Nutritional Diagnosis Using AHP with the Garuti Index Compared with DRIS Methodology: A Case Study

Abstract

The objective of this study is to create a new Analytical Hierarchy Process (AHP) model incorporating the Garuti Index (Garuti 2012) to measure nutrients levels more effectively than the current Diagnosis and Recommendation Integrated System (DRIS) model. To create the model it was necessary to develop the hierarchy of the AHP including macronutrients, micronutrients, and the nutrients in general. The next steps was to measure the weight of all the components and create scales of diagnosis to calculate the Garuti Index and compare the results with the DRIS model. The data set were taken from a DRIS study performed by García S.(2000) on potato leaves from the States of Coahuila and Nuevo Leon in Mexico.
