A MINLP Model to Optimal Design of ? Sustainable Dairy Supply Chain Taking into Account Preferences of the Network Actors

The increase of pollutants generated in the production of dairy products, the increase of the production costs and emerging social problems requires the development of approaches for resilience improvement of the considered product productions. An effective way to achieve this is by optimising all a...
