A Neutrosophic-Based Approach in Data Envelopment Analysis with Undesirable Outputs

Algorithm 1

Solution of the SVNBCC-UO model.

	Step 1. Construct the problem based on Model (10).
	Step 2. According to Definitions 3 and 4, transform the SVNBCC-UO model of Step 1 into
	Step 3. By Definition 2, transform Step 2 into
	Step 4. Convert Step 3 into the following linear model:
	Step 5. Using Step 4, get the optimal efficiency of each DMU.
