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. My business web profile is here.

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 UniversityMy past leadership roles include the Director of Postgraduate Teaching at the Department of Management Science, Lancaster University Management School overseeing MSc programmes in Business Analytics, Management Science and Marketing Analytics, Logistics and Supply Chain Management, e-Business and Innovation, and Project Management.

I have two PhD scholarships deadline: 24 January 2019:

  • Designing interventions to prevent plastics from getting into the sea: A behavioural-science approach to understand and improve the decision rules of stakeholders in Citarum river – more information
  • Developing a hybrid simulation approach to planning mental health services – more information

Currently, I am involved in the organisation of the following conferences:


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 operations and supply chain management (e.g. hospital, manufacturing, transportation, warehouse) and social dynamics (e.g. diffusion of perception). 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 2016 are:

  • Symbiotic Simulation: Hybrid Systems Model Meets Big Data Analytics (Accepted for the Proceedings of the 2018 Winter Simulation Conference)
  • Multi-fidelity Simulation Optimisation For Airline Disruption Management (Accepted for the Proceedings of the 2018 Winter Simulation Conference)
  • Agent-Based Simheuristics: Extending simulation-optimization algorithms via distributed and parallel computing (Accepted for the Proceedings of the 2018 Winter Simulation Conference)
  • Strengthening the Reporting of Empirical Simulation Studies: Introducing the STRESS guidelines – (JOS 2018 )
  • Applications of Agent-Based Simulation in the Agri-Food Supply Chains – (EJOR 2018, 269 (3):794-805)
  • A BPMN Extension to Support Discrete-Event Simulation for Healthcare Applications: An Explicit Representation of Queues, Attributes and Data-Driven Decision Points – (JORS 2018, 69(5):788-802)
  • Airline Disruption Recovery using Symbiotic Simulation and Multi-Fidelity Modelling – (Proceedings of the 2018 Operational Research Society’s Simulation Workshop (SW18), pp. 146-155).
  • Towards fully-facilitated discrete event simulation modelling: Addressing the model coding stage – (EJOR 2017, 263 (2): 583-595)
  • Test-driven simulation modelling: A case study using agent-based maritime search-operation simulation (EJOR 2016, 254(2):517-531)
  • Agent-based computational modelling of social risk responses (EJOR 2016, 251(3):1029-1042)
  • Approaching parallel computing to simulating population dynamics in demography (Parallel Computing 2016, 59:151-170)

My PhD supervision interests

I am willing to supervise doctoral students in the following areas:

  1. Research related to the interface between simulation modelling, artificial intelligence and big data analytics techniques.
  2. Research related to improving the practice of simulation modelling methods (agent-based simulation, discrete-event simulation, hybrid simulation, symbiotic simulation)
  3. Behavioural simulation (to understand how modellers build a simulation model, or how users use a simulation model for decision making)
  4. Social science simulation (evaluating and generating theories in social science including management theories)
  5. 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 November 2018, I have supervised five PhD students (four completed, one active) and examined PhD candidates from the following universities: Brunel (1), Dublin Institute of Technology (1), Lancaster (1), Limerick (2), Loughborough (1) and Warwick (1) as well as MRes/MPhil candidate from the following university: Dublin City University (1).


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 and System Dynamics).  My current and past institutions do not offer Agent-Based Simulation module so I only teach Agent-Based Simulation in invited tutorials / lectures / short courses.

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.

Current and past leadership roles

  • Director of Taught Postgraduate Programmes (Department of Management Science)
  • Director of MSc in Operational Research and Management Science
  • Department representative for IT Policy committee
  • Department representative for Compute Intensive Research Committee
