From: Improving the production of applied health research findings: insights from a qualitative study of operational research

Operational research (OR) is the discipline of using models and analysis to aid decision-making in complex systems and has been used in healthcare since the 1950s [19]. The features of the problem being addressed inform the choice of approach adopted by OR practitioners, which can include qualitative methods such as problem structuring and conceptual modelling as well as quantitative data analysis, mathematical modelling and simulation techniques [46].
