Use of some multicriteria decision-making methods such as grey relational analysis (GRA), the complex proportional assessment (COPRAS), and weighted aggregated sum product assessment (WASPAS) in selection of some Anatolian pine (Pinus nigra Arnold.) origi

Aiming to determine the quantitative sapling characteristics that are important for nursing methods, present study was carried out on 2-year-old naked root Anatolian Black Pine (Pinus nigra Arnold. subsp. pallasiana (Lamb.) Holmboe) saplings obtained from four different seed origins Denizli Forest Sapling Nursery Directorate. In this study, selection of these examined using multicriteria decision-making methods (MCDM) by determination differences between and use suitable in practice. Within context weight coefficients (significance degrees) such as height, neck diameter, last-year shoot length, length were measured Criteria Importance Through Intercritera Correlation (CRITIC) method. Secondly, development performances black pine Grey Relation Analysis (GRA), The Complex Proportional Assessment (COPRAS) Weighted Aggregated Sum Product (WASPAS) methods. Besides that, since CRITIC-based GRA, COPRAS, WASPAS showed complete consistency terms performance ranking, proportional values very close each other, have positive high levels relationships with it considered can be alternative other any measurement ranking or measurement. Accordingly, all (GRA, WASPA) successfully implemented origin selection. Given results obtained, determined three İnceler ranked first Çatak last.
