Commercial Value Evaluation of Green Biotechnology Based on Ecological Resource Environmental Monitoring and Economic Benefits: A Multi-Criteria Framework With Monitoring Reliability

This paper proposes a neutrosophic–fuzzy MCDM framework that links (i) ecological-resource and environmental monitoring indicators, (ii) economic and techno-economic performance, and (iii) evidence reliability. First, heterogeneous monitoring and economic data are converted into single-valued neutrosophic numbers and then into a normalized crisp decision matrix. Second, two complementary MCDM rankings are fused into a Composite Value Index (CVI). Third, CVI is adjusted by a Monitoring Reliability score (MR) that aggregates monitoring completeness and stability via a policy preference parameter α, yielding the monitoring-adjusted index NFMA-CVI = MR × CVI. A China-oriented case study evaluates seven green biotechnology pilot options under 17 criteria. The value-only CVI favors algae CO2-to-biomass/bio-products (A5), whereas the monitoring-adjusted NFMA-CVI selects food-waste fermentation to biochemicals (A7) as the best option, followed by anaerobic digestion with biomethane upgrading (A3) and A5. Baseline comparisons reproduce the same top-tier split (A5 versus A7).
