Addressing uncertainty in Lorie-Savage and Weingartner capital rationing models has been considered in the literature with different approaches. Stochastic and robust approach to Weingartner capital rationing problem are examples of non-fuzzy approaches. In this chapter, we provide examples of fuzzy approach to Lorie-Savage problem, and illustrate the models with numerical examples. The solution of the generic models requires evolutionary algorithms; however for the models with triangular or trapezoidal fuzzy numbers, branch-and-bound method has been suggested to be sufficient.
