On Solving of Rough Interval Multi-objective Transportation Problems

A new method namely, separation method [15], we apply this concept for rough interval based on upper upper interval (UUIT), upper lower inter- val (ULIT),lower upper interval (LUIT) and lower lower interval (LLIT), are proposed On Solving of Rough Interval Multi-objective Transportation Problems (RITP) where transportation cost, supply and demand are rough intervals. The separation method can be served as an important tool for the decision makers when they are handling various types of logistic problems having rough interval parameters of transportation problems. The solutions of four problems (UUIT, ULIT. LUIT, LLIT) constrict to the rough solution set of our (RITP) and also the optimal transportation cost. The solution procedure is illustrated with a numerical example.
