Allocating shadow prices in a multiobjective chance constrained model for biodiesel blending

Biodiesel production sustainability relates to decision making on blending involving economic and environmental criteria. Several feedstocks candidate in European countries biodiesel industry, namely different vegetable origin oils. The present research aims at assessing the impact of technological constraints allocated to the decision objectives taking into account inherent uncertainty. For this purpose chance?constrained programming is used in order to maintain tolerance towards fuel quality.
