The behavioural best-worst method

The best-worst method is a recent and promising highly-developed multi-criteria decision-making technique. However, the algorithm proposes a range of possible weights. To help decision-makers, we incorporate three different types of behaviour (i.e. balanced, risk-taking, and risk-averse) to select the best point for each weight. To this end, we develop three mathematical algorithms modelling the different behaviours. An example is presented to illustrate the behaviour of each algorithm. The different behaviours may lead to different results.
