Sensitivity Analysis of Costs in Interval Transportation Problems
نویسنده
چکیده
Sensitivity analysis of cost coefficients of an interval transportation problem is discussed. A new solution method namely, upper-lower method is proposed to determine the ranges of costs in the interval transportation problem such that its optimal basis is invariant. The proposed method is illustrated with the help of a numerical example. Further, the upper-lower method is extended to fuzzy transportation problems. Mathematics Subject Classification: 90B06, 90C08, 90C31.

Modeling and Analyzing Incremental Quantity Discounts in Transportation Costs for a Joint Economic Lot Sizing Problem
Joint economic lot sizing (JELS) addresses integrated inventory models in a supply chain. Most of the studies in this field either do not consider the role of the transportation cost in their analysis or consider transportation cost as a fixed part of the ordering costs. In this article, a model is developed to analyze an incremental quantity discount in transportation cost. Appropriate equatio...
متن کاملSensitivity analysis of supply and demand in a fully interval transportation problem
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...
متن کاملA Clustering Based Location-allocation Problem Considering Transportation Costs and Statistical Properties (RESEARCH NOTE)
Cluster analysis is a useful technique in multivariate statistical analysis. Different types of hierarchical cluster analysis and K-means have been used for data analysis in previous studies. However, the K-means algorithm can be improved using some metaheuristics algorithms. In this study, we propose simulated annealing based algorithm for K-means in the clustering analysis which we refer it a...
متن کاملA New Approach for Finding an Optimal Solution for Grey Transportation Problem
In ordinary transportation problems, it is always supposed that the mileage from every source to every destination is a definite number. But in special conditions, such as transporting emergency materials when natural calamity occurs or transporting military supplies during wartime, carrying network may be destroyed, mileage from some sources to some destinations are no longer definite. It is u...
متن کاملPlanning for Medical Emergency Transportation Vehicles during Natural Disasters
One of the main critical steps that should be taken during natural disasters is the assignment and distribution of resources among affected people. In such situations, this can save many lives. Determining the demands for critical items (i.e., the number of injured people) is very important. Accordingly, a number of casualties and injured people have to be known during a disaster. Obtaining an ...
