Sustainable Operations & Supply Chain Management

Professor Nagati, Gong, Neubert and Rekik are active in this research field

Some of the research conducted by Professor Nagati illustrates the potential benefits for firms that report more on environmental activities, with regard to two important categories of stakeholders: shareholders and customers. based on the 120 largest publicly traded companies in France from 2007 to 2011, results suggest that shareholders interpret and perceive firms’ environmental information disclosure differently than consumers. However, reporting on environmental duties is perceived favorably by both customers and shareholders for firms with better environmental performance. In the same way, an increase in the level of environmental reporting is valuable in terms of customer-related performance.

By collecting data from 124 retailers, Professor ‘Gong research integrates the DEA model with empirical methods. The study permits to answer the questions: Is it always beneficial to increase firms’ sustainable operations for operational efficiency? Under which conditions should a retailer increase its socially-responsible and environmentally-friendly operations to improve efficiency?  This research addresses inconsistent viewpoints in relation to sustainable activities and performance at an operational level, and fills in research gaps in measuring the efficiency of, and identifying the operational mechanisms active in, sustainable retail operations.

Professor Rekik’s research contributes in designing innovative inventory and routing policies taking into account the environmental and particularly the CO2 emission as a constraint. The inventory routing problem (IRP) has attracted a particular interest, because it integrates two well-studied problems in supply chain management : inventory control and vehicle routing. These two issues have been traditionally dealt with independently, but their integration can have an impressive impact on overall system performance. Adding the green constraint to the inventory routing problem results in innovative and very interesting joint storage and distribution managerial insights.

In large industrial companies, procurement represents a huge opportunity for purchasing department to develop innovation which is increasingly the outcome of a collective effort rather than a product of a single firm. Integrating sustainability in the purchasing process requires a shift from the technical specifications to a more collaborative discussion on, and definition of, the proposed technical and non-technical specifications between the suppliers and procurer. Professor Gilles’s research contributes in designing global end to end solution, integrating product and services on the whole lifecycle of the offer, creating a sustainable value for a large set of stakeholders.
