Abstract
The effectiveness of implementation of Green Supply Chain Management (GSCM) can be evaluated by assessing a set of categorical indicators, structured to capture the complexity observed in selected, representative practices usually present in GSCM. The objective of this article is to test and refine a model for the evaluation of the effectiveness of implementation of GSCM in industrial supply chains (SC). Barriers, drivers, green strategy formulation, green procurement, green distribution, reverse logistics, ecodesign, green market, waste disposal, among other greening practices, are present in the model. The research question is how to evaluate the effectiveness of implementation of GSCM in industrial SC? The research method is the qualitative modeling. Previous research proposed a model consisting of three constructs, supported by three sets of green practices, associated with categorical indicators. The constructs are green strategy, green innovation, and green operations. The effectiveness of implementation of each practice is assessed by a five points Likert scale [1 = very high; 0.75 = high; 0.5 = fair; 0.25 = weak; and 0 = null] answered by managers of the SC. Two real-world applications were made in two supply chains of the automotive industries, including suppliers, distributors and logistic operators. The focal companies are a tractors and engines manufacturer, and an electric auto parts manufacturer. The results were integrated by an importance vector obtained by Analytical Hierarchy Process (AHP) method and provided an overall index that can range between 0 % and 100 %. This index informs the global level of implementation of GSCM. The specific results of the cases were 76.25 % and 71.76 %. Improvement actions towards GSCM, conducted by management, should focus on the practices of the constructs with lowest contribution, green strategy and green innovation, respectively.
