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 tacti...

Context: The Next Release Problem involves determining the set of requirements to implement in the next release of a software project. When the problem was first formulated in 2001, Integer Linear Programming, an exact method, was found to be impractical because of large execution times. Since then, the problem has mainly been addressed by employing metaheuristic techniques. Objective: In this ...
