In this study the RL is investigated in a network of various industries with different kinds of material, which differentiates the problem in terms of the size and the related strategies for modeling and network design.
Due to the large size of the problem and its NP-hard complexity, a heuristic method based on genetic algorithm is introduced to solve the model more efficiently.
The material flow network of the problem is considered as a “Generalized Network” because of the loss/gain possibilities.
