Transportation Problem • We have seen a sample of transportation (to p4) problem on slide 29 in lecture 2 • Here, we study its alternative solution method • Consider the following transportation tableau (to p6) 3 Review of Transportation Problem Warehouse supply of televisions sets: Retail store demand for television sets: 1- Cincinnati 300 All the solutions, however, are by the author, who takes full responsibility for their accuracy (or lack thereof).

Imagine yourself owning a small network of chocolate retail stores. Feasible Solution: A feasible solution to a transportation problem is a set of non-negative values x ij (i=1,2,..,m, j=1,2,…n) that satisfies the constraints. Formulate the given problem and set up in a matrix form. The remaining decision variables in that column (or row) are non-basic and are set equal to zero. • QUESTION:A company has three productionfacilities P1, P2 and P3 with productioncapacity of 7, 10 and 18 units per weekof a product, respectively. Break the ties arbitrarily (if there are any). 21. If all of the rows and columns that were not crossed out have zero supply and demand (remaining), determine the basic. Transportation problem is considered a vitally important aspect that has been studied in a wide range of operations including research domains. maximum number of products that can be sent from it) while each … Existence of Basic Feasible Solution: The number of basic variables of the general transportation problem at any stage of feasible solution must be (m + n – 1). warehouses). The data of the model includeeval(ez_write_tag([[580,400],'gatexplore_com-medrectangle-3','ezslot_2',107,'0','0'])); 1. warehouses). This is a special kind of the network optimization problems in which goods are transported from a set of sources to a set of destinations subject to the supply and demand of the source and destination, respectively, such that the total cost of transportation is minimized.

Transportation Problems:DEGENERACY, Destination Operations Research Formal sciences Mathematics Formal Sciences Statistics Solve the transportation problem when the unit transportation costs, demand and supplies are as given below. Enter the number of rows and columns and the values for supply and demand to know the total minimum cost. 4. The level of supply at each source and the amount of demand at each destination. < Operations Research. Suppose a company has m factories where it manufactures its product and n outlets from where the product is sold. If a column (or row) is satisfied, cross it out. If a row and column are satisfied simultaneously, cross only one out (it does not matter which). However, as soon as you expand and open a second warehouse, you will have to make an important decision: which warehouse will deliver which goods to each of your stores? The objective is to determine how much should be shipped from each source to each destination so as to minimise the total transportation cost.eval(ez_write_tag([[580,400],'gatexplore_com-medrectangle-4','ezslot_3',110,'0','0'])); eval(ez_write_tag([[300,250],'gatexplore_com-box-4','ezslot_4',111,'0','0'])); Details about balanced and unbalanced transportation problem you find in attached pdf notes at end of this article. the cell in the top left corner of the transportation tableau).
