Base Criterion Method (BCM)

The base criterion method (BCM) is one of the latest MCDM methods introduced to obtain the weight of the criteria. This method was introduced in 2020 by Haseli et al. The BCM method uses the pairwise comparison approach to obtain the weight of the criteria. This method removes a large number of unnecessary comparisons by dividing pairwise comparisons into two categories: base comparisons and final comparisons. To obtain the weight of the criteria with the BCM method, only base comparisons are needed. In the base comparisons for n criteria, n − 1 pairwise comparisons need to be performed. The results in the BCM method will be fully consistent because instead of the controlling outputs of the pairwise comparisons to measure the inconsistency, the BCM method controls the inputs of pairwise comparisons. By controlling the input values of pairwise comparisons, there will be no more errors in the process of obtaining weights. The zero error accuracy means optimal and full consistent weights. Therefore, the BCM method can obtain the optimal weight of the criteria quite accurately. Also, it is required to perform fewer pairwise comparisons compared to the other existing MCDM methods. In this chapter, examples are provided to become more familiar with the problem-solving process for obtaining the weight of criteria using the BCM method.
