Have I been doing Behavioural OR for the Last 20 Years? Stewart Robinson Professor of Management Science Associate Dean Research School of Business and Economics
Outline To develop a better understanding of behavioural OR. My research Examples of modelling behaviour Examples of understanding behaviour with models Some key elements of BOR
My Research Simulation practice Simulation conceptual modelling Simulation output analysis Facilitated modelling with simulation Comparison of DES and SD Agent-based simulation Verification and validation of simulation models The quality of operational research interventions Modelling human decision- making and interaction

A Lorry Loading Bay Problem: Decision tree derived from example cases using a simulation model Modelling Behaviour Part I: 1995
Investigation of the operations system Understanding the process and the decision- making required Elicit knowledge Decisions taken under scenarios (data sets held for each decision-maker) Trains Represent the decision-making strategy of each decision-maker Provide input to the VIS in place of the decision-makers Generate decision- making scenarios Predict performance of decision-making strategies Seek improvements VIS model AI model Data sets Stage 1 Stage 5 Stage 4 Stage 3 Stage 2 Modelling Behaviour Part II: Knowledge Based Improvement
