In this study a multi-stage multi-objective transportation model is developed with fuzzy relations. Minimization of both cost and time of transportation are considered as two different objectives of first stage which are associated with a number of different criteria like detortion time, fixed charge and mode of transportation. In second stage, another objective quantity of transported amount is considered on the basis of previous two objectives. | A study on multi stage multiobjective transportation problem under uncertainty environment using mamdani fuzzy inference system
