Welcome to my blog. I will slowly add more topics on business analytics using simulation. I hope you find my blog useful. If you are looking for my business web page, please follow this link.
About me
My name is Dr. Bhakti Stephan Onggo SFHEA. I am an Associate Professor of Business Analytics at Southampton Business School, the University of Southampton. I am a member of the Centre for Operational Research, Management Sciences and Information Systems (CORMSIS), a Senior Fellow of the Higher Education Academy, an associate editor of the Journal of Simulation, and the chair of The OR Society‘s Special Interest Group in Simulation. I am also an Adjunct Teaching Fellow at Trinity Business School, Trinity College Dublin, The University of Dublin.
Previously, I was an Associate Professor of Data Analytics at Trinity Business School, Trinity College Dublin, The University of Dublin, and Assistant Professor in Operational Research at Lancaster University Management School, Lancaster University. My current and past leadership roles include Programme Leader for the MSc in Business Analytics & Management Sciences (Southampton), Director of Postgraduate Teaching (Lancaster) and Programme Director of MSc Business Analytics (Lancaster).
Currently, I am involved in the organisation of the following conferences:
- Track coordinator (Agent-based simulation) at the annual Winter Simulation Conference 2020 (Orlando FL, USA)
- Track coordinator (Agent-based simulation) at the annual Winter Simulation Conference 2019 (National Harbor, Maryland, USA)
Research
My research interests lie in the areas of business analytics using simulation. I am particularly interested in simulation modelling methodology (symbiotic simulation, hybrid modelling, agent-based simulation, discrete-event simulation) with applications in supply chain management, operations management and health and social care. Currently, I am the associate editor of the Journal of Simulation and the chair of The OR Society‘s Special Interest Group in Simulation.
My selected publications since 2017 are:

My PhD supervision interests
I am willing to supervise doctoral students in the following areas:
- Research related to the interface between simulation modelling, artificial intelligence and big data analytics techniques.
- Research related to improving the practice of simulation modelling methods (agent-based simulation, discrete-event simulation, hybrid simulation, symbiotic simulation)
- Behavioural simulation (to understand how modellers build a simulation model or how users use a simulation model for decision making; how to model human behaviour using simulation)
- Topic areas related to the applications of simulation in operations and supply chain management, health and social care, and application areas that benefit the most vulnerable in the society
As per July 2019, I have supervised five PhD students (four completed, one active) and examined PhD candidates from the following universities: Brunel (1), Cranfield (1), Lancaster (1), Limerick (2), Loughborough (1), Technological University Dublin (2) and Warwick (1).
Teaching
I teach mainly business / data analytics modules such as Data Analytics, The Foundation of Business Analytics and Consulting, Digital Analytics, Spreadsheet Modelling and Computer Programming (Python, C++ and VBA) for business and management students, and Simulation Modelling (Discrete-Event Simulation, System Dynamics and Agent-Based Simulation).
Consultancy work and project supervision
Occasionally, I carry out consultation projects. My past client includes the European Commissions, Greater Manchester Police, National Nuclear Lab, Graham Engineering Ltd (SME) and Enterprise Ltd (recently bought by Amey). Every year, I supervise Masters students who work on projects from May to August in an organisation as part of their degree. Recent organisations include Jaguar Land Rover, FORD Motor Company, BAE Systems, National Nuclear Lab, and Liverpool School of Tropical Medicine. If your organisation is interested to have access to some of our talented students please contact me.
