A new approach in supply chain modeling

This paper introduces a new approach toward modeling supply chain. Instead of minimizing cost or maximizing benefit, we try to set the ratio of revenue to cost to a certain value and minimize cost in this condition, simultaneously. As this ratio is one of the decision criteria in economical engineering context, it may be attractive for industries to decide whether participate in this chain or not. An algorithm is proposed and tested to see whether this approach and this procedure work or not.
