Sensitivity analysis of supply and demand in a fully interval transportation problem

چکیده
In this paper, sensitivity analysis of supply and demand parameters of an interval transportation problem is presented. A new solution method namely, upper-lower method is proposed to determine the ranges of supply and demand parameters in an interval transportation problem such that its optimal basis is invariant. To illustrate the proposed method a numerical example is solved. Then, the upper-lower method is extended to fuzzy transportation problems. The study of sensitivity by the proposed method can be served as an important tool for the decision makers for taking appropriate decision when they are handling various types of logistic problems having imprecise parameters.

This paper is focused on the tactical design of steel supply chain (SSC). A general mathematical model is proposed to integrate production and transportation planning in multi-commodity SSC. The main purpose is to prepare a countrywide production and distribution plan in an SSC with three layers consisting of iron ore mines as suppliers, steel companies as producers, and subsidiary steel compan...
متن کاملFully 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...
متن کاملA Grey Transportation Problem in Fuzzy Environment
In classical transport models, it is always assumed that parameters such as the distance from each supply node to each demand node or the cost of transferring goods from one node to another, as well as quantities such as supply and demand are definite and definite amounts. But in real matters, considering these assumptions is not logical. On the other hand, there may be a real problem in mathem...

This study considers a reliable location – inventory problem for a supply chain system comprising one supplier, multiple distribution centers (DCs), and multiple retailers in which we determine DCs location, inventory replenishment decisions and assignment retailers to DCs, simultaneously. Each DC is managed through a continuous review (S, Q) inventory policy. For tackling real world conditions...
