Some Transportation Problems Under Uncertain Environments

Transportation problem (TP) is a very important area in operations research and management science. TPs not only involve with cost minimization, but also involve with many other goals such as profit maximization, time minimization, minimization of total deterioration of goods, etc. Also the available data of a transportation system such as transportation costs, resources, demands, conveyance capacities are not always crisp or precise but are uncertain. In this dissertation some transportation problems have been formulated and solved in different uncertain environments, e.g., fuzzy, type-2 fuzzy, rough and linguistic.
