Solving multi-objective transportation problem with interval goal using utility function approach

This paper presents the study of transportation problem (TP) with interval goal under multiple objective environment. Most of the multi‐objective transportation problems (MOTP) are solved by goal programming (GP) approach. Using GP, the solution of MOTP may not be satisfied all time by the decision maker (DM) when the proposed problem contains interval‐valued aspiration level. To overcome this difficulty, here we propose the approaches of revised multi‐choice goal programming (RMCGP) and utility function into the MOTP, and then compared the solution between them. Finally, a real‐life problem on TP is considered to show the feasibility and usefulness of our paper.
