Best-Worst Method (BWM) is a multi-criteria decision-making (MCDM) method developed by Dr. Jafar Rezaei (Delft University of Technology) in 2015. BWM can be used in various decision-making areas such as business and economics, health, IT, engineering and agriculture. In principle, wherever the aim is to rank and select an alternative among a set of alternatives, this method can be used. It can be used by one decision-maker or a group of decision-makers. The salient features of BWM, compared to most existing MCDM methods, are: (i) it requires less comparison data; (ii) it leads to more consistent comparisons, which means that it produces more reliable results.

The original BWM, which includes a non-linear model, and also a simplified BWM, which includes a linear model have been published as two papers in Omega, The International Journal of Management Science (a top journal in Operations Research/Management Science).
