3. EFFICIENCY MEASURE OF MOROCCAN SUPPLIERS ACCORDING TO THE DEA MODEL

Résumé

This paper explores to conduct of a comprehensive analysis of the efficiency of Moroccan suppliers using the DEA model (Data Envelopment Analysis), implemented through the R software. In an increasingly competitive and digitalized economic environment, supplier performance is a key success factor for Moroccan companies, as it directly affects the quality of delivered products or services, cost control, delivery punctuality, and innovation capacity. The evaluation of efficiency is based on a rigorous quantitative approach, comparing the resources utilized (inputs) with the results achieved (outputs), without assuming any predefined production function. The study sample consists of 19 Moroccan suppliers, selected for their representativeness and the availability of relevant data. The considered inputs include invested capital, number of employees, and years of experience, while the outputs measure turnover, number of clients, digitalization rate, delivery reliability, level of innovation, and product or service quality. The analysis showed that 11 suppliers achieved an efficiency score of 1, indicating that they use their resources optimally to produce satisfactory outcomes. The remaining 8 suppliers, with scores below 1, show room for improvement. The model precisely identifies these areas by suggesting efficient reference targets and potential adjustments to enhance performance. This approach not only ranks suppliers according to their efficiency but also provides a strategic benchmarking tool to support companies in selecting, evaluating, and developing their supplier partnerships. The practical implications are numerous: improving the supplier selection process, offering targeted support to underperforming suppliers, strengthening relationships with efficient ones, and building a more resilient and agile supply chain. In conclusion, applying the DEA model to real-world data enables an objective, transparent, and comparative evaluation of Moroccan supplier performance, thus serving as a strategic lever for companies aiming to optimize their procurement management and overall competitiveness.
