November 2017: The SoFE Project –Social & Sustainable Fashion Entrepreneurs- has produced several results and deliverables, including Pilot Workshops and Cases from its community of social entrepreneurship initiatives. The project is now in its final phase with the Final Conference being planned for in Athens 19-20 November.

Androutsopoulos K.N., Kamaras N.K , (2017). Modelling And Solving A Real-Life Fuel Distribution Problem. 6th International Symposium and 28th National Conference on Operational Research, June 08-10, Thessaloniki, Greece.
Fuel delivery problems involve routing and scheduling heterogeneous vehicle fleets for replenishing a set of customers (petrol stations). In recent research, we address a fuel distribution problem taking into account safety considerations in the sequence of unloading orders. Developing and using a GRASP heuristic algorithm, the emerging solutions show important reductions both in travelled distance and in the number of vehicles used, compared to the existing route planning system of the company.
