Utilisation d'une méthode multicritère d'aide à la décision pour le choix des clones d'hévéa à planter en Afrique

Abstract

A multicriteria decision approach for selecting hevea clones in Africa. The main objective of this study is to settle a rigorous field of decision analysis for natural rubber clones selection. Nowadays there does not exist any process based upon a rigorous method to select the right clone for the right place to get the highest return on investment. The only known selection method is to use the experience of different protagonists acting in the plantation. So, we need a tool that takes into account different very important criteria in order to achieve the main objective. This goal is achieved by using multicriteria analysis methods to clone selection. The ranking procedure uses Electre III. For each criterion, indifference and preference thresholds are determined after establishing the relative importance of each criterion that includes rubber tapping, cumulative production during 15 years, cumulative production between 15 and 25 years, wind resistance, disease resistance, physiological resistance, grafting, quality of the hevea.
