Unbalanced transportation problem with pentagonal intuitionsitic fuzzy number solved using ambiguity index

Triangular approximations of fuzzy number with value and ambiguity functions

Fully Fuzzy Transportation Problem

Transportation problem is a linear programming which considers minimum cost for shipping a product from some origins to other destinations such as from factories to warehouse, or from a warehouse to supermarkets. To solve this problem simplex algorithmis utilized. In real projects costs and the value of supply and demands are fuzzy numbers and it is expected that optimal solutions for determini...

Fuzzy Transportation Problem with Random Transportation Costs

We consider the following transportation problem with both random and fuzzy factors. There exist m supply points and n demand points. For each route between supply point and demand point, unit transportation cost is a random variable according to a normal distribution and existence possibility denoting the preference choosing this route is attached. The probability that the total transportation...

Optimization of Unbalanced Fuzzy Transportation Problems

In this paper, a method is proposed for solving an unbalanced fuzzy transportation problem without converting into a balanced one. The advantage of this method is that it gives an optimal solution. In the proposed method transportation costs, demand and supply are represented by triangular fuzzy numbers. To illustrate the proposed method, a numerical example is solved and the obtained result is...

Izpm for Unbalanced Fuzzy Transportation Problems

Modifications to Vogel’s Approximation Method for obtaining initial solutions to the unbalanced transportation problem are described by many workers. This paper presents a simple and efficient method that is better than the existing methods, easy to understand and also can give an optimal solution. The proposed method, Improved Zero Point Method (IZPM) (see [13]), is used for solving unbalanced...
