Flows optimisation of industrial symbiosis based on bi-objective mathematical modelling

It seems clear that industrial systems can no longer continue to operate by taking unrestricted amounts of natural resources, especially when these are non-renewable. In order limit this over-consumption, the symbiosis principle is an interesting solution. The objective here determine, using a mathematical bi-objective model, optimal flow allocations within symbiosis. Our model applies at tactical and operational levels, i.e., already defined. aim study best possible distribution in maximise both overall economic symbiotic profits (defined as difference between internal external flows). With mind, we will conduct numerical application based on real example with generic values before presenting optimisation algorithm e-constraint method. Finally, simulations be performed evolution results.
