative, that supports product life cycle extension and ending planned obsolescence. The RemakerSpace resides in Cardiff University's Social Science Research Park (SPARK).

My research reflects collaboration with more than 40 universities and companies around the world, and it has been supported, primarily, by the Engineering and Physical Sciences Research Council (EPSRC, UK) and Innovate UK, with funds exceeding £5 Million (almost all of which I have secured as Principal Investigator). I have been published in leading academic outlets such as Decision Sciences, European Journal of Operational Research, Journal of Operations Management, and Production & Operations Management.

I have advised many organisations on inventory forecasting related matters and several methods/ algorithms I have co-developed are being utilised by major software corporations and have had an enormous economic impact (estimated in 2014 to be of at least £1 billion worth of reduced inventories) and environmental benefit. Over the last few years, I have been working closely with: Accolade Wines, British Telecommunications (BT), Brother International, DSV, the Excelitas group (Qioptiq), Ocado, and the Efficient Consumer Response (ECR) group (through which I am working with Europe's largest retailers). A summary of my recent impact can be found here.

I am Editor in Chief of the IMA Journal of Management Mathematics (IMAMAN, Oxford University Press) and Associate Editor of FORESIGHT, the practitioner oriented publication of the International Institute of Forecasters (IIF). I served as Director of the IIF in 2014 - 2022, and I currently serve at the Executive Committee of the International Society for Inventories Research (ISIR), chairing the Inventory Forecasting Section of the Society.

At Cardiff University, I have received awards for excellence in postgraduate teaching, the 2016 Cardiff University Outstanding Doctoral Supervisor Award (2016 Enriching Student Life Awards, ESLA) and the 2016 and 2019 Cardiff University Innovation and Impact Award in Business for my work with Panalpina World Transport Ltd. and Qioptiq Ltd., respectively.

Teaching - Cardiff University

My time is devoted 100% to research (and knowledge transfer).

Previously, in Cardiff Business School, I taught Logistics Modelling, Operations Analytics and Operations Management at the MSc programmes of the Logistics and Operations Management (LOM) Section. I have contributed considerably to curriculum development (e.g. Operations Analytics module) and have received awards for excellence in postgraduate teaching.

Teaching - Internationally

In addition to the UK, I have taught internationally in China, Colombia, Denmark, France, Greece, Italy and Latvia. All courses were in the areas of Operations Management, Operational Research (Management Science) and Applied Statistics.

Research interests

I work in the area of Operational Research and Operations Management, and I am interested in developing theoretically rigorous yet practically viable and effective inventory and/or forecasting algorithms and business models.

I have worked, and continue to do so, on intermittent demand inventory forecasting. This work is particularly relevant to spare parts (and after sales) supply chains. I am also working on inventory forecasting in the context of closed loop supply chains (circular economy) and additive manufacturing (3DP in particular) enabled supply chains. My work has always been underlined not only by financial but also environmental, and more recently social, concerns. I have always been pre-occupied with reducing inventory obsolescence, and more recently, with opportunities to stop planned obsolescence altogether.

My current research interests are around the following areas:

Statistical and judgmental supply chain forecasting
Inventory mathematical modelling and management
Analytical and conceptual unification of Inventory-Forecasting
Inventory Forecasting in: i) spare parts, ii) after sales, iii) retail, iv) close loop, v) 3DP-enabled supply chains
Inventory (and/or) Forecasting for environmental sustainability: obsolescence reduction or elimination
Inventory (and/or) Forecasting for social good
